Unbiased Contrastive Divergence Algorithm for Training Energy-Based Latent Variable Models

1 code implementation ICLR 2020 Yixuan Qiu, Lingsong Zhang, Xiao Wang

The contrastive divergence algorithm is a popular approach to training energy-based latent variable models, which has been widely used in many machine learning models such as the restricted Boltzmann machines and deep belief nets.

Distance-weighted Support Vector Machine

no code implementations11 Oct 2013 Xingye Qiao, Lingsong Zhang

The proposed Distance-weighted Support Vector Machine method can be viewed as a hybrid of SVM and DWD that finds the classification direction by minimizing mainly the DWD loss, and determines the intercept term in the SVM manner.

Nested Nonnegative Cone Analysis

no code implementations20 Aug 2013 Lingsong Zhang, J. S. Marron, Shu Lu

The application of traditional PCA/SVD method to nonnegative data often cause the approximation matrix leave the nonnegative cone, which leads to non-interpretable and sometimes nonsensical results.
