However, machine learning can help detect these activities by identifying abnormal patterns​.
  1. Other Financial Fraudulent Types: This includes commodities and securities fraud, mortgage fraud, corporate fraud, and money laundering. Each of these involves different deceptive practices, and machine learning can help detect patterns and anomalies that suggest fraudulent activity in each of these areas​​.

There are a variety of machine learning techniques being used for fraud detection, with support vector machines and artificial neural networks being trendy. However, there are still challenges and limitations in the field, which present opportunities for future research and development​.

Algorithmic Trading

Algorithmic trading, the practice of executing trades using pre-programmed instructions, is a significant part of today's financial markets. Machine learning, and specifically deep reinforcement learning (DRL), has become increasingly relevant in this domain.

Deep Reinforcement Learning (DRL) and Algorithmic Trading: DRL uses a type of ML that learns from interacting with its environment, receiving positive or negative feedback in the form of rewards or penalties.

DRL agents have shown considerable potential in many complex games like Chess and Go, and this success has led researchers to apply these techniques to the stock market, a complex and imperfect information environment. The goal in the stock market is to maximize return or profit and minimize risk.

DRL in algorithmic trading is focused on developing automated low-frequency quantitative stock trading systems. These systems are designed to make trades with minimal human intervention based on historical market data and statistical indicators to decipher market patterns and take appropriate actions. The timeframe for these trades can range from one minute to several days, similar to how a human trader might operate.

Challenges and Limitations: Although many studies have shown statistically significant improvements in performance compared to established baseline strategies, achieving a decent level of profitability remains a challenge. Much of the research conducted has been in unrealistic settings with no real-time trading applications. There is also a lack of experimental testing in real-time on online trading platforms and a lack of meaningful comparisons between DRL agents, traditional strategies, and human traders.

Potential and Future Research: Despite these challenges, DRL in stock trading has shown tremendous potential. DRL systems have been found to compete with professional traders with respect to risk-adjusted return rates on short (15-minute) or long (daily) timeframes in specific markets. It's suggested that DRL systems could potentially surpass human performance in the future. However, this research is still in its early stages, and further studies are required to truly understand the potential of DRL in this environment​.


Many businesses employ automation to lower the expenses of manual activities. A bank, for example, may have a staff in charge of creating new account applications via an application programming interface.

The API team's work might be completely automated by leveraging machine learning to power fraud detection features within the API. This would free them up to focus on other activities at the bank, such as advising and educating customers on financial matters. In this case, the API team would still need to confirm that each customer qualifies for an account, but a different group of employees—or even completely automated—might handle that task entirely.

Using machine learning, this task can be largely or totally automated, freeing up workers to focus on more sophisticated elements of customers' accounts, such as assisting them in making long-term financial decisions or addressing their individual needs.

Churn prediction

Churn prediction is one area where machine learning might be useful in finance. This relates to determining which clients are likely to depart your company and when they will do so. Churn tracking enables businesses to find areas for development, such as offering better training to their advisers or improving the client experience.

Churn prediction assists in better understanding customers and even preventing churn before it occurs by providing them with relevant information and recommendations. Advisors can even identify which customers are most likely to leave with the correct tools and decide whether or not to invest time and resources in retaining those clients.

Risk assessment

Risk analysis is an essential component of any investment strategy. It entails assessing, collecting, and comprehending risks in order to better manage them. In finance, this entails recognizing potential risks in a transaction by combining quantitative and qualitative analysis - for example, estimating the predicted loss based on historical data or appraising risk based on characteristics such as industry concentration or macroeconomic conditions.

Machine learning algorithms, in addition to providing insight into transaction risks, can be used for risk management by quantifying those risks and allowing organizations to build policies around them. This assists organizations in developing effective trading strategies, limiting prospective losses based on previous patterns, and proactively protecting themselves from future threats.

Consequently, machine learning has become the most significant subset of the worldwide AI market in retail, with a predicted increase from $5.84 billion in 2021 to $18.33 billion in 2028​.

