EleutherAI has released a research update on their tyche library, designed to measure the local volume of neural networks. This metric estimates the probability of sampling a network with similar behavior to a trained one, potentially useful for detecting unusual model behavior. However, experiments on the POSER benchmark showed that tyche's weight perturbation method was not competitive with POSER's activation perturbation method for detecting model misalignment. AI
