“Convolutional Neural Network Optimization: The Key to AI/Computer Vision Advancement”

Abstract:

Convolutional neural networks (CNNs) have emerged to provide powerful discriminative capability, especially in the world of image recognition and object detection. However, their massive computation requirements, storage and memory accesses make them hard to be deployed on mobile or embedded systems. In this talk, several optimization schemes for Convolutional neural networks (CNNs) will be first reviewed. Some hardware architectures of computing platforms for executing CNN are also reviewed. We will then discuss the usefulness of the optimization methods and especially emphasize the quantization technique since it can benefit many kinds of computing architectures. A dedicated hardware architecture design for face detection will also be shown as an example.
