New PQMass method probabilistically assesses generative model quality

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced PQMass, a new method for evaluating generative models by comparing probability distributions. This likelihood-free approach assesses model quality, novelty, and diversity without making assumptions about the true distribution or requiring auxiliary model training. PQMass divides the sample space into regions and uses chi-squared tests on bin counts to determine the probability that samples come from the same distribution, proving effective across various data modalities and dimensions, and scaling to moderately high-dimensional data.

    PQMass: Probabilistic Assessment of the Quality of Generative Models using Probability Mass Estimation

    arXiv:2402.04355v4 Announce Type: replace-cross Abstract: We propose a likelihood-free method for comparing two distributions given samples from each, with the goal of assessing the quality of generative models. The proposed approach, PQMass, provides a statistically rigorous met…
