I haven't seen any patch for this precisely, though it's a known issue (even if it doesn't seem to be explicitly ticketed; it's closest to https://github.com/scikit-learn/scikit-learn/issues/1179). There are various tricky cases not currently supported for which it's easiest to roll your own

[Scikit-learn-general] GridSearch with sample_weights

2013-05-31 Thread Peter Retzlaff
Hello everyone, I'm trying to execute a grid search with the GridSearchCV class (for an AdaBoostClassifier) and want to use a custom sample_weight vector to begin with. However, I can't figure out, how to do this. Passing the parameter to GridSearchCV's fit()-method gives me the message, that
