MetaFormer is Actually What You Need for Vision

2 code implementations22 Nov 2021 Weihao Yu, Mi Luo, Pan Zhou, Chenyang Si, Yichen Zhou, Xinchao Wang, Jiashi Feng, Shuicheng Yan

Based on this observation, we hypothesize that the general architecture of the transformers, instead of the specific token mixer module, is more essential to the model's performance.

Malicious Mode Attack on EV Coordinated Charging Load and MIADRC Defense Strategy

no code implementations26 Oct 2021 Yichen Zhou, Weidong Liu, Jing Ma, Xinghao Zhen, Yonggang Li

Further, to mitigate the impact of MMA, a defense strategy based on multi-index information active disturbance rejection control is proposed to improve the stability and anti-disturbance ability of the power system, which considers the impact factors of both mode damping and disturbance compensation.

Distilling Double Descent

no code implementations13 Feb 2021 Andrew Cotter, Aditya Krishna Menon, Harikrishna Narasimhan, Ankit Singh Rawat, Sashank J. Reddi, Yichen Zhou

Distillation is the technique of training a "student" model based on examples that are labeled by a separate "teacher" model, which itself is trained on a labeled dataset.

Approximate Heavily-Constrained Learning with Lagrange Multiplier Models

no code implementations NeurIPS 2020 Harikrishna Narasimhan, Andrew Cotter, Yichen Zhou, Serena Wang, Wenshuo Guo

In machine learning applications such as ranking fairness or fairness over intersectional groups, one often encounters optimization problems with an extremely large number of constraints.

A Simple Baseline for Pose Tracking in Videos of Crowded Scenes

no code implementations16 Oct 2020 Li Yuan, Shuning Chang, Ziyuan Huang, Yichen Zhou, Yunpeng Chen, Xuecheng Nie, Francis E. H. Tay, Jiashi Feng, Shuicheng Yan

This paper presents our solution to ACM MM challenge: Large-scale Human-centric Video Analysis in Complex Events\cite{lin2020human}; specifically, here we focus on Track3: Crowd Pose Tracking in Complex Events.

Toward Accurate Person-level Action Recognition in Videos of Crowded Scenes

no code implementations16 Oct 2020 Li Yuan, Yichen Zhou, Shuning Chang, Ziyuan Huang, Yunpeng Chen, Xuecheng Nie, Tao Wang, Jiashi Feng, Shuicheng Yan

Prior works always fail to deal with this problem in two aspects: (1) lacking utilizing information of the scenes; (2) lacking training data in the crowd and complex scenes.

Tree Boosted Varying Coefficient Models

1 code implementation1 Apr 2019 Yichen Zhou, Giles Hooker

This paper investigates the integration of gradient boosted decision trees and varying coefficient models.

Methodology

A Deep-Learning-Based Fashion Attributes Detection Model

1 code implementation24 Oct 2018 Menglin Jia, Yichen Zhou, Mengyun Shi, Bharath Hariharan

Such information analyzing process is called abstracting, which recognize similarities or differences across all the garments and collections.

Approximation Trees: Statistical Stability in Model Distillation

no code implementations22 Aug 2018 Yichen Zhou, Zhengze Zhou, Giles Hooker

Here, we consider the use of regression trees as a student model, in which nodes of the tree can be used as `explanations' for particular predictions, and the whole structure of the tree can be used as a global representation of the resulting function.
