Example #1

File: test_gradient.py Project: mushketyk/pybrain

 def _createNegativeOptimizer(self, startParams):
     optimizer = GradientOptimizer(negativeParabaloidEvaluator, startParams, negativeDerivativesCalculator)
     optimizer.maxLearningSteps = 200
     optimizer.minimize = False
     
     return optimizer
