FAEDKV: Infinite-Window Fourier Transform for Unbiased KV Cache Compression

EMNLP 2025

The efficacy of Large Language Models (LLMs) in long-context tasks is often hampered by the substantial memory footprint and computational demands of the Key-Value (KV) cache. Current compression strategies, including token eviction and learned projections, frequently lead to biased representations—

Pruning Weights but Not Truth: Safeguarding Truthfulness While Pruning LLMs

EMNLP 2025

Neural network pruning has emerged as a promising approach for deploying LLMs in low-resource scenarios while preserving downstream task performance. However, for the first time, we reveal that such pruning disrupts LLMs’ internal activation features crucial for lie detection, where probing classifi

Quantized but Deceptive? A Multi-Dimensional Truthfulness Evaluation of Quantized LLMs

EMNLP 2025

Quantization enables efficient deployment of large language models (LLMs) in resource-constrained environments by significantly reducing memory and computation costs. While quantized LLMs often maintain performance on perplexity and zero-shot tasks, their impact on truthfulness—whether generating tr

When Truthful Representations Flip Under Deceptive Instructions?

EMNLP 2025

Large language models (LLMs) tend to follow maliciously crafted instructions to generate deceptive responses, posing safety challenges. How deceptive instructions alter the internal representations of LLM compared to truthful ones remains poorly understood beyond output analysis. To bridge this gap,
