Frequency Pooling: Shift-Equivalent and Anti-Aliasing Down Sampling

no code implementations25 Sep 2019 Zhendong Zhang, Cheolkon Jung

Convolutional layer utilizes the shift-equivalent prior of images which makes it a great success for image processing.

GBDT-MO: Gradient Boosted Decision Trees for Multiple Outputs

3 code implementations10 Sep 2019 Zhendong Zhang, Cheolkon Jung

When there are multiple outputs, GBDT constructs multiple trees corresponding to the output variables.

Adversarial Defense by Suppressing High-frequency Components

1 code implementation19 Aug 2019 Zhendong Zhang, Cheolkon Jung, Xiaolong Liang

Recent works show that deep neural networks trained on image classification dataset bias towards textures.
