Fast-Convergent Fully Connected Deep Learning Model Using Constrained Nodes Input

摘要

Recently, deep learning models exhibit promising performance in various applications. However, most of them converge slowly due to gradient vanishing. To address this problem, we propose a fast convergent fully connected deep learning network in this study. Through constraining the input values of nodes on the fully connected layers, the proposed method is able to well mitigate the gradient vanishing problems in training phase, and thus greatly reduces the training iterations required to reach convergence. Nevertheless, the drop of generalization performance is negligible. Experimental results validate the effectiveness of the proposed method.
