Assignment 1
Use
MATLAB NEURAL NETWORKS TOOLBOX
or the
Neunet (Desire)
system to develop several variations of single-layer feed-forward networks that are able to learn sets of patterns. A set of patterns is learned if the TSS becomes zero. Note it may not be possible to learn a particular set of patterns
1. The basic single-layer feed-forward (SLFF) program uses a threshold activation function and the Delta learning rule. Try to learn (a) the AND patterns, (b) the
OR patterns, (c) the XOR patterns.
2. Change the threshold activation function into a linear activation function. Then, repeat the three parts of Question 1 using the linear activation function.
3. Change the linear activation function into a sigmoid activation function. Then, repeat the three parts of Question 1 using the sigmoid activation function.
