Machine learning is increasing in usage across several industries, from manufacturing and engineering to retail and marketing. While ML has many applications, the average person has yet to understand it fully.

In simple terms, ML allows software applications tocontinuously improve over timeand better predict outcomes with little to no human intervention. A machine learning algorithm is a program the AI system uses to conduct a task. Their algorithms can often analyze historical datasets to predict valuable outcomes.

ML is the foundation of predictive analytics, which is a trend taking the business world by storm. However, they can also train machine learning algorithms for other purposes like fraud recognition.

Learn more about fraud detection, why it’s essential to use machine learning to detect fraud, industries that benefit from this practice, and some tips for data scientists training these ML algorithms.

According to a press release, the Federal Trade Commission receivedaround 2.8 million fraud reportsfrom consumers last year. That’s an increase of 70% from the previous year in the United States alone.

Some of the most commonly reported types of fraud include:

Other types of fraud are mortgage scams, pump and dump schemes, false insurance claims, corporate fraud, identity theft, and more. People lose billions of dollars yearly due to scams, fraud, and identity theft.

While no one wants to become a victim of fraud, it’s not surprising to hear how common it is. With cyberattacks and data breaches becomingmore frequent and sophisticated, it’s easy for malicious actors to get their hands on sensitive and personal data.

Recognizing fraud is not a simple task, which is why more businesses are exploring the option of using ML for fraud detection. Some consider machine learning one of the best technologies to use for financial fraud detection.

ML for fraud detection works by analyzing massive amounts of historical data — namely consumer trends, behavior, and transaction methods. Machine learning algorithms can parse through data much more efficiently and accurately than a human analyst.

As a result, these systems can recognize any slight deviation from these learned patterns and alert users. Fraud detection using an ML algorithm works in real-time, monitoring transactions and flagging them for review if anything suspicious occurs. This tracking is especially crucial around the holidays and for seniors — two instanceswhere fraud rates increasenoticeably.

Many machine learning algorithms for fraud recognition are self-learning, including the Amazon Web Services Fraud Detection Using Machine Learning architecture. The self-learning capability allows the ML model to automatically adapt to new fraud patterns.

Fraud-detection systems arealso highly cost-effectivefor companies. Organizations can cut costs by investing in an ML model and reduce or eliminate the need for human data analysts. The system can analyze data in milliseconds, so human workers are not overburdened with manually checking any new data inputs.

What are some of the primary industries that would benefit from using ML models for fraud recognition and detection? Examples may include:

This is by no means an exhaustive list. Still, it does provide a glimpse into what types of applications ML has for advanced fraud detection.

Suppose you’re a data scientist or a professional working with information daily. In that case, you may find yourself working on a project that uses machine learning for fraud detection. In that case, it’s vital to know some best practices and tips to handle this type of ML project.

Here are some tips for data professionalswho may train machine learning algorithmsto recognize fraud patterns. Practitioners must:

The number of use cases for ML could increase, especially regarding how businesses can use it to prevent cybercrime, scams, and other fraudulent activities.

Businesses worldwide have already used machine learning and other data-science practices to prevent financial fraud. ML is a promising, innovative, and invaluable tool more companies should consider using — especially if fraud is a significant challenge they face.

As ML evolves, it will expand its capabilities and better recognize fraud patterns. It will be interesting to see what industries use models for fraud detection and if it will reduce the number of reported fraud cases.
