arXiv:2605.00140v1 Announce Type: new Abstract: We present Activation Residual Hessian Quantization (ARHQ), a post-training weight splitting method designed to mitigate error propagation in low-bit activation-weight quantization.

Key details

  • By constructing an input-side residual Hessian from activation quantization residuals (G_x), ARHQ analytically identifies and isolates error-sensitive weight directions into a high-precision low-rank branch.
  • This is achieved via a closed-form truncated SVD on the scaled weight matrix W G^{1/2}_x .
  • Experimental results on Qwen3-4B-Thinking-2507 demonstrate that ARHQ significantly improves layer-wise SNR and preserves downstream reasoning performance on ZebraLogic even under aggressive quantization.
  • The code is available at https://github.com/BeautMoonQ/ARHQ.

arXiv:2407.10853v5 Announce Type: replace-cross Abstract: Bias and fairness risks in Large Language Models (LLMs) vary substantially across deployment contexts, yet existing approaches lack systematic guidance for selecting appropriate evaluation metrics.

Key details

  • We present a decision framework that maps LLM use cases, characterized by a model and population of prompts, to relevant bias and fairness metrics based on task type, whether prompts contain protected attribute mentions, and stakeholder priorities.
  • Our framework addresses toxicity, stereotyping, counterfactual unfairness, and allocational harms, and introduces novel metrics based on stereotype classifiers and counterfactual adaptations of text similarity measures.
  • We release an open-source Python library, \texttt{langfair}, for practical adoption.
  • Extensive experiments on use cases across five LLMs and five prompt populations demonstrate that fairness risks cannot be reliably assessed from benchmark performance alone: results on one prompt dataset likely overstate or understate risks for another, und...

Next-step validation checks

  • Reproduce one claim with a public baseline and fixed evaluation settings.
  • Check robustness on out-of-distribution or long-context cases.
  • Track whether independent teams report matching results.
