Understanding of Neural nets from first-principles: Brain dump So I was reading my company’s IT newsletter the other day where one of the topics was sparse modeling (discussing this Forbes article) and it got me thinking again about some things I was reading the past months, about trying to understand how and why (mainly) Deep Learning works. First-principles In a way, sure we know how it works on the microscopic level of each individual neuron (activation functions, matrix multiplications, gradient descent and all that), and we also often describe it at a high level (where we tend to greatly anthropomorphize it: “the model learned to do X because in all its examples it saw this object from the same angle, ....
