Spectral-graph Based Classifications: Linear Regression for Classification and Normalized Radial Basis Function Network

no code implementations19 May 2017 Zhenfang Hu, Gang Pan, Zhaohui Wu

The spectral graph theory provides us with a new insight into a fundamental aspect of classification: the tradeoff between fitting error and overfitting risk.

Two-Bit Networks for Deep Learning on Resource-Constrained Embedded Devices

no code implementations2 Jan 2017 Wenjia Meng, Zonghua Gu, Ming Zhang, Zhaohui Wu

With the rapid proliferation of Internet of Things and intelligent edge devices, there is an increasing need for implementing machine learning algorithms, including deep learning, on resource-constrained mobile embedded devices with limited memory and computation power.

Spectral Sparse Representation for Clustering: Evolved from PCA, K-means, Laplacian Eigenmap, and Ratio Cut

no code implementations25 Mar 2014 Zhenfang Hu, Gang Pan, Yueming Wang, Zhaohui Wu

The methods include PCA, K-means, Laplacian eigenmap (LE), ratio cut (Rcut), and a new sparse representation method developed by us, called spectral sparse representation (SSR).

Sparse Principal Component Analysis via Rotation and Truncation

no code implementations6 Mar 2014 Zhenfang Hu, Gang Pan, Yueming Wang, Zhaohui Wu

In contrast to most of existing work which deal with the problem by adding some sparsity penalties on various objectives of PCA, in this paper, we propose a new method SPCArt, whose motivation is to find a rotation matrix and a sparse basis such that the sparse basis approximates the basis of PCA after the rotation.
