In general, fraud can be defined as some illegal or criminal thing done by any person who intended to deceive in financial organizations or personal profit. So the processes of analyzing such illegitimate transactions done by anyone like buyer or customer are caught and only the legal transactions are allowed to be made. As fraud is increasing in day to day life so to analyze frauds that are occurring in the organizations or companies these frauds are analyzed using some quantitative science to understand the fraud, through BI (Business Intelligence), and then we have to develop effective fraud detection solutions through data science.
To carry on the fraud analytics we have to detect the frauds to find the proper solutions to overcome these illegal activities. Fraud detection is a process having different sub-processes to carry on, for detecting activities that take place to prevent money or credentials from being illegally known to another person. Machine learning is a scientific discipline that explores the construction and study of algorithms that can learn from data. Such algorithms operate by building a model from example inputs and using that to make predictions or decisions, rather than following strictly static program instructions. Machine learning is closely related to and often overlaps with computational statistics; a discipline that also specializes in prediction-making.
Through this training, we are going to guide you through the process of understanding the concept of fraud detection in credit payments using a case study. We have used Kmeans and hierarchical clustering for understanding the data and also used other visualization techniques and methods to compare and understand the flow of Data.
The main aim of this course is to provide a wide understanding of fraud detection analytics and students or professionals will also get to understand the robust internal controls and risk management system in organizations.
for detecting fraud machine learning concepts and algorithms are required to understand. In this section, we detect fraud in credit card payments or transactions using installation packages for fraud detecting. In this section, algorithms like Kmeans, hierarchical clustering for understanding the data. This section, includes topics on cust ranking that explains risk analysis, rank functions, RHS constraints, VRS, CRS efficiency, etc. You will first be introduced to the banking system which includes loan status grades, beta value, predict value, performance values, etc. In this section, you will also learn about logistic regression algorithms to implement them in a project.
