📰 Medium · Programming

Learn how to fix a fraud detection model with high false negatives using AutoEncoder anomaly scoring, Gradient Boosting ensembles, and SHAP explainability

advanced Published 1 May 2026
Action Steps
  1. Build an AutoEncoder model to detect anomalies in transaction data
  2. Configure a Gradient Boosting ensemble to improve model accuracy
  3. Apply SHAP explainability to understand model predictions and identify areas for improvement
  4. Test the model using real-time Kafka streaming to evaluate its performance
  5. Compare the results with the previous model to measure the reduction in false negatives
