Do Before You Judge: Self-Reference as a Pathway to Better LLM Evaluation

EMNLP 2025

LLM-as-Judge frameworks are increasingly popular for AI evaluation, yet research findings on the relationship between models’ generation and judgment abilities remain inconsistent. We investigate this relationship through systematic dataset- and instance-level analyses across 11 models and 21 divers

Efficient Beam Search for Large Language Models Using Trie-Based Decoding

EMNLP 2025

This work presents a novel trie (prefix-tree)-based parallel decoding method that addresses the memory inefficiency of batch-based beam search. By sharing a single KV cache across beams with common prefixes, our approach dramatically reduces memory usage and enables efficient decoding. We evaluated

Self-Augmented Preference Alignment for Sycophancy Reduction in LLMs

EMNLP 2025

Sycophancy causes models to produce answers that cater to user expectations rather than providing truthful responses. Sycophantic behavior in models can erode user trust by creating a perception of dishonesty or bias. This lack of authenticity may lead users to question the reliability and objectivi

Using Contextually Aligned Online Reviews to Measure LLMs’ Performance Disparities Across Language Varieties

NAACL 2025short

A language can have different varieties. These varieties can affect the performance of natural language processing (NLP) models, including large language models (LLMs), which are often trained on data from widely spoken varieties. This paper introduces a novel and cost-effective approach to benchmar…

Induct-Learn: Short Phrase Prompting with Instruction Induction

EMNLP 2024main

Large Language Models (LLMs) have demonstrated capability in “instruction induction,” generating instructions from demonstrations (input-output pairs). However, existing methods often rely on large datasets or numerous examples, which is impractical and costly in real-world scenarios. In this work,…

Unveiling Selection Biases: Exploring Order and Token Sensitivity in Large Language Models

ACL 2024findings

In this paper, we investigate the phenomena of “selection biases” in Large Language Models (LLMs), focusing on problems where models are tasked with choosing the optimal option from an ordered sequence. We delve into biases related to option order and token usage, which significantly impact LLMs’ de…

ZARA: Improving Few-Shot Self-Rationalization for Small Language Models

EMNLP 2023long findings

Language models (LMs) that jointly generate end-task answers as well as free-text rationales are known as self-rationalization models. Recent works demonstrate great performance gain for self-rationalization by few-shot prompting LMs with rationale-augmented exemplars. However, the ability to benefi…

SEEN: Structured Event Enhancement Network for Explainable Need Detection of Information Recall Assistance

EMNLP 2022main

When recalling life experiences, people often forget or confuse life events, which necessitates information recall services. Previous work on information recall focuses on providing such assistance reactively, i.e., by retrieving the life event of a given query. Proactively detecting the need for in…
