Assignment 2 Use
MATLAB NEURAL NETWORKS TOOLBOX or the
Neunet (Desire) system to study Learning in single-layer feed-forward networks.
1. Use
linear activation function and
Hebbian learning fora SLFF network to attempt to learn the following two sets of patterns. Why
can the patterns be learned, or why can they not be learned Input Output
1 0 0 0 1 Set (1)
0 1 0 1 0 0 0 1 1 1 1 0 0 0 1 Set (2)
0 1 0 1 0 1 1 1 1 1 2. Repeat Question 1 using the
linear activation function, but with
Delta learning rule instead of Hebbian learning rule (remember that in the first assignment also you used Delta learning rule. Why can the patterns be learned, or
why can they not be learned 3. Use
sigmoid activation function and the
Delta learning rule. Try to learn (a) the