Inventory Management

Inventory management is a challenging task due to the volatility of retail markets, the fickleness of customers, and the risks associated with supply chains. These challenges, combined with the need to track shopper preferences, previous sales figures, historical trends, and online sentiments, make inventory management a complex endeavor.

Common problems with manual inventory management include reliance on internal sources, long system build times, the use of incorrect data, inaccuracy, and bias​.

Machine learning can bring numerous benefits to inventory management in retail:

  1. More Comprehensive Array of Data: Machine learning can capture a wider array of data, not just historical sales figures and patterns. It can consider factors like weather conditions, region, location, annual earnings, demographic data, social media mentions, and vendor purchasing habits based on significant events. This wide variety of data can provide more nuanced insights and allow for adjustments to unexpected market disruptions​​.
  2. Better Understanding of Data: With machine learning, retail businesses can better understand and organize the vast amounts of data they collect from various sources, such as site data and social media. Machine learning can help make connections, reveal patterns in customer behavior, and predict future market behavior or individual buyer actions. This can lead to more confident forecasting and better-managed inventory​​.
  3. Faster Results: Machine learning can automate much of the data preparation stage, speeding up the process of getting models into production and incorporating new external data sources. This means businesses can get the answers they need to manage their inventory in a timely manner, rather than waiting for a month when the industry may have already moved on​​.
  4. Reduced Bias: Machine learning can reduce the bias that can occur with manual forecasting systems that focus on average values and point predictions without taking uncertainty into account. By constantly feeding new information from different sources into the models, over-reliance on any one system can be reduced, and any systemic biases can be corrected​.
  5. Lower Inventory and Ordering Costs: By incorporating dynamic data streams into machine learning models, businesses can respond faster to market and customer preference fluctuations, ensuring they're only ordering what they need when they need it. This can lead to reduced inventory costs​​.

Machine learning in retail can track moods and trends and respond to them quickly, translating these insights into efficient inventory management that cuts costs while maximizing sales opportunities.

The potential of machine learning to make retail businesses more efficient and competitive is enormous. However, it's essential to use the right technology and have access to the necessary data sources without delay. The key is to create machine learning models that can adapt to new, up-to-date data sources to never miss a beat​.

Personalized Marketing

Machine learning can be applied across the entire sales cycle, from storage logistics to post-sale customer care. The technology allows businesses to convert complex data into actionable insights with little to no human intervention. It enables accurate forecasting of upcoming needs, improvement of inventory control, identification of consumer needs through appropriate segmentation, making product offerings more unique, and deciding on the optimum prices to increase sales.

This can lead to improved operational efficiency, reduced inventory costs, and the ability to modify retail operations to account for current and potential future market trends​.

Predictive analytics can forecast customer behavior, including recent purchases, Google search history, social network remarks, and solvency, and make the best choices regarding what kind of goods will suit the user and at which point he will need them​.

Machine Learning in Manufacturing

How Machine Learning is Transforming Manufacturing

Machine learning is transforming manufacturing, a sectoral shift that is part of the Fourth Industrial Revolution, or Industry 4.0. Machine learning is crucial to this digital transformation, training computers to think like humans and derive insights from vast quantities of real-world data.

This technology is used in various forms in manufacturing, including supervised and unsupervised machine learning. These forms have different applications, from identifying patterns in data and predicting future occurrences to inferring patterns from datasets without any predefined outcomes​.

Businesses across all sectors seek to leverage this technology while it is still in its early stages, and manufacturing is no exception​.

Predictive Maintenance

Machine learning is increasingly being utilized in the manufacturing industry, with one of its most impactful applications being predictive maintenance. This application of ML is designed to preempt the failure of vital machinery or components by identifying patterns that can predict when future maintenance will be needed.

Predictive maintenance has the potential to save manufacturers significant time and money by enabling them to tackle specific issues exactly when required and in a highly focused manner.

The key benefits to manufacturers include significantly reducing planned and unplanned downtime and the associated costs, providing technicians with focused inspection, repair, and tool requirements, prolonging the remaining useful life of machinery by preventing any secondary damage during repairs, and reducing the size of the technical team needed to make repairs​.

