Abstract:

This talk will focus on one particular type of deep learning networks known as the “multi-layer perception (MLP)”, “multi-layer feedforward networks” and “Convolutional neural networks (CNNs). It examines two topics in depth – network architectural evolution and theoretical foundation. For network architectural evolution, I will begin with the McClulloch and Pitts (M-P) neuron model and network in 1943, then the artificial neural network (ANN) in 80s and 90s, and finally the modern convolutional neural network (CNN) since late 90s. The differences between these three generations of networks will be clearly explained. Furthermore, there are three main types in modern CNNs: pyramidal CNNs, fully convolutional networks (FCN) and residual networks. Their specific functions are explained. For theoretical foundation, researchers have studied properties of CNNs from three viewpoints: the approximation theory viewpoint, the optimization theory viewpoint and, recently, the signal analysis viewpoint. I will present main results from each viewpoint. A good understanding of both topics provides valuable insights into the past, the present and the future of CNN research and applications.
