What is Machine Learning?
Machine Learning, Deep Learning, and Neural Networks are all essential components of one another, so to understand Neural Networks, we have to start with Machine Learning. If you imagine the Russian doll "Matryoshka", it's all quite similar to that. Let's say Artificial Intelligence is the biggest doll, that holds inside of her a smaller one called Machine Learning, that one holds in the Deep Learning and the smallest one is the Neural Network toy – the heart (brain) of everything.
So what is Machine Learning? Very generally speaking – Machine Learning is learning from examples. We give our machine as many examples as we can and the machine learns from those examples as long as it can classify and distinguish things correctly as we've taught it.
