A Geometry-Based Capacity Theory for Finite-Feature Associative Memory

Jianhai Zhang, Donghao Zhang, Pattarawut Charatpangoon et al. · 2026

We develop a geometry-based capacity theory for exact-key retrieval in compressed finite-feature Hebbian associative memory. For random or approximately isotropic values, retrieval interference separates into finite-feature noise, which decreases with feature dimension, and structural interference, which is determined …

PredRA: Fast Medical Image Translation by Deterministic Component Extraction and Controlled Stochastic Refinement

Jianhai Zhang, Pattarawut Charatpangoon, Donghao Zhang et al. · 2026

Strongly paired medical image translation contains a substantial component that can be predicted directly from the source. The current reality is that pure deterministic prediction can smooth away fine detail, while generative models can recover detail but may also introduce unnecessary or potentially harmful variation …
