- Unsupervised Learning: The model analyzes unlabeled data to identify anomalies or unusual patterns that might indicate fraud. This approach is particularly useful for detecting new fraud tactics that have yet to be encountered.
Data Quality and Diversity
The quality and diversity of the training data heavily influences the effectiveness of ML models. High-quality data is accurate and well-structured, while diverse data encompasses various fraud scenarios and demographics. This diversity helps models generalize better across different contexts, enhancing their ability to detect fraud effectively.
Feature Engineering
Feature engineering involves selecting and refining key attributes from the data to improve the accuracy of ML models. This includes:
- Extracting Relevant Features: Identifying which data points are most indicative of fraud.
- Transforming Features: Modifying data to enhance clarity and relevance.
- Creating New Features: Developing new data points that can highlight suspicious patterns.
