I'm using a spreadsheet to train a perceptron to make music recommendations based upon other people who have heard the music. 0 = hasn't heard, 1 = recommended, -1 = not recommended.

When calculating the output using an equation such as: IF(SUM>THRESHOLD, 1, 0) how do we take into consideration 1 and -1 and what would we set the threshold too? Its all very vague to me.

I'm using the following info similar to the example on wikipedia:

CODE

th    lr    x0    x1    x2    z    w0    w1    w2    sum    n    e    r    w0    w1    w2
0    0.1    -1    1    1    1    0    0    0    0    -1    2    0.2    -0.2    0.2    0.2
0    0.1    1    0    0    -1    -0.2    0.2    0.2    -0.2    -1    0    0    0    0    0
0    0.1    -1    1    0    1    0    0    0    0    -1    2    0.2    -0.2    0.2    0
0    0.1    0    -1    -1    -1    -0.2    0.2    0    -0.2    -1    0    0    0    0    0
0    0.1    1    -1    -1    -1    0    0    0    0    -1    0    0    0    0    0
0    0.1    0    1    1    1    0    0    0    0    -1    2    0.2    0    0.2    0.2
0    0.1    0    -1    -1    -1    0    0.2    0.2    -0.4    -1    0    0    0    0    0
0    0.1    -1    0    0    1    0    0    0    0    -1    2    0.2    -0.2    0    0
