perceptron_test():
  MATLAB/Octave version 9.8.0.1380330 (R2020a) Update 2
  Test the perceptron algorithm.

  Data file: index, rpm, vibration, rating
  Rating is 0 for bad, 1 for good.
  Use the perceptron algorithm to determine a
  classifier f(rpm,vibration) -> {0, 1}

  Generator Ratings

  Number of generators = 56
  28 good generators, and 28 bad generators
  562 <= RPM <= 939
  79 <= VIB <= 585
  GOOD: mean RPM = 740.75, mean VIB = 447.286
  BAD:  mean RPM = 741.964, mean VIB = 219.857
  79 <= VIB <= 585
