Deep Learning

What does a neuron compute?

• A neuron computes an activation function followed by a linear function (z = Wx + b)

• A neuron computes a linear function (z = Wx + b) followed by an activation function

• A neuron computes a function "g" that scales the input x linearly (Wx + b)

• A neuron computes the mean of all features before applying the output to an activation function

What is gradient descent?

• A way to determine how well the machine learning model has performed given the different values of each parameter
