Squeezed Very Deep Convolutional Neural Networks for Text Classification

Abstract--Most of the research in convolutional neural networks hasfocused on increasing network depth to improve accuracy, resulting in a massive number of parameters which restricts the trained network to platforms with memory and processing constraints. We propose to modify the structure of the Very Deep Convolutional Neural Networks (VDCNN) model to fit mobile platforms constraints and keep performance. In this paper, we evaluate the impact of Temporal Depthwise Separable Convolutions and Global Average Pooling in the network parameters, storagesize, and latency. The squeezed model (SVDCNN) is between 10x and 20x smaller, depending on the network depth, maintaining a maximum size of 6MB. Regarding accuracy, the network experiences a loss between 0.4% and 1.3% and obtains lower latencies compared to the baseline model. I. INTRODUCTION The general trend in deep learning approaches has been developing models with increasing layers. Deep models can also learn hierarchical feature representations from images [1].