Predictive maintenance works by analyzing data from previous maintenance cycles. Heavy equipment such as engines, wind turbines, and manufacturing machines produce various streams of data, including heat, vibration, and time-series data.

Machine learning algorithms can detect "failure patterns" in this data, allowing businesses to maintain equipment health more effectively. The cost savings created by reducing downtime and failures can be substantial.

For instance, consider the costs associated with shutting down a manufacturing line at a large plant or an oil rig in the middle of the ocean.

Machine learning is well-suited to the complex pattern recognition required for predictive maintenance, even though finding suitable applications of sensors and algorithms is challenging​.

Predictive maintenance applications leverage a variety of data types, such as:

  • sensor data from the equipment itself,
  • Programmable Logic Controller (PLC) data,
  • computer vision,
  • time series data of known breakdowns,
  • issues or malfunctions,
  • and relevant external data sources.

Different equipment will require a diverse mix of sensors, and it often requires experimentation to determine which data combination will be the best predictor of breakdowns or machine function​.

A cross-functional team of data scientists and machine maintenance specialists work together to determine the factors most indicative of tracking machine function or malfunction.

These teams hypothesize about the combinations of data that might be the best maintenance indicators and use multiple iterations of data combinations and different algorithmic approaches to arrive at a solution that performs better than previous non-ML or DL maintenance procedures.

The decision of which machines to focus their maintenance efforts on is based on a variety of factors, including how many of a particular machine the company operates, the cost of failure of that machine, and the ease with which sensors, PLC, or other data could be used to predict the failure of this machine​.

Challenges and limitations

However, note that the effectiveness of predictive maintenance is only as good as the data used to train the algorithms. Successful implementation requires a well-designed data collection strategy that captures all relevant information about the manufacturing process.

Moreover, even two identical pieces of equipment can have unique patterns of data and thus require unique calibration and diagnosis. The determination of precisely what data should be used as the diagnostic data stream for a specific piece of equipment is not easy and may require expensive and time-consuming iterations. As a result, some firms may discover that, for some equipment, non-ML or DL maintenance is more reliable​.

Quality Control

Traditionally, quality control in manufacturing has relied on machine vision systems. In this setup, human experts decide which features (e.g., edges, curves, color patches) are important for a given problem and create a rule-based system for quality inspection​​.

However, with evolving manufacturing needs and the increasing complexity of products, traditional machine vision methods have proven inadequate.

One example is that it's often ineffective in situations where the difference between good and bad products is hard to detect, such as slight variations in bottle caps that could cause the beverage to spill out during the manufacturing process​.

In contrast, the new breed of deep learning-powered quality inspection software learns from the data it is fed. It doesn't rely on explicit rules defined by human experts. Instead, it learns which features are important by themselves, creating implicit rules that determine the combinations of features that define quality products.

This shifts the burden of quality inspection from human experts to machines, with humans simply collecting the data for training the deep learning model​.

The effectiveness of deep learning in quality control is highly dependent on data. For example, deep neural networks (DNNs) can be trained to recognize specific classes of objects, such as good or bad ventilator valves.

But a challenge arises when the product line changes or a new type of defect appears. The deep learning model needs to be retrained with balanced data - an equal number of images of good and defective products. Given that modern manufacturing has meager defect rates, obtaining a sufficient number of images of defective products can be time-consuming and complex​.

To overcome this challenge, a new category of DNNs, known as lifelong deep neural networks (L-DNNs), is gaining traction. These systems learn rules in a more flexible way, allowing new rules to be learned without even stopping the operating system. L-DNNs separate feature training from rule training and are able to add new rule information on the fly. They still learn features slowly using a large and balanced dataset but don't need images of all known defects, making the model creation more efficient​.

In terms of case studies, I found a few examples, but I was unable to provide a detailed review due to technical difficulties. However, it's worth noting that L-DNNs are being applied in real-world manufacturing scenarios. These models can learn rules from small sets of new data and treat each new defect as an anomaly rather than a rule.

This allows them to adapt quickly to changes in the production line without requiring a complete retraining of the system.

In conclusion, machine learning, particularly deep learning, has brought significant advancements to quality control in the manufacturing industry. It's improving inspection speeds and reducing costs while providing a flexible and adaptive approach to handling the ever-evolving demands of modern manufacturing.

