I started my master's degree at the Technion with no knowledge regarding neural networks(NN) and a lot of motivation to create a better search engine than Google. After 8 months of hard yet interesting work, I came to the conclusion that I will not be able to achieve my goal using the hardware that was at my disposal. In this lecture, I will talk about how to start working with NN from scratch and all lessons I learned in the way of applying NN in a domain which requires large amounts of data and NN is not the conventional approach.
