FastFLUX: Pruning FLUX with Block-wise Replacement and Sandwich Training

AAAI 2026technical

Recent advancements in text-to-image (T2I) generation have led to the emergence of highly expressive models such as diffusion transformers (DiTs), exemplified by FLUX. However, their massive parameter sizes lead to slow inference, high memory usage, and poor deployability. Existing acceleration meth

Few-Shot Class-Incremental Learning via Class-Aware Bilateral Distillation

CVPR 2023poster

Few-Shot Class-Incremental Learning (FSCIL) aims to continually learn novel classes based on only few training samples, which poses a more challenging task than the well-studied Class-Incremental Learning (CIL) due to data scarcity. While knowledge distillation, a prevailing technique in CIL, can al…
