Counterfactual WOA and GA
- Interpretation of Black-Box Model with Counterfactual Instance generated by Metaheuristics
- used Whale Optimization Algorithm and Genetic Algorithm
- Counterfactual
- Generate the most similar input data (features) with the most different predictions
- the more changes (of input features), the more important
- Objective Function
- minimize difference between a sample (which we want to interprete) features and a generated one
- maximize difference between a sample (which we want to interprete) targets and a generated one
- I used RMSE but you can use Cosine Similarity considering your input data distribution
- N_features : 10
- Not Informative Features : 4, 6, 9 (index)
- N_targets : 3
- This data was generated by using sklearn's make_regression function
