Faithful and Fast Influence Function via Advanced Sampling
NeutralArtificial Intelligence
A recent study discusses the challenges of using influence functions to explain the impact of training data on black-box models. While influence functions can provide insights, calculating the Hessian for an entire dataset is often too resource-intensive. The common practice of sampling a small subset of training data can lead to inconsistent estimates, highlighting the need for more reliable methods. This research is important as it addresses a significant limitation in machine learning interpretability, paving the way for more effective and efficient approaches.
