Thought-Aware KV Cache Compaction for Reasoning via Adaptive Attention Matching

Yang Liu, Bin Chong, Chongyang Zhang +3

Reasoning language models generate lengthy chain-of-thought (CoT) sequences whose key-value (KV) cache grows linearly and becomes a memory bottleneck during decoding. Existing comp…

SAHG: Sector-Anisotropic Hyperbolic Graph Model for Social Bot Detection

Hanning Lu, Yingguang Yang, Jinwei Su +8

LLM-driven social bots can generate fluent, human-like text, reducing the discriminative advantage of content-based detection alone. However, coordinated campaigns still leave rela…
