Research: Non-maximal probability mapping impacts S-JEPA encoder representations

A research paper investigates the impact of mapping non-maximal probabilities to Gaussian Mixture Model (GMM) components within the S-JEPA encoder. The study found that the specific mapping of these probabilities, not just their numerical values, significantly influences the learned encoder representations. Experiments demonstrated that preserving the original mapping of non-maximal probabilities led to better recovery of GMM tails and improved spectral dynamics, suggesting this structural information is crucial for representation learning.

    Does Mapping Non-Maximal Probabilities to GMM Components Matter for S-JEPA Encoder Representations?

    S-JEPA uses soft Gaussian mixture model (GMM) posteriors instead of hard cluster labels to preserve uncertainty. It remains unclear whether the probability values alone are sufficient, or whether it also matters which GMM components receive the non-maximal probabilities. We test …
