DNR Bench: Benchmarking Over-Reasoning in Reasoning LLMs

AAAI 2026technical

Test-time scaling has significantly improved large language model (LLM) performance, enabling deeper reasoning to solve complex problems. However, this increased reasoning capability also leads to excessive token generation and unnecessary problem-solving attempts. We introduce "Don

Auto-Cypher: Improving LLMs on Cypher generation via LLM-supervised generation-verification framework

NAACL 2025short

Graph databases like Neo4j are gaining popularity for handling complex, interconnected data, over traditional relational databases in modeling and querying relationships. While translating natural language into SQL queries is well-researched, generating Cypher queries for Neo4j remains relatively un…

Do LLMs Know When to NOT Answer? Investigating Abstention Abilities of Large Language Models

COLING 2025main

Abstention Ability (AA) is a critical aspect of Large Language Model (LLM) reliability, referring to an LLM’s capability to withhold responses when uncertain or lacking a definitive answer, without compromising performance. Although previous studies have attempted to improve AA, they lack a standard…

Prompting with Phonemes: Enhancing LLMs’ Multilinguality for Non-Latin Script Languages

NAACL 2025long

Multilingual LLMs have achieved remarkable benchmark performance, but we find they continue to underperform on non-Latin script languages across contemporary LLM families. This discrepancy arises from the fact that LLMs are pretrained with orthographic scripts, which are dominated by Latin character…

PUMA: Performance Unchanged Model Augmentation for Training Data Removal

AAAI 2022technical

Preserving the performance of a trained model while removing unique characteristics of marked training data points is challenging. Recent research usually suggests retraining a model from scratch with remaining training data or refining the model by reverting the model optimization on the marked dat…
