What is Firing Rule
A firing rule determines how one calculates whether a neuron should fire for any input pattern.
What is Perceptron
First neural network with the ability
to learn
Made up of only input neurons and
output neurons
Output neurons use a simple
Threshold activation function
Learning in ANN
Only supplies inputs
► The neural network
adjusts its own weights so
that similar inputs
Cause similar outputs
Back Propagation Algorithm
Most common method
of obtaining the many
weights in the networkz
based on minimizing the
error of the network using
the derivatives of the error
function
