Accelerating Deep Learning with Millions of Classes

no code implementations ECCV 2020 Zhuoning Yuan, Zhishuai Guo, Xiaotian Yu, Xiaoyu Wang, Tianbao Yang

In our experiment, we demonstrate that the proposed frame-work is able to train deep learning models with millions of classes and achieve above 10×speedup compared to existing approaches.

BiTA: Bi-Directional Tuning for Lossless Acceleration in Large Language Models

1 code implementation23 Jan 2024 Feng Lin, Hanling Yi, Hongbin Li, Yifan Yang, Xiaotian Yu, Guangming Lu, Rong Xiao

Large language models (LLMs) commonly employ autoregressive generation during inference, leading to high memory bandwidth demand and consequently extended latency.

How To Prevent the Continuous Damage of Noises To Model Training?

no code implementations CVPR 2023 Xiaotian Yu, Yang Jiang, Tianqi Shi, Zunlei Feng, Yuexuan Wang, Mingli Song, Li Sun

To address this problem, the proposed GSS alleviates the damage by switching the current gradient direction of each sample to a new direction selected from a gradient direction pool, which contains all-class gradient directions with different probabilities.

FaceMap: Towards Unsupervised Face Clustering via Map Equation

1 code implementation21 Mar 2022 Xiaotian Yu, Yifan Yang, Aibo Wang, Ling Xing, Hanling Yi, Guangming Lu, Xiaoyu Wang

Face clustering is an essential task in computer vision due to the explosion of related applications such as augmented reality or photo album management.

Contextual Bandits with Random Projection

no code implementations20 Mar 2019 Xiaotian Yu

Contextual bandits with linear payoffs, which are also known as linear bandits, provide a powerful alternative for solving practical problems of sequential decisions, e. g., online advertisements.

Multi-Armed Bandits

Almost Optimal Algorithms for Linear Stochastic Bandits with Heavy-Tailed Payoffs

no code implementations NeurIPS 2018 Han Shao, Xiaotian Yu, Irwin King, Michael R. Lyu

In this paper, under a weaker assumption on noises, we study the problem of \underline{lin}ear stochastic {\underline b}andits with h{\underline e}avy-{\underline t}ailed payoffs (LinBET), where the distributions have finite moments of order $1+\epsilon$, for some $\epsilon\in (0, 1]$.
