Equilibrium Training of Energy-Based Models with Parallel Trajectory Tempering

Energy-Based Models (EBMs) provide an interpretable framework for generative modeling of scientific data, but poor Markov Chain Monte Carlo mixing often limits their reliability. We introduce a training algorithm based on Parallel Trajectory Tempering (PTT), which exploits the continuity of the optimization path to maintain equilibrium sampling throughout learning.

Noise-Debiased Thermodynamic Variance for Local Learning Coefficient Probes

The paper introduces the Shift‑Invariant Variance Estimator (SIVE) to remove same‑state noise from thermodynamic variance calculations in neural‑network training. SIVE provides an unbiased estimate of path variance without requiring Markov chain Monte Carlo stationarity, and it reveals a reproducible mid‑training trough and rebound in MNIST MLP trajectories that raw variance masks. Experiments across multiple localization scales confirm that SIVE captures a large portion of observation noise and satisfies an early‑drop/late‑rise criterion in most trajectory‑scale pairs.
