Unconstrained optimization using the directional proximal point method

Ming-Yu Chung, Jinn Ho, Wen-Liang Hwang

This paper presents a directional proximal point method (DPPM) to derive the minimum of any C1-smooth function f. The proposed method requires a function persistent a local convex…

Learning DNN networks using un-rectifying ReLU with compressed sensing application

Wen-Liang Hwang, Shih-Shuo Tung

The un-rectifying technique expresses a non-linear point-wise activation function as a data-dependent variable, which means that the activation variable along with its input and ou…

Deep Representation with ReLU Neural Networks

Andreas Heinecke, Wen-Liang Hwang

We consider deep feedforward neural networks with rectified linear units from a signal processing perspective. In this view, such representations mark the transition from using a s…

Sparse Representation of a Blur Kernel for Blind Image Restoration

Chia-Chen Lee, Wen-Liang Hwang

Blind image restoration is a non-convex problem which involves restoration of images from an unknown blur kernel. The factors affecting the performance of this restoration are how…
