Data Banzhaf

The Banzhaf power index is a power index defined by the probability of changing an outcome of a vote where voting rights are not necessarily equally divided among the voters. Data Banzhaf uses this notion to measure data points' "voting powers" towards algorithmic decisions.

Trustworthy AI Relevance

This metric addresses Data Governance & Traceability and Robustness by quantifying relevant system properties. Data Banzhaf assigns an influence/power score to individual training examples by measuring how often a data point changes a model’s utility when added to subsets of the dataset. This directly supports Data Governance & Traceability by providing an auditable signal of which records drive model behavior (useful for provenance, accountability, and targeted data removal/compensation).
