Key Points

  • The article describes extending a hybrid neural network with a differentiable rule-learning module to automatically extract IF-THEN fraud rules during training.
  • Using the Kaggle Credit Card Fraud dataset (fraud rate 0.17%), the model learned interpretable rules.
  • The work demonstrates that neural networks can discover human-readable rules, potentially improving interpretability in fraud detection.
  • The post is published on Towards Data Science, linking to the original article.

Most neuro-symbolic systems inject rules written by humans. But what if a neural network could discover those rules itself?

In this experiment, I extend a hybrid neural network with a differentiable rule-learning module that automatically extracts IF-THEN fraud rules during training. On the Kaggle Credit Card Fraud dataset (0.17% fraud rate), the model learned interpretable rules such as:
