AutoAgents: A Framework for Automatic Agent Generation

1 code implementation29 Sep 2023 Guangyao Chen, Siwei Dong, Yu Shu, Ge Zhang, Jaward Sesay, Börje F. Karlsson, Jie Fu, Yemin Shi

Therefore, we introduce AutoAgents, an innovative framework that adaptively generates and coordinates multiple specialized agents to build an AI team according to different tasks.

Learning Sparse Neural Networks with Identity Layers

no code implementations14 Jul 2023 Mingjian Ni, Guangyao Chen, Xiawu Zheng, Peixi Peng, Li Yuan, Yonghong Tian

Applying such theory, we propose a plug-and-play CKA-based Sparsity Regularization for sparse network training, dubbed CKA-SR, which utilizes CKA to reduce feature similarity between layers and increase network sparsity.

Picking Up Quantization Steps for Compressed Image Classification

1 code implementation21 Apr 2023 Li Ma, Peixi Peng, Guangyao Chen, Yifan Zhao, Siwei Dong, Yonghong Tian

The sensitivity of deep neural networks to compressed images hinders their usage in many real applications, which means classification networks may fail just after taking a screenshot and saving it as a compressed file.

Large-scale Multi-Modal Pre-trained Models: A Comprehensive Survey

1 code implementation20 Feb 2023 Xiao Wang, Guangyao Chen, Guangwu Qian, Pengcheng Gao, Xiao-Yong Wei, YaoWei Wang, Yonghong Tian, Wen Gao

We also give visualization and analysis of the model parameters and results on representative downstream tasks.

Training Full Spike Neural Networks via Auxiliary Accumulation Pathway

2 code implementations27 Jan 2023 Guangyao Chen, Peixi Peng, Guoqi Li, Yonghong Tian

The accumulation in AAP could compensate for the information loss during the forward and backward of full spike propagation, and facilitate the training of the FSNN.

OpenOOD: Benchmarking Generalized Out-of-Distribution Detection

3 code implementations13 Oct 2022 Jingkang Yang, Pengyun Wang, Dejian Zou, Zitang Zhou, Kunyuan Ding, Wenxuan Peng, Haoqi Wang, Guangyao Chen, Bo Li, Yiyou Sun, Xuefeng Du, Kaiyang Zhou, Wayne Zhang, Dan Hendrycks, Yixuan Li, Ziwei Liu

Out-of-distribution (OOD) detection is vital to safety-critical machine learning applications and has thus been extensively studied, with a plethora of methods developed in the literature.

Amplitude-Phase Recombination: Rethinking Robustness of Convolutional Neural Networks in Frequency Domain

1 code implementation ICCV 2021 Guangyao Chen, Peixi Peng, Li Ma, Jia Li, Lin Du, Yonghong Tian

This observation leads to more explanations of the CNN's generalization behaviors in both robustness to common perturbations and out-of-distribution detection, and motivates a new perspective on data augmentation designed by re-combing the phase spectrum of the current image and the amplitude spectrum of the distracter image.
