Rethinking Class Activation Maps for Segmentation: Revealing Semantic Information in Shallow Layers by Reducing Noise

no code implementations4 Aug 2023 Hang-Cheng Dong, Yuhao Jiang, Yingyan Huang, Jingxiao Liao, Bingguo Liu, Dong Ye, Guodong Liu

A major limitation to the performance of the class activation maps is the small spatial resolution of the feature maps in the last layer of the convolutional neural network.

One Neuron Saved Is One Neuron Earned: On Parametric Efficiency of Quadratic Networks

1 code implementation11 Mar 2023 Feng-Lei Fan, Hang-Cheng Dong, Zhongming Wu, Lecheng Ruan, Tieyong Zeng, Yiming Cui, Jing-Xiao Liao

In this paper, with theoretical and empirical studies, we show that quadratic networks enjoy parametric efficiency, thereby confirming that the superior performance of quadratic networks is due to the intrinsic expressive capability.

Attention-embedded Quadratic Network (Qttention) for Effective and Interpretable Bearing Fault Diagnosis

1 code implementation1 Jun 2022 Jing-Xiao Liao, Hang-Cheng Dong, Zhi-Qi Sun, Jinwei Sun, Shiping Zhang, Feng-Lei Fan

Bearing fault diagnosis is of great importance to decrease the damage risk of rotating machines and further improve economic profits.

Quadratic Neuron-empowered Heterogeneous Autoencoder for Unsupervised Anomaly Detection

1 code implementation2 Apr 2022 Jing-Xiao Liao, Bo-Jian Hou, Hang-Cheng Dong, Hao Zhang, Xiaoge Zhang, Jinwei Sun, Shiping Zhang, Feng-Lei Fan

Encouraged by this inspiring theoretical result on heterogeneous networks, we directly integrate conventional and quadratic neurons in an autoencoder to make a new type of heterogeneous autoencoders.
