The problem FraudLert - The Ultimate Fraud Saver SaaS solves
Building a fraud detection system for identifying fraudulent activities in financial transactions involves several complex challenges and requires a multidisciplinary approach. Here’s an overview of the problem statement, the problems faced during development, and the solutions devised to overcome these challenges:
Problem Statement
The goal is to create a comprehensive fraud detection system capable of identifying fraudulent activities within financial transactions. The system should utilize machine learning models to detect anomalies and fraud patterns, provide a user interface for monitoring transactions and alerts, integrate backend services for data processing and analysis, ensure real-time detection and alerting, and include features for investigating and managing fraud cases.
Challenges we ran into
- Problem: Financial transactions data is massive, noisy, and often incomplete. The volume of data can overwhelm systems, and the quality can affect the model's accuracy.
-
Solution: Data preprocessing techniques such as cleaning, normalization, and imputation were implemented to enhance data quality. Scalable data storage solutions like cloud-based databases were used to handle the large volumes of data efficiently.
-
Problem: Identifying the right features that can distinguish between legitimate and fraudulent transactions is challenging.
-
Solution: Domain experts collaborated with data scientists to identify key indicators of fraud. Techniques such as feature selection and extraction were used to create a robust set of features for training the models.
-
Problem: Selecting the right machine learning models that can accurately detect fraud while minimizing false positives is critical. Performance can vary greatly based on the model used.
-
Solution: A combination of models such as Random Forests, Gradient Boosting
