EMCES: How Episodic Memory Guides Controllable Sample Synthesis to Boost Reinforcement Learning

The paper introduces EMCES, a method that injects episodic memory into controllable diffusion models and uses a hash‑based state representation to generate high‑value synthetic samples, dramatically improving sample efficiency and downstream reinforcement‑learning performance while cutting storage and time costs.

How Flow‑GRPO Boosts Image Generation Accuracy to 95% with Online Reinforcement Learning

Flow‑GRPO introduces online reinforcement learning into flow‑matching models by converting deterministic ODE sampling to stochastic SDE sampling and reducing denoising steps, raising SD‑3.5‑Medium's GenEval accuracy from 63% to 95%—surpassing GPT‑4o—and demonstrating strong gains in complex composition, text rendering, and human‑preference alignment across multiple generative tasks.
