Enhancing Black-Box Model Interpretability
Influence functions are critical for understanding how individual training data points impact black-box AI models. Traditional methods are hindered by high computational costs and inaccurate estimations, especially with large-scale models. Our advanced sampling strategies provide a more efficient and accurate way to derive these insights, making black-box models more transparent and amenable to ethical oversight. This directly supports the need for greater explainability in hyper-scale AI systems, addressing concerns about AI deception and promoting alignment with human values.
