On Entity Identification in Language Models

ACL 2025finding

We analyze the extent to which internal representations of language models (LMs) identify and distinguish mentions of named entities, focusing on the many-to-many correspondence between entities and their mentions.We first formulate two problems of entity mentions — ambiguity and variability — and p…

STEP: Staged Parameter-Efficient Pre-training for Large Language Models

NAACL 2025short

Pre-training large language models (LLMs) faces significant memory challenges due to the large size of model weights. We introduce STaged parameter-Efficient Pre-training (STEP), which integrates parameter-efficient tuning techniques with model growth. We conduct experiments on pre-training LLMs of…

Investigating the Effectiveness of Multiple Expert Models Collaboration

EMNLP 2023short findings

This paper aims to investigate the effectiveness of several machine translation (MT) models and aggregation methods in a multi-domain setting under fair conditions and explore a direction for tackling multi-domain MT. We mainly compare the performance of the single model approach by jointly training…

Hoverability Analysis and Development of a Quadrotor Only with Clockwise Rotors

IROS 2022poster

This paper presents novel quadrotor structures composed of only clockwise rotors. A multirotor unmanned aerial vehicle (UAV) generally has both clockwise and counterclockwise rotors to counteract the torques from the rotors. While the proposed structures have only clockwise rotors, those rotors are…

Lower Perplexity is Not Always Human-Like

ACL 2021long

In computational psycholinguistics, various language models have been evaluated against human reading behavior (e.g., eye movement) to build human-like computational models. However, most previous efforts have focused almost exclusively on English, despite the recent trend towards linguistic univers…
