ESR-HGNN: Eliminating Semantic Redundancy for Efficient Mini-Batch HGNN Inference

This work proposes a redundancy-aware HGNN sampling paradigm that leverages a metapath trie to reuse traversal paths, effectively eliminating redundant memory accesses and introduces a reusability-driven metapath grouping technique that optimally clusters metapaths to maximize reusable traversal paths within hardware channels, enhancing efficiency in scenarios with semantic parallelism.

DraftExpert: Expansion-Aware Self-Speculative Decoding for End-Device MoE Inference

DraftExpert is proposed, an expansion-aware self-speculative decoding framework for expert-offloaded MoE inference that improves decode throughput by 1.45x on average, raises draft acceptance to 84~87%, and achieves 86~88% prefetch hit rates.
