PPT-Training Neural Networks

Part 1 About me Or Nachmias No previous experience in neural networks Responsible to show the 2 nd most important lecture in the seminar References Stanford CS231 Convolution Neural Networks for Visual Recognition . 1. Recurrent Networks. Some problems require previous history/context in order to be able to give proper output (speech recognition, stock forecasting, target tracking, etc.. One way to do that is to just provide all the necessary context in one "snap-shot" and use standard learning. CAP5615 Intro. to Neural Networks. Xingquan (Hill) Zhu. Outline.
