Part III: Convolutional Neural Networks Presented by Ryan Butler & Yuji Akimoto. Lenet-5 (Lecun-98), Convolutional Neural Network for digits recognition. • Consists of convolution and pooling layers: • Convolution: Moves small filters over input images; the values of the filters are adjusted by the network as it trains. In the proposal sub-network, detection is performed at multiple output layers, so that receptive fields match objects of different scales. Thanks to deep learning, computer vision is working far better than just two years ago, and this is enabling numerous exciting applications ranging from safe autonomous driving, to accurate face recognition, to automatic reading of radiology images. Each of these layers has different parameters that can be optimized and performs a different task on the input data. Finally, the implementation of the CNNs is demonstrated by implementing the paper 'Age ang Gender Classification Using Convolutional Neural Networks' by Hassner (2015). The Basics A convolutional neural network (CNN) is constructed by stacking multiple computation layers as a directed acyclic graph. Neural Networks and Deep Learning. Network visualization: Visualization of filters in a C-NN is the most direct way of exploring the pattern hidden inside a neural unit. A convolution is essentially sliding a filter over the input.