Machine learning technology can analyze data from every layer of an enterprise to provide both high-level and incredibly granular forecasting for demand, delivery, customer behavior, and forward and reverse supply flow​.

In 2020, the worldwide predictive analytics software market was valued at over $5 billion. By 2028, that figure is expected to surge to $41.5 billion. The overall value of DL and machine learning's impact on global supply chain efficiency has been estimated to be between $1.2 and $2 trillion.

This highlights the immense potential for return on investment from incorporating machine learning into supply chain operations​.

Every stage of the supply chain faces volatile conditions, and brittleness anywhere in a supply or distribution network can cripple businesses when markets fluctuate.

Suboptimal production processes, unplanned downtime, shifts in customer-supplier relationships, resource scarcity, and massively disruptive events can be logistical nightmares for the unprepared.

Companies that still depend on outdated forecasting methods cannot get the insights they need to respond constructively. Incorporating machine learning in supply chain design redefines what's possible in terms of transparency, planning, and, ultimately, minimizing losses while identifying opportunities​.

Route Optimization

In the world of logistics, route optimization plays a crucial role in ensuring the efficient delivery of goods and services. It involves identifying the most efficient routes that combine time, distance, and resources to deliver packages effectively.

Despite the crucial role of route optimization, traditional approaches often struggle to adapt to dynamic factors and utilize the potential of data-driven decision-making.

Traditional route optimization has relied on methods such as hand-drawn maps, trial-and-error techniques, and manual planning.

However, these methods are fraught with limitations. They often fail when managing dynamic variables, such as heavy traffic, bad weather, and road closures. Managing multiple drivers, delivery windows, and customer preferences also poses significant challenges.

As a result, the output of these traditional methods is often inefficient routes that lead to higher fuel costs, longer delivery times, and dissatisfied customers​.

Machine learning route optimization provides real-time adjustments, management of dynamic factors, and utilization of historical and real-time data. With the ability to assess both historical and real-time data, identify patterns, and make accurate predictions, machine learning algorithms can optimize routes more effectively than ever before.

They can handle complicated data, adjust to changing conditions, and assist in making data-driven decisions​​.

Several techniques are utilized in machine learning for route optimization, including:

  1. Clustering algorithms: Clustering algorithms work by analyzing a set of locations and classifying them according to their similarities. These algorithms assist in ML route optimization by minimizing unnecessary detours and reducing travel time by grouping all of the stops with similar characteristics​1.
  2. Genetic algorithms: Genetic algorithms mimic the process of natural selection to find optimal solutions. They are used in route optimization to find the best routes by iteratively selecting, combining, and varying the solutions.
  3. Reinforcement learning: Reinforcement learning is a type of machine learning where an agent learns to make decisions by interacting with its environment. In the context of route optimization, reinforcement learning can be used to adapt to real-time changes in the environment, such as traffic or weather conditions.
  4. Neural networks: Neural networks are computing systems inspired by the human brain. They can model complex patterns and relationships between inputs and outputs, making them useful for predicting the best routes based on past data.

Through machine learning route optimization, businesses can experience cost savings, increased customer satisfaction, greater operational efficiency, and scalability.

For instance, Amazon's average "click to ship" time was cut by 225% as a result of machine learning, and implementing DL has reportedly helped businesses reduce logistical costs by 15% and boost service levels by 65%, according to McKinsey​.

In conclusion, machine learning plays a transformative role in route optimization, enabling logistics operations to become more efficient, flexible, and effective. With the ability to adapt in real-time and handle complex, dynamic variables, machine learning offers a significant improvement over traditional route optimization methods. Its potential benefits in cost savings, customer satisfaction, and operational efficiency underscore its value in the logistics industry.

Demand Forecasting

Machine learning is rapidly changing the field of logistics, with a particular emphasis on demand forecasting. As global distribution becomes increasingly complex, businesses are feeling the need to modernize their tools for forecasting demand and planning how to meet it.

A survey of supply-chain executives showed that 90% expect to overhaul their planning IT within the next five years, and four out of five expect to use DL and machine learning in the planning process​.

