DRIFT: Learning from Abundant User Dissatisfaction in Real-World Preference Learning

ICLR 2026poster

Real-world large language model deployments (e.g., conversational AI systems, code generation assistants) naturally generate abundant implicit user dissatisfaction (DSAT) signals, as users iterate toward better answers through refinements, corrections, and expressed preferences, while explicit satis…

CodeTaxo: Enhancing Taxonomy Expansion with Limited Examples via Code Language Prompts

ACL 2025finding

Taxonomies provide structural representations of knowledge and are crucial in various applications. The task of taxonomy expansion involves integrating emerging entities into existing taxonomies by identifying appropriate parent entities for these new query entities. Previous methods rely on self-su…

Enhancing Mathematical Reasoning in LLMs by Stepwise Correction

ACL 2025long

Best-of-N decoding methods instruct large language models (LLMs) to generate multiple solutions, score each using a scoring function, and select the highest scored as the final answer to mathematical reasoning problems. However, this repeated independent process often leads to the same mistakes, mak…

Pre-trained Models Perform the Best When Token Distributions Follow Zipf’s Law

EMNLP 2025

Tokenization is a fundamental step in natural language processing (NLP) and other sequence modeling domains, where the choice of vocabulary size significantly impacts model performance. Despite its importance, selecting an optimal vocabulary size remains underexplored, typically relying on heuristic

Protecting Privacy in Multimodal Large Language Models with MLLMU-Bench

NAACL 2025long

Generative models such as Large Language Models (LLM) and Multimodal Large Language models (MLLMs) trained on massive web corpora can memorize and disclose individuals’ confidential and private data, raising legal and ethical concerns. While many previous works have addressed this issue in LLM via m…

Democratizing Large Language Models via Personalized Parameter-Efficient Fine-tuning

EMNLP 2024main

Personalization in large language models (LLMs) is increasingly important, aiming to align the LLMs’ interactions, content, and recommendations with individual user preferences. Recent advances have highlighted effective prompt design by enriching user queries with non-parametric knowledge through b…

Large Language Models Can Self-Correct with Key Condition Verification

EMNLP 2024main

Intrinsic self-correct was a method that instructed large language models (LLMs) to verify and correct their responses without external feedback. Unfortunately, the study concluded that the LLMs could not self-correct reasoning yet. We find that a simple yet effective prompting method enhances LLM p…

MinT: Boosting Generalization in Mathematical Reasoning via Multi-view Fine-tuning

COLING 2024main

Reasoning in mathematical domains remains a significant challenge for relatively small language models (LMs). Many current methods focus on specializing LMs in mathematical reasoning and rely heavily on distilling knowledge from powerful yet inefficient large LMs (LLMs). In this work, we explore a n…

Auto-Instruct: Automatic Instruction Generation and Ranking for Black-Box Language Models

EMNLP 2023long findings

Large language models (LLMs) can perform a wide range of tasks by following natural language instructions, without the necessity of task-specific fine-tuning. Unfortunately, the performance of LLMs is greatly influenced by the quality of these instructions, and manually writing effective instruction…

Enhancing Factual Consistency of Abstractive Summarization

NAACL 2021long

Automatic abstractive summaries are found to often distort or fabricate facts in the article. This inconsistency between summary and original text has seriously impacted its applicability. We propose a fact-aware summarization model FASum to extract and integrate factual relations into the summary g…

Technical Question Answering across Tasks and Domains

NAACL 2021industry

Building automatic technical support system is an important yet challenge task. Conceptually, to answer a user question on a technical forum, a human expert has to first retrieve relevant documents, and then read them carefully to identify the answer snippet. Despite huge success the researchers hav…
