WCP: Worst-Case Perturbations for Semi-Supervised Deep Learning

1 code implementation CVPR 2020 Liheng Zhang, Guo-Jun Qi

The WCP can be minimized on both labeled and unlabeled data so that networks can be trained in a semi-supervised fashion.

Learning Generalized Transformation Equivariant Representations via Autoencoding Transformations

no code implementations19 Jun 2019 Guo-Jun Qi, Liheng Zhang, Xiao Wang

Transformation Equivariant Representations (TERs) aim to capture the intrinsic visual structures that equivary to various transformations by expanding the notion of {\em translation} equivariance underlying the success of Convolutional Neural Networks (CNNs).

AVT: Unsupervised Learning of Transformation Equivariant Representations by Autoencoding Variational Transformations

1 code implementation ICCV 2019 Guo-Jun Qi, Liheng Zhang, Chang Wen Chen, Qi Tian

This ensures the resultant TERs of individual images contain the {\em intrinsic} information about their visual structures that would equivary {\em extricably} under various transformations in a generalized {\em nonlinear} case.

AET vs. AED: Unsupervised Representation Learning by Auto-Encoding Transformations rather than Data

1 code implementation CVPR 2019 Liheng Zhang, Guo-Jun Qi, Liqiang Wang, Jiebo Luo

The success of deep neural networks often relies on a large amount of labeled examples, which can be difficult to obtain in many real scenarios.

CapProNet: Deep Feature Learning via Orthogonal Projections onto Capsule Subspaces

no code implementations NeurIPS 2018 Liheng Zhang, Marzieh Edraki, Guo-Jun Qi

In this paper, we formalize the idea behind capsule nets of using a capsule vector rather than a neuron activation to predict the label of samples.

Global versus Localized Generative Adversarial Nets

2 code implementations CVPR 2018 Guo-Jun Qi, Liheng Zhang, Hao Hu, Marzieh Edraki, Jingdong Wang, Xian-Sheng Hua

In this paper, we present a novel localized Generative Adversarial Net (GAN) to learn on the manifold of real data.

Stock Price Prediction via Discovering Multi-Frequency Trading Patterns

1 code implementation13 Aug 2017 Liheng Zhang, Charu Aggarwal, Guo-Jun Qi

Then the future stock prices are predicted as a nonlinear mapping of the combination of these components in an Inverse Fourier Transform (IFT) fashion.
