[scikit-learn] no positive predictions by neural_network.MLPClassifier

[Thomas Evangelidis]

I tried the sklearn.neural_network.MLPClassifier with the default
parameters using the input data I quoted in my previous post about
Nu-Support Vector Classifier. The predictions are great but the problem is
that sometimes when I rerun the MLPClassifier it predicts no positive
observations (class 1). I have noticed that this can be controlled by the
random_state parameter, e.g. MLPClassifier(random_state=0) gives always no
positive predictions. My question is how can I chose the right random_state
value in a real blind test case?

thanks in advance
Thomas
