Title: Why and Why Not Convolutional Neural Networks?

Abstract

The superior performance of Convolutional Neural Networks (CNNs) has been demonstrated in many applications such as image classification, detection and processing. Yet, the CNN solution has its weaknesses such as robustness against perturbation, scalability against the class number and portability among different datasets. Furthermore, CNN’s working principle remains mysterious. In this talk, I will present an alternative solution that is motivated by CNNs yet allows rigorous and transparent mathematical treatment based on a novel data-driven signal transform called the Saak (Subspace approximation with augmented kernels) transform. The Saak transform kernels are derived from the second-order statistics of inputs in a one-pass feedforward way. Neither data labels nor backpropagation is needed in kernel determination. The pros and cons of CNNs and multi-stage Saak transforms are compared. Speaker’s
