What is Artificial Intelligence (AI)?

Artificial Intelligence (AI) is a branch of computer science that is focused on developing computer systems that can carry out functions that usually require human intelligence. For example, understanding natural language, language translation, identifying patterns and images (computer vision), decision-making, and problem-solving.

AI systems are made up of multiple layers of algorithms, created to mimic human cognition, this makes it possible for them to learn and adjust as they process new data. This quality differentiates AI from standard computer programs, making it perfect for the detection and alleviation of fraudulent activities.

AI has the potential to revolutionize various industries by automating processes, improving efficiency, and enabling new capabilities and innovations.

What is Machine Learning (ML)?

Machine Learning (ML) is a form of Artificial Intelligence (AI) that is focused on designing and constructing algorithms that enable computer systems to learn from data and improve their performance without special programming.

It is a subset of artificial intelligence, which enables machines to automatically learn and adapt from experiences without being explicitly programmed.

By feeding and analyzing vast data sets, Machine Learning systems draw from different forms of statistical, probabilistic, and optimization techniques, which enables them to find structures in data and form intelligent predictions or decisions.

Differences between Artificial Intelligence (AI) and Machine Learning

Artificial Intelligence (AI) and Machine Learning (ML), are commonly used interchangeably in computer science, but they differ in the following ways;

AI is the ability of a computer system or machine to mimic the cognitive abilities of humans such as problem-solving, learning, and pattern recognition. In this context, AI systems are designed to behave intelligently like humans. Whether it’s voice assistance, image recognition, or even predicting consumer behaviors, AI plays a vital role in facilitating these applications.

While Machine Learning is a subset of AI. AI is involved in the broader notion of machines performing tasks smartly, ML is the specific use of algorithms and statistical models to assist machines in learning autonomously. Some examples of how ML mimics the functioning of the human brain to learn from patterns or features in vast datasets are Deep learning and neural networks.

In the context of fraud management, AI uses its intelligence to mimic human judgment and detect potentially fraudulent activities, while ML gathers data from past fraudulent instances, and uses it to improve its ability to detect anomalies and prevent fraud.

Generally, Al and ML have similar goals but different roles and functions that can be enhanced to improve fraud detection and prevention systems.

Role of AI in Fraud Detection

AI in fraud detection depends on computer vision and natural language processing to detect and alleviate fraud. Generally, it performs the following functions:

1. Real-time Transaction Monitoring: Unlike human analysts, AI systems are capable of processing large amounts of data quickly and accurately. Thereby giving immediate feedback and alerts for fraudulent activities.

2. AI Patterns: AI algorithms are also capable of detecting patterns like unusually high spending, unauthorized access from multiple accounts, and analysis of large data breaches to proactively protect user accounts.

3. Biometrics: The combination of AI and biometric authentication, like fingerprints to unlock your phone or the use of face identification, adds an additional layer of security for consumers’ online devices, this makes it more difficult for fraudsters to collect personal data.

4. Detection of Abnormal Behavior: AI can analyze the transaction history, location data, and other factors of the user and use the information collected to build profiles. When transactions different from the typical behavior of the user are observed, they may be flagged for review.

5. Predictive Analysis: AI systems for fraud detection are capable of predicting a complex pattern that might not be noticed by a traditional rule-based system. Thereby improving the rate of detection and reducing cases of false negative transactions.

6. Reduced Human Error: Unlike traditional detection methods, the risks of human errors are more reduced in the Al system, this makes the process of fraud detection more effective.
