CELLO: Causal Evaluation of Large Vision-Language Models

1 code implementation27 Jun 2024 Meiqi Chen, Bo Peng, Yan Zhang, Chaochao Lu

Previous work typically focuses on commonsense causality between events and/or actions, which is insufficient for applications like embodied agents and lacks the explicitly defined causal graphs required for formal causal reasoning.

Quantifying and Mitigating Unimodal Biases in Multimodal Large Language Models: A Causal Perspective

1 code implementation27 Mar 2024 Meiqi Chen, Yixin Cao, Yan Zhang, Chaochao Lu

Within this framework, we conduct an in-depth causal analysis to assess the causal effect of these biases on MLLM predictions.

ERGO: Event Relational Graph Transformer for Document-level Event Causality Identification

no code implementations COLING 2022 Meiqi Chen, Yixin Cao, Kunquan Deng, Mukai Li, Kun Wang, Jing Shao, Yan Zhang

In this paper, we propose a novel Event Relational Graph TransfOrmer (ERGO) framework for DECI, which improves existing state-of-the-art (SOTA) methods upon two aspects.