However, implementing these changes is not without challenges. 60% of supply-chain-planning IT implementations take more time or money than expected or don't achieve the anticipated business outcomes.

Therefore, companies must incorporate forward-looking process design, well-defined vendor selection, and an implementation roadmap into the process of adopting new supply-chain-planning IT systems​​.

Despite the potential benefits, a significant majority of enterprises still rely on manual or outdated methods for supply-chain planning. Close to three-quarters of supply-chain functions depend on spreadsheets, and more than half use outdated supply-chain-planning applications.

However, the trend is changing, with 90% of executives planning to implement a new solution in the next five years, and 23% have already done so. When they upgrade, they often add advanced technology capabilities, with 20% of executives having implemented DL and machine learning for some supply-chain-planning activity and another 60% planning to do so in the future​.

Implementation of a new supply-chain-planning system is time-consuming and expensive. On average, companies spend 2.8 years from vendor selection to complete rollout, with the cost varying depending on the complexity of the company's supply chain. This is one of the reasons why companies hang onto older systems, despite the potential benefits of upgrading​.

Successful implementation requires a well-articulated planning-process design. Companies need to understand their objectives and create detailed descriptions of planning activities that a new system will cover.

They should also identify which low-level processes could be automated and where to implement DL for complex tasks, such as forecasting customer demand​.

Vendor selection is another critical aspect of the process, with supply-chain leaders typically evaluating an average of two vendors to ascertain which system best meets their specific planning challenges. The vendor selection process includes a list of business requirements, clear evaluation criteria, and a few "must-have" use cases​.

Finally, a well-defined multiphase implementation roadmap is essential. This roadmap should prioritize testing and rolling out must-have features before adding those that are nice to have and should include all the change-management components needed to get supply-chain planners and other users of the new system involved in the implementation as early as possible​.

Machine Learning in the Energy Sector

Leveraging Machine Learning for Energy Management

Machine learning has exhibited significant potential in the energy sector. Here, it's leveraged to perceive the environment, make decisions, and learn high-dimensional patterns from data to optimize energy management and sustainability.

Deep learning is at the forefront of this movement. It has surpassed the previous state of the art in multiple industries, including the energy sector, demonstrating its potential to create significant business value from raw, high-dimensional data​.

Machine learning comprises three branches, each playing a unique role:

  1. Supervised Learning: Machine learning models use labeled training data to predict the labels of unseen data. This branch is responsible for functionalities such as image recognition and language translation in various sectors.
  2. Unsupervised Learning: These models generate new data without the supervision of labels. They are often used in artistic style transfer and the generation of realistic images.
  3. Reinforcement Learning: Here, the machine learns to select actions based on a reward signal, such as cost or carbon emissions. It is applicable to a wide range of decision-making problems with a reward signal, such as optimizing energy usage or minimizing carbon emissions​.

Machine learning's generalizability, or its ability to adapt and learn across different contexts and problem sets, is a major driving force behind its utility in the energy sector.

For example, a neural network can predict solar power generation from satellite images or dispatch a battery based on grid data. This has opened up new possibilities for energy management and optimization​.

In the energy sector, advances in data analytics, machine learning, and IoT technologies have facilitated the development of smart grids.

These intelligent power systems leverage machine learning to balance supply and demand, optimize energy flows, integrate renewable energy sources, predict system failures, and improve the overall operation and management of energy systems. This enables more efficient use of resources, enhanced grid reliability, and a shift towards more sustainable energy systems​.

In summary, machine learning, particularly through its application in deep learning, is becoming a pivotal tool in energy management. By leveraging machine learning algorithms, the energy sector can enhance efficiency, integrate renewable resources, and better manage energy demand.

However, while machine learning shows great promise in revolutionizing energy management, it's important to note that the potential of machine learning is more latent in industries that are less digitized, such as the energy sector. This suggests that while strides have been made, there is still considerable work to be done in fully integrating and leveraging machine learning within this field​.

Energy Consumption Prediction

Machine learning has been used in a variety of industries to predict energy consumption. For example, in the U.S., electrical, metal, plastic, and food manufacturing are some of the most significant energy-consuming industries.

