AutoWebGLM: Bootstrap And Reinforce A Large Language Model-based Web Navigating Agent

1 code implementation4 Apr 2024 Hanyu Lai, Xiao Liu, Iat Long Iong, Shuntian Yao, Yuxuan Chen, Pengbo Shen, Hao Yu, Hanchen Zhang, Xiaohan Zhang, Yuxiao Dong, Jie Tang

Large language models (LLMs) have fueled many intelligent agent tasks, such as web navigation -- but most existing agents perform far from satisfying in real-world webpages due to three factors: (1) the versatility of actions on webpages, (2) HTML text exceeding model processing capacity, and (3) the complexity of decision-making due to the open-domain nature of web.

SLIC: Self-Supervised Learning with Iterative Clustering for Human Action Videos

1 code implementation CVPR 2022 Salar Hosseini Khorasgani, Yuxuan Chen, Florian Shkurti

One of the key reasons for this is that sampling pairs of similar video clips, a required step for many self-supervised contrastive learning methods, is currently done conservatively to avoid false positives.
