Fawcett (http://www.hpl.hp.com/techreports/2003/HPL-2003-4.pdf) discusses multi-class ROC curves briefly and cites Hand, D. J., & Till, R. J. (2001). A simple generalization of the area under the ROC curve to multiple class classification problems. Machine Learning, 45 (2), 171–186. That might be a

[Scikit-learn-general] Unexpected behavior using numpy.asarray with RandomForestClassifier

2014-05-23 Thread Steven Kearnes
If I try to do something like: import numpy as np from sklearn.ensemble import RandomForestClassifier X = np.random.random((100, 10)) y = np.random.randint(2, size=100) estimator = RandomForestClassifier() estimator.fit(X, y) a = np.asarray([estimator]) a is a list of the individual DecisionTre
