Detailed Description

template<class T>
class ReservoirSGD< T >

This class extends IncrementalSGD and implements ReservoirSGD.

This means that during the training we use a reservoir with the size r. First, we use given training examples to fill reservoir. Then, at each iteration, we randomly replace an example with the given training example in the reservoir and then train the model with the all elements in the reservoir
