Concise and Precise Context Compression for Tool-Using Language Models

no code implementations2 Jul 2024 Yang Xu, Yunlong Feng, Honglin Mu, Yutai Hou, Yitong Li, Xinghao Wang, Wanjun Zhong, Zhongyang Li, Dandan Tu, Qingfu Zhu, Min Zhang, Wanxiang Che

However, when compressing tool documentation, existing methods suffer from the weaknesses of key information loss (specifically, tool/parameter name errors) and difficulty in adjusting the length of compressed sequences based on documentation lengths.

Improving Cross-Task Generalization with Step-by-Step Instructions

no code implementations8 May 2023 Yang Wu, Yanyan Zhao, Zhongyang Li, Bing Qin, Kai Xiong

Instruction tuning has been shown to be able to improve cross-task generalization of language models.

ReCo: Reliable Causal Chain Reasoning via Structural Causal Recurrent Neural Networks

1 code implementation16 Dec 2022 Kai Xiong, Xiao Ding, Zhongyang Li, Li Du, Bing Qin, Yi Zheng, Baoxing Huai

Causal chain reasoning (CCR) is an essential ability for many decision-making AI systems, which requires the model to build reliable causal chains by connecting causal pairs.

Exact Recovery of Community Detection in dependent Gaussian Mixture Models

no code implementations23 Sep 2022 Zhongyang Li, Sichen Yang

We study the community detection problem on a Gaussian mixture model, in which (1) vertices are divided into $k\geq 2$ distinct communities that are not necessarily equally-sized; (2) the Gaussian perturbations for different entries in the observation matrix are not necessarily independent or identically distributed.

On the coercivity condition in the learning of interacting particle systems

no code implementations20 Nov 2020 Zhongyang Li, Fei Lu

In the learning of systems of interacting particles or agents, coercivity condition ensures identifiability of the interaction functions, providing the foundation of learning by nonparametric regression.


Exact Recovery of Community Detection in k-Community Gaussian Mixture Model

no code implementations29 Aug 2020 Zhongyang Li

We study the community detection problem on a Gaussian mixture model, in which vertices are divided into $k\geq 2$ distinct communities.
