What is Deep Learning and why is it such a popular buzzword in the machine learning field right now? For many years, until around , backpropagation neural networks had just three layers — one input, one hidden and one output layer. The problem with this model was that since it used gradient descent and the backpropagation algorithm, the neural nets had a tendency to be attracted towards the local minima in the hyperplane that represented the dimensions of the input features. Thus, NNs could not be used for many applications optimally, since they could only find a partially optimal solution. In , Geoffrey Hinton et. Deep learning refers to neural nets with 3 or more even 10 hidden layers.
