20 Minute Machine Learning Crash Course

At the brand new Climate Pledge Arena in Seattle, Amazon debuted their Just Walk Out cashierless technology to enable fans to get out of their store and back in their seats as quickly as possible. This impressive system by Amazon is a recent application of artificial intelligence, one of the most promising emerging technologies that will have (and already is having) a major impact on our world. If you are inspired by this or other applications of AI to utilize the technology in your own way, you have to start somewhere. This guide will help you get started with the technical side of AI, starting from defining what a neural network exactly is to finding ways to optimize training of a neural network. Images in this guide are from this free course on Udacity. Feel free to check it out! Neural networks are tools that can be used to solve classification problems. Given an image of a dish, classify it as a pancake or a waffle. Given a handwritten number, classify it as a digit from 0–9. In the above graph, we are trying to predict whether or not a student gets accepted into a particular university based on their grades and test scores.