The U.S. Department of Energy Industrial Assessments Centers (IACs) have conducted audits to track and analyze energy data across these industries and have used statistical and machine learning techniques to draw insights from this dataset collected from 1981 to 2013 (source).

The machine learning models developed from this dataset could be useful in benchmarking the energy consumption of factories and identifying opportunities to improve energy efficiency​.

Various machine learning techniques have been employed for energy consumption prediction, such as Multiple Linear Regression, Random Forest Regressor, Decision Tree Regressor, and Extreme Gradient Boost Regressor. Also, classifier models were developed using Support Vector Machines, Random Forest, K-Nearest Neighbor (KNN), and deep learning.

The results indicated that the Random Forest Regressor was the best prediction technique with an R^2 of 0.869 for regression, and the Random Forest classifier was the best technique with precision, recall, F1 score, and accuracy of 0.818, 0.884, 0.844, and 0.883 for classification, respectively. A sequential Deep learning model also performed competitively with an accuracy of about 0.88 in training and testing after 10 epochs (source).

Smart grids and smart homes have presented new challenges for energy consumption prediction due to the advancements of smart technologies. Machine learning, particularly neural network-based methods, has been successful in energy consumption prediction.

However, limitations exist due to uncertainty in the data and the algorithms' constraints. Machine learning models developed for smart grids need to handle consumption data from thousands of customers, and the inclusion of covariates into these models has been shown to improve accuracy by learning past and future energy consumption patterns.

One model that has shown promise in this regard is the Neural Basis Expansion Analysis for Interpretable Time Series (N-BEATS), which performed better for daily, weekly, and monthly energy consumption predictions based on a large dataset (source).

Renewable Energy Forecasting

The global trend toward a sustainable future has encouraged the penetration of renewable energies into the electricity sector. These renewable energy sources, notably wind, and solar power, present a unique challenge due to their inherent variability and dependence on seasonal and weather conditions, such as temperature, pressure, wind speed, and visibility.

These chaotic conditions can change dramatically from time to time, enforcing difficulties in the scheduling and management of optimal electricity generation and imposing concerns regarding electricity quality and stability​.

To tackle the problems of unreliability and inaccuracies of renewable power forecasting models, various research studies have been employed. These include persistence models, physical models, statistical models, artificial intelligence (AI) models, and hybrid models consisting of a combination of two or more of these models.

Among these, machine learning-based models have gained considerable interest. Unlike statistical models, ML techniques can capture the non-linearity in power data and can be applied for several purposes with only minor modifications. Therefore, because of their flexibility and compatibility, ML forecasters could outperform and alternate conventional forecasters​.

There are several types of ML models used for renewable energy forecasting:

  • Artificial Neural Networks (ANNs): ANNs are widely used in renewable energy forecasting due to their ability to learn complex patterns from data. They can model non-linear relationships and are robust against noise in the data. The key challenge with ANNs is determining the optimal architecture, including the number of layers and neurons, which requires significant computational resources.
  • Recurrent Neural Networks (RNNs): RNNs are a type of neural network that is especially effective at handling sequential data, making them ideal for time-series forecasting problems like renewable energy forecasting. Like ANNs, they can learn complex patterns, but they also have the added ability to maintain a form of "memory" of past data points.
  • Support Vector Machines (SVMs): SVMs are another powerful machine learning technique used in renewable energy forecasting. They are able to model complex non-linear relationships through the use of different kernel functions.
  • Extreme Learning Machines (ELMs): ELMs are a type of feedforward neural network with a single layer of hidden nodes, where the weights are initialized randomly and don't need to be adjusted during training. This leads to much faster training times compared to traditional neural networks. They are well-suited to tasks like renewable energy forecasting, where speed is important.

In addition to these, special attention is paid to the metaheuristics accompanied by these ML models. Metaheuristics are high-level problem-independent algorithmic frameworks that provide a set of guidelines or strategies to develop heuristic optimization algorithms. They are used for tuning ML model parameters and optimizing the network parameters of the ML systems​.
