Beta Shapley: a Unified and Noise-reduced Data Valuation Framework for Machine Learning

Beta Shapley: a Unified and Noise-reduced Data Valuation Framework for Machine Learning

This repository provides an implementation of the paper Beta Shapley: a Unified and Noise-reduced Data Valuation Framework for Machine Learning accepted at AISTATS 2022 as oral presentation. We propose a noise-reduced data valuation method, Beta Shapley, which is powerful at capturing the importance of data points.

Quick start

We provide a notebook using the Covertype dataset. It shows how to compute the Beta Shapley value and its application on several downstream ML tasks.
