FREMONT, CA: While machine learning may appear to be a difficult concept to grasp, it is a lot simpler than one might imagine. Take a look at what goes into creating a machine learning-based system and the most prevalent types of Machine Learning (ML) models used in payment fraud detection in this article.
Building a Machine Learning Payment Fraud Model
Firms must first compile a dataset before they proceed. The data points utilized will almost always need to be manually labeled as real or fraudulent. The business's archive of past payments, which the security team has already marked, will make for a perfect dataset. The more data one has to train the neural network on (and the higher the quality), the more accurate and efficient the system will be.
Introduction of Features
The next step is to introduce features, which are data elements that describe consumer behavior and notifying the business when something is awry with the transaction. The following are the most typical features in payment processing:
Having a huge, pre-prepared corpus of fraudulent payment features will make it much easier for the system to detect fraudulent payments right away.
After adding the features, one will need to train the algorithm using a set of historical data. They will have a finalized model that can start detecting fraudulent payments once the training step is completed. The system will be better and more accurate if the training set is of greater quality.
The security team will need to monitor the system during the initial stages of its operation to ensure that it is functioning correctly. A good security team will also be able to keep track of all algorithm faults and mistakes. These will be labeled and added to the dataset for training a new version of the model. As a result of these measures, the system will continue to improve over time.
