Global Bigdata Conference

Describing deep learning as a black box is not meant to denigrate the practice. After, all, we're thrilled that, when we build a convolutional neural network with hundreds of input variables and more than a thousand hidden layers (as the biggest CNNs are), it just works. We don't exactly know how it works, but we're grateful that it does work. If we had we been required to explicitly code a program to do the same thing as the CNN does, it likely would be a complete disaster. We simply could not build the decision-making systems we're building today without the benefit of self-learning machines.
