Vendi score

anchor

Diversity measure computed as the effective number of distinct items in a set, from the eigenvalues of a similarity matrix.

Note

anchor found by search and checked against this entry: "The Vendi Score: A Diversity Evaluation Metric for Machine Learning", defined as the exponential of the Shannon entropy of the eigenvalues of a similarity matrix, which is what this entry describes

Findings

• IC-023Local scaling, rank, and complexity of Stable Diffusion correlate with generation aesthetics, diversity, and memorization [eval]
• IC-024Reward model trained on local scaling of Stable Diffusion can guide generation to increase diversity and aesthetic scores [eval]
