Build an AI from Scratch | Neural Network Java
Let's build a #NeuralNetwork from scratch. After seeing many demos of how an AI solves a problem or plays a game, I realized there are not enough videos of how to actually write such an AI, so I set myself to write a Neural Network and a Genetic Algorithm to teach itself to play the Snake Game. This is the first episode in this series.

👨💻 About me
🖥 I am a software developer with more than 20 years of experience in the tech industry. I love to teach, debug problems and optimize my code for perfection.
📽 In my channel, you find videos describing how to solve coding problems, develop games, prep for job interviews and overall talk tech. I chose the name AppliedCoding, because I will teach you exactly that - applied coding - I show you how to analyze real problems, break them down into manageable chunks, come up with an algorithm, choose the right data structures, talk about the pros and cons… and only then code the solution.
