Example 1

A typical program to train a net may look like this:

loadNet("encoder.net")
loadPattern("encoder.pat")
setInitFunc("Randomize_Weights", 1.0, -1.0)
initNet()

while SSE > 6.9 and CYCLES < 1000 do
  if CYCLES mod 10 == 0 then 
    print ("cycles = ", CYCLES, "  SSE = ", SSE) endif
  trainNet()
endwhile

saveResult("encoder.res", 1, PAT, TRUE, TRUE, "create")
saveNet("encoder.trained.net")

print ("Cycles trained: ", CYCLES)
print ("Training stopped at error: ", SSE)

This batch program loads the neural net `encoder.net' and the corresponding pattern file. Now the net is initialized. A training process continues until the SSE error is smaller or equal to 6.9. The trained net and the result file are saved once the training is completed. The following output is generated by this program:

Net encoder.net loaded
Patternset encoder.pat loaded; 1 patternset(s) in memory
Init function is now Randomize_Weights
Net initialised
cycles = 0  SSE = 3.40282e+38
cycles = 10  SSE = 7.68288
cycles = 20  SSE = 7.08139
cycles = 30  SSE = 6.95443
Result file encoder.res written
Network file encoder.trained.net written
Cycles trained: 40
Training stopped at error: 6.89944
