Event Schema Induction with Double Graph Autoencoders

no code implementations NAACL 2022 Xiaomeng Jin, Manling Li, Heng Ji

To induce event schemas from historical events, previous work uses an event-by-event scheme, ignoring the global structure of the entire schema graph.

Contrastive Visual Data Augmentation

no code implementations24 Feb 2025 Yu Zhou, Bingxuan Li, Mohan Tang, Xiaomeng Jin, Te-Lin Wu, Kuan-Hao Huang, Heng Ji, Kai-Wei Chang, Nanyun Peng

Large multimodal models (LMMs) often struggle to recognize novel concepts, as they rely on pre-trained knowledge and have limited ability to capture subtle visual details.

LUME: LLM Unlearning with Multitask Evaluations

no code implementations20 Feb 2025 Anil Ramakrishna, Yixin Wan, Xiaomeng Jin, Kai-Wei Chang, Zhiqi Bu, Bhanukiran Vinzamuri, Volkan Cevher, Mingyi Hong, Rahul Gupta

Unlearning aims to remove copyrighted, sensitive, or private content from large language models (LLMs) without a full retraining.

ARMADA: Attribute-Based Multimodal Data Augmentation

no code implementations19 Aug 2024 Xiaomeng Jin, Jeonghwan Kim, Yu Zhou, Kuan-Hao Huang, Te-Lin Wu, Nanyun Peng, Heng Ji

To address these issues, we propose Attribute-based Multimodal Data Augmentation (ARMADA), a novel multimodal data augmentation method via knowledge-guided manipulation of visual attributes of the mentioned entities.

On the Sensitivity of Adversarial Robustness to Input Data Distributions

no code implementations ICLR 2019 Gavin Weiguang Ding, Kry Yik Chau Lui, Xiaomeng Jin, Luyu Wang, Ruitong Huang

Even a semantics-preserving transformations on the input data distribution can cause a significantly different robustness for the adversarial trained model that is both trained and evaluated on the new distribution.
