D2 Prune: Sparsifying Large Language Models via Dual Taylor Expansion and Attention Distribution Awareness

AAAI 2026technical

Large language models (LLMs) face significant deployment challenges due to their massive computational demands. While pruning offers a promising compression solution, existing methods suffer from two critical limitations: (1) They neglect activation distribution shifts between calibration data and t

HitKV: Activation Frequency Knows Which Tokens Are Important

AAAI 2026technical

The demand for long-context processing in large language models (LLMs) continues to escalate alongside rapid advancements in their capabilities. However, the intermediate attention keys and values (KV cache) employed to avoid re-computations, also grow linearly with sequence length, far exceeding th

Ultra-fast robust compressive sensing based on memristor crossbars

ICASSP 2017accepted

In this paper, we propose a new approach for robust compressive sensing (CS) using memristor crossbars that are constructed by recently invented memristor devices. The exciting features of a memristor crossbar, such as high density, low power and great scalability, make it a promising candidate to p…
