Large Language Models in Medical Term Classification and Unexpected Misalignment Between Response and Reasoning

no code implementations19 Dec 2023 Xiaodan Zhang, Sandeep Vemulapalli, Nabasmita Talukdar, Sumyeong Ahn, Jiankun Wang, Han Meng, Sardar Mehtab Bin Murtaza, Aakash Ajay Dave, Dmitry Leshchiner, Dimitri F. Joseph, Martin Witteveen-Lane, Dave Chesla, Jiayu Zhou, Bin Chen

This study assesses the ability of state-of-the-art large language models (LLMs) including GPT-3. 5, GPT-4, Falcon, and LLaMA 2 to identify patients with mild cognitive impairment (MCI) from discharge summaries and examines instances where the models' responses were misaligned with their reasoning.

General Phrase Debiaser: Debiasing Masked Language Models at a Multi-Token Level

1 code implementation23 Nov 2023 Bingkang Shi, Xiaodan Zhang, Dehan Kong, Yulei Wu, Zongzhen Liu, Honglei Lyu, Longtao Huang

The social biases and unwelcome stereotypes revealed by pretrained language models are becoming obstacles to their application.

Generic Attention-model Explainability by Weighted Relevance Accumulation

no code implementations20 Aug 2023 Yiming Huang, Aozhe Jia, Xiaodan Zhang, Jiawei Zhang

In this paper, we propose a weighted relevancy strategy, which takes the importance of token values into consideration, to reduce distortion when equally accumulating relevance.

A Gated Peripheral-Foveal Convolutional Neural Network for Unified Image Aesthetic Prediction

no code implementations19 Dec 2018 Xiaodan Zhang, Xinbo Gao, Wen Lu, Lihuo He

The former aims to mimic the functions of peripheral vision to encode the holistic information and provide the attended regions.

Delving Into Salient Object Subitizing and Detection

no code implementations ICCV 2017 Shengfeng He, Jianbo Jiao, Xiaodan Zhang, Guoqiang Han, Rynson W. H. Lau

Experiments show that the proposed multi-task network outperforms existing multi-task architectures, and the auxiliary subitizing network provides strong guidance to salient object detection by reducing false positives and producing coherent saliency maps.
