1.2.a Discrete-time signals Discrete-time signals Discrete-time signal:= A sequence of complex numbers Dimension = 1 (for now) Notation: where is an integer Two-sided sequences: is one-dimensional “time”. Analysis: Periodic measurement approach Discrete-time signals can be created by an analysis process where we take periodic measurements of a physical phenomenon. Synthesis: Stream of generated samples Delta […]

Lecture 6 | Training Neural Networks I Sigmoid Problems of the sigmoid activation function Problem 1: Saturated neurons kill the gradients. Problem 2: Sigmoid outputs are not zero-centered. Suppose a given feed-forward neural network has hidden layers and all activation functions are sigmoid. Then, except the first layer, the other layers get only positive inputs. […]
