Negative Sample Matters: A Renaissance of Metric Learning for Temporal Grounding

2 code implementations10 Sep 2021 Zhenzhi Wang, LiMin Wang, Tao Wu, TianHao Li, Gangshan Wu

Instead, from a perspective on temporal grounding as a metric-learning problem, we present a Mutual Matching Network (MMN), to directly model the similarity between language queries and video moments in a joint embedding space.

Steady state behavior of the free recall dynamics of working memory

no code implementations22 Sep 2022 TianHao Li, Zhixin Liu, Lizheng Liu, Xiaoming Hu

Finally, we give a sufficient condition under which this model has a globally asymptotically stable equilibrium with synchronized minicolumn states in each hypercolumn, which implies that in this case recalling is impossible.

CancerGPT: Few-shot Drug Pair Synergy Prediction using Large Pre-trained Language Models

no code implementations18 Apr 2023 TianHao Li, Sandesh Shetty, Advaith Kamath, Ajay Jaiswal, Xianqian Jiang, Ying Ding, Yejin Kim

Large pre-trained language models (LLMs) have been shown to have significant potential in few-shot learning across various fields, even with minimal training data.

Controllability of networked multiagent systems based on linearized Turing's model

no code implementations26 Oct 2023 TianHao Li, Ruichang Zhang, Zhixin Liu, Zhuo Zou, Xiaoming Hu

Under mild conditions on the parameters of the linearized Turing's model, we prove the equivalence between controllability of the linearized Turing's model and controllability of a Laplace dynamic system with agents of first order dynamics.
