Reverse Chain: A Generic-Rule for LLMs to Master Multi-API Planning

1 code implementation6 Oct 2023 Yinger Zhang, Hui Cai, Xeirui Song, Yicheng Chen, Rui Sun, Jing Zheng

While enabling large language models to implement function calling (known as APIs) can greatly enhance the performance of Large Language Models (LLMs), function calling is still a challenging task due to the complicated relations between different APIs, especially in a context-learning setting without fine-tuning.

Learning-Initialized Trajectory Planning in Unknown Environments

no code implementations19 Sep 2023 Yicheng Chen, Jinjie Li, Wenyuan Qin, Yongzhao Hua, Xiwang Dong, Qingdong Li

Autonomous flight in unknown environments requires precise planning for both the spatial and temporal profiles of trajectories, which generally involves nonconvex optimization, leading to high time costs and susceptibility to local optima.

Communication-Efficient {Federated} Learning Using Censored Heavy Ball Descent

no code implementations24 Sep 2022 Yicheng Chen, Rick S. Blum, Brian M. Sadler

The significant practical advantages of the HB method for learning problems are well known, but the question of reducing communications has not been addressed.

Communication Efficient Federated Learning via Ordered ADMM in a Fully Decentralized Setting

no code implementations5 Feb 2022 Yicheng Chen, Rick S. Blum, Brian M. Sadler

Compared to the classical ADMM, a key feature of OADMM is that transmissions are ordered among workers at each iteration such that a worker with the most informative data broadcasts its local variable to neighbors first, and neighbors who have not transmitted yet can update their local variables based on that received transmission.

Distributed Optimization Federated Learning

Distributed Learning With Sparsified Gradient Differences

no code implementations5 Feb 2022 Yicheng Chen, Rick S. Blum, Martin Takac, Brian M. Sadler

A very large number of communications are typically required to solve distributed learning tasks, and this critically limits scalability and convergence speed in wireless communications applications.
