Weights

• The inputs can be modified by weights. (This also adds a similarity to biological neural nets.)
• Now we can change the weights to change the system.
• 
• Let's use a step function.
• The input output pairs are ((5,7), 1), ((3,10), 0), ((5,10),1), and ((5,2),0)
• If the threshold is 0, and the weights are both 1, the outputs are all 1.
• If we move the threshold to 12, the last ouput is 0, and the first three are 1. We want the second to be 0.
• If we change the second weight to .5 and the threshold to 8.2, it gives the correct result.
