Prefilling-dLLM: Predictive Prefilling for Long-Context Inference in Diffusion Language Models

arXiv:2606.10537v2 Announce Type: replace Abstract: Diffusion large language models (dLLMs) re-encode the entire prefix at every denoising step, causing recomputation that scales quadratically with...

TopGQ: Fast GNN Post-Training Quantization Leveraging Topology Information

TopGQ is a post‑training graph neural network (GNN) quantization framework that reduces quantization overhead by using dual‑axis scale absorption, which merges one dimension into the adjacency matrix for activation quantization. It also introduces TopPIN, a proxy for nodes’ local structure, to group nodes with similar topology during quantization. Experiments demonstrate that TopGQ cuts quantization time by an order of magnitude while maintaining accuracy.
