How do Neural Networks really work? - Analytics Vidhya

Neural networks form the core of deep learning, a subset of machine learning that I introduced in my previous article. People exposed to artificial intelligence generally have a good high-level idea of how a neural network works -- data is passed from one layer of the neural network to the next, and this data is propagated from the topmost layer to the bottom layer until, somehow, the algorithm outputs the prediction on whether an image is that of a chihuahua or a muffin. Seems like magic, isn't it? Surprisingly, neural networks for a computer vision model can be understood using high school math. It just requires the correct explanation in the simplest manner for everyone to understand how neural networks work under the hood.
