Beyond Drift: Stabilizing Subjective LLM Evaluation with Information-Theoretic Rubrics

ICML 2026poster

Despite the growing use of large language models (LLMs) in subjective tasks such as role-playing, humor, emotional intelligence, and dialogue quality, their evaluation faces a pressing reproducibility crisis: even the same evaluator may contradict itself when re-judging the exact same sample. We att…

LoRA-drop: Efficient LoRA Parameter Pruning based on Output Evaluation

COLING 2025main

Low-Rank Adaptation (LoRA) is currently the most commonly used Parameter-efficient fine-tuning (PEFT) method. However, it still faces high computational and storage costs to models with billions of parameters. Most previous studies have tackled this issue by using pruning techniques. Nonetheless, th…

Ouroboros: Generating Longer Drafts Phrase by Phrase for Faster Speculative Decoding

EMNLP 2024main

Speculative decoding is a widely used method that accelerates the generation process of large language models (LLMs) with no compromise in model performance. It achieves this goal by using an existing smaller model for drafting and then employing the target LLM to verify the draft in a low-cost para…

Document-Level Relation Extraction with Sentences Importance Estimation and Focusing

NAACL 2022long

Document-level relation extraction (DocRE) aims to determine the relation between two entities from a document of multiple sentences. Recent studies typically represent the entire document by sequence- or graph-based models to predict the relations of all entity pairs. However, we find that such a m…

Jointly Learning Guidance Induction and Faithful Summary Generation via Conditional Variational Autoencoders

NAACL 2022findings

Abstractive summarization can generate high quality results with the development of the neural network. However, generating factual consistency summaries is a challenging task for abstractive summarization. Recent studies extract the additional information with off-the-shelf tools from the source do…
