Diffusion Fine-tuning with Rewarded Moment Matching Distillation

Alexis Jacq, Guillaume Couairon, Valentin De Bortoli +3

Distillation and Reinforcement Learning (RL) fine-tuning are the primary pillars of diffusion post-training. While traditionally studied in isolation, the interaction between these…

ArchesClimate: Probabilistic Decadal Ensemble Generation With Flow Matching

Graham Clyne, Guillaume Couairon, Guillaume Gastineau +2

Internal variability is a dominant contributor to the uncertainty of predictions at the interannual to decadal timescale. A typical approach to separating the internal variability…

AsyncPatch Diffusion: spatially-flexible image generation

Samuele Papa, Valentin De Bortoli, Guillaume Couairon +3

Standard diffusion models corrupt an entire sample with a single shared noise level, forcing all spatial regions to follow the same denoising trajectory. We introduce AsyncPatch Di…
