Alignment-Guided Score Matching for Text-to-Image Alignment in Diffusion Models

Researchers propose Alignment-Guided Score Matching (AGSM), a reward-free post-training method that improves text-to-image alignment in diffusion models by integrating contrastive guidance into the score-matching objective. The approach addresses failure cases like over-counting and repetition in existing methods, achieving 35% improvement in counting accuracy while remaining compatible with major diffusion model architectures.

Constant-Target Energy Matching: A Unified Framework for Continuous and Discrete Density Estimation

Researchers introduce Constant-Target Energy Matching (CTEM), a unified framework for density estimation that handles continuous, discrete, and mixed-variable data types within a single objective function. CTEM replaces traditional density-ratio regression with a bounded energy-difference transform, eliminating instability issues and partition-function estimation requirements while delivering improved sample quality across diverse data domains.

Manifold Aware Denoising Score Matching (MAD)

Researchers propose Manifold Aware Denoising Score Matching (MAD), a computational method that improves machine learning distribution modeling on manifolds by decomposing score functions into known and learned components. The technique reduces computational burden while maintaining efficiency for complex mathematical distributions including rotation matrices.
