V-Align: Visual Forced Alignment via Phoneme to Video Optimal Path Traversal

V-Align is proposed, a structured framework that formulates VFA as an optimal mono-tonic path traversal problem over a frame–phoneme compatibility lattice and learns a soft traversal posterior and recovers discrete boundaries via dynamic programming.

A Plug-in Interpretation of Conditioning in Score-Based Diffusion Models

A conditioning mechanism for diffusion models based on multi-speed joint diffusion of the target and the condition learns an unconditional joint score network and enforces conditioning at inference via a plug-in correction term, and derives explicit conditional reverse-time SDEs and approximate probability-flow ODEs.
