This projects aims at creating a simulator for the NARX (Nonlinear AutoRegressive with eXogenous inputs ) architecture with neural networks. TL;DR: By using pruning a VGG-16 based Dogs-vs-Cats classifier is made x3 faster and x4 smaller. This is a list of hacks gathered primarily from prior experiences as well as online sources (most notably Stanford's CS231n course notes) on how to troubleshoot the performance of a convolutional neural network. It takes an input image and transforms it through a series of functions into class probabilities at the end. In this article, I will talk about how I use pipelines and mind maps for training convolutional neural networks, using the German Traffic Sign image classification project as an example. In this project we created a convolutional neural network and used it to classify the CIFAR-10 dataset.
