EE-Tuning: An Economical yet Scalable Solution for Tuning Early-Exit Large Language Models

1 code implementation1 Feb 2024 Xuchen Pan, Yanxi Chen, Yaliang Li, Bolin Ding, Jingren Zhou

This work introduces EE-Tuning, a lightweight and economical solution to training/tuning early-exit large language models (LLMs).

EE-LLM: Large-Scale Training and Inference of Early-Exit Large Language Models with 3D Parallelism

1 code implementation8 Dec 2023 Yanxi Chen, Xuchen Pan, Yaliang Li, Bolin Ding, Jingren Zhou

We present EE-LLM, a framework for large-scale training and inference of early-exit large language models (LLMs).

Ranking from Pairwise Comparisons in General Graphs and Graphs with Locality

no code implementations13 Apr 2023 Yanxi Chen

This technical report studies the problem of ranking from pairwise comparisons in the classical Bradley-Terry-Luce (BTL) model, with a focus on score estimation.

A Surface-Based Federated Chow Test Model for Integrating APOE Status, Tau Deposition Measure, and Hippocampal Surface Morphometry

no code implementations31 Mar 2023 Jianfeng Wu, Yi Su, Yanxi Chen, Wenhui Zhu, Eric M. Reiman, Richard J. Caselli, Kewei Chen, Paul M. Thompson, Junwen Wang, Yalin Wang

Objective: To build a surface-based model to 1) detect differences between APOE subgroups in patterns of tau deposition and hippocampal atrophy, and 2) use the extracted surface-based features to predict cognitive decline.

Fast Computation of Optimal Transport via Entropy-Regularized Extragradient Methods

no code implementations30 Jan 2023 Gen Li, Yanxi Chen, Yuejie Chi, H. Vincent Poor, Yuxin Chen

Efficient computation of the optimal transport distance between two distributions serves as an algorithm subroutine that empowers various applications.

Learning Mixtures of Linear Dynamical Systems

no code implementations26 Jan 2022 Yanxi Chen, H. Vincent Poor

We study the problem of learning a mixture of multiple linear dynamical systems (LDSs) from unlabeled short sample trajectories, each generated by one of the LDS models.

Learning Mixtures of Low-Rank Models

no code implementations23 Sep 2020 Yanxi Chen, Cong Ma, H. Vincent Poor, Yuxin Chen

We study the problem of learning mixtures of low-rank models, i. e. reconstructing multiple low-rank matrices from unlabelled linear measurements of each.

Active Orthogonal Matching Pursuit for Sparse Subspace Clustering

no code implementations16 Aug 2017 Yanxi Chen, Gen Li, Yuantao Gu

In this letter, we propose a novel Active OMP-SSC, which improves clustering accuracy of OMP-SSC by adaptively updating data points and randomly dropping data points in the OMP process, while still enjoying the low computational complexity of greedy pursuit algorithms.
