Instance-level Randomization: Toward More Stable LLM Evaluations

EMNLP 2025

Evaluations of large language models (LLMs) suffer from instability, where small changes of random factors such as few-shot examples can lead to drastic fluctuations of scores and even model rankings. Moreover, different LLMs can have different preferences for a certain setting of random factors. As

SciEval: A Multi-Level Large Language Model Evaluation Benchmark for Scientific Research

AAAI 2024technical

Recently, there has been growing interest in using Large Language Models (LLMs) for scientific research. Numerous benchmarks have been proposed to evaluate the ability of LLMs for scientific research. However, current benchmarks are mostly based on pre-collected objective questions. This design suff…

Sparsity-Accelerated Training for Large Language Models

ACL 2024findings

Large language models (LLMs) have demonstrated proficiency across various natural language processing (NLP) tasks but often require additional training, such as continual pre-training and supervised fine-tuning. However, the costs associated with this, primarily due to their large parameter count, r…

META-GUI: Towards Multi-modal Conversational Agents on Mobile GUI

EMNLP 2022main

Task-oriented dialogue (TOD) systems have been widely used by mobile phone intelligent assistants to accomplish tasks such as calendar scheduling or hotel reservation. Current TOD systems usually focus on multi-turn text/speech interaction, then they would call back-end APIs designed for TODs to per…
