Efficient Difficulty-Aware Dynamic Routing for Diffusion-Based Real-World Image Super-Resolution

A Difficulty-aware Dynamic Routing (DDR) strategy that overcomes the rigid, one-size-fits-all processing paradigm for Real-ISR approaches, and builds a set of Real-ISR networks with varying model capacities by modulating the spatial downsampling ratio of the VAE in the SD backbone.

Why Does Post-Training Quantization Work?

Comparing full-precision and quantized forward passes, and identifying two mechanisms that characterize pretrained quantization robustness, these mechanisms explain why quantization error that passes through numerous layers can still produce only small output changes, and are verified across models and quantization set...
