Counterfactual Perturbation

Counterfactual perturbation involves generating hypothetical scenarios by altering existing data points to understand system behavior under different conditions. Current research focuses on applying this technique to improve the robustness and interpretability of machine learning models, particularly in natural language processing and biological systems, using methods like retrieval-augmented generation, differentiable neural networks, and generative models to create and analyze these perturbations. This approach enhances model generalization, reveals spurious correlations, and facilitates more explainable AI by identifying factors driving model predictions, with implications for areas like drug discovery and personalized medicine.
