Multi-task Paired Masking with Alignment Modeling for Medical Vision-Language Pre-training

no code implementations13 May 2023 Ke Zhang, Yan Yang, Jun Yu, Hanliang Jiang, Jianping Fan, Qingming Huang, Weidong Han

To address this limitation, we propose a unified Med-VLP framework based on Multi-task Paired Masking with Alignment (MPMA) to integrate the cross-modal alignment task into the joint image-text reconstruction framework to achieve more comprehensive cross-modal interaction, while a Global and Local Alignment (GLA) module is designed to assist self-supervised paradigm in obtaining semantic representations with rich domain knowledge.

What Makes Pre-trained Language Models Better Zero-shot Learners?

1 code implementation30 Sep 2022 Jinghui Lu, Dongsheng Zhu, Weidong Han, Rui Zhao, Brian Mac Namee, Fei Tan

Current methods for prompt learning in zeroshot scenarios widely rely on a development set with sufficient human-annotated data to select the best-performing prompt template a posteriori.

Probabilistic Group Testing under Sum Observations: A Parallelizable 2-Approximation for Entropy Loss

no code implementations16 Jul 2014 Weidong Han, Purnima Rajan, Peter I. Frazier, Bruno M. Jedynak

We consider the problem of group testing with sum observations and noiseless answers, in which we aim to locate multiple objects by querying the number of objects in each of a sequence of chosen sets.
