LSH-KV: Efficient KV Cache Retrieval for Long-Context LLM Inference via Locality-Sensitive Hashing

As large language models increasingly support long-context inference, the computation and memory access overhead of attention and KV caches have become critical bottlenecks for inference latency and system scalability. Existing approaches mitigate these costs through KV cache dropping, approximate attention, or system-...

Efficient Simple Temporal Cycle Enumeration on Large Graphs with Lightweight Preprocessing

This work introduces a novel edge-centric framework that treats temporal edges as the core units of exploration and eliminates redundant temporal checks, and extends this framework to dynamic settings by introducing an efficient incremental update algorithm that selectively identifies affected paths only.

Efficient Simple Temporal Cycle Enumeration on Large Graphs with Lightweight Preprocessing

Temporal cycles are fundamental patterns in graphs, with important applications in finance, security, and neuroscience. In this work, we study the Simple Temporal Cycle Enumeration (STCE) problem, which aims to enumerate all simple cycles with strictly increasing timestamps within a given time window. However, existing...
