Variational Flow Maps: Make Some Noise for One-Step Conditional Generation

ICML 2026poster

Flow maps enable high-quality image generation in a single forward pass. However, unlike iterative diffusion models, their lack of an explicit sampling trajectory impedes incorporating external constraints for conditional generation and solving inverse problems. We put forth _Variational Flow Maps_,…

Aesthetic Post-Training Diffusion Models from Generic Preferences with Step-by-step Preference Optimization

CVPR 2025poster

Generating visually appealing images is fundamental to modern text-to-image generation models. A potential solution to better aesthetics is direct preference optimization (DPO), which has been applied to diffusion models to improve general image quality including prompt alignment and aesthetics. Pop…

Truth-to-Estimate Ratio Mask: A Post-Processing Method for Speech Enhancement Direct at Low Signal-to-Noise Ratios

ICASSP 2020accepted

This study proposes a bi-directional recurrent neural network (Bi-RNN) post-processing method for speech enhancement (SE) at low signal-to noise ratios (SNR). Current speech enhancement solutions performed badly under low SNR situations. Loizou and Kim proposed a solution to reduce speech distortion…
