Hi,
I'm trying to understand the output of cv_validation_scores, when running a
GridSearchCV. The documentation does not adequately explain this.
When I print grid_search.grid_scores_, I get a list with items like this:
[mean: 0.60000, std: 0.18002, params: {'tfidf__binary': True,
tfidf__ngram_range': (1, 1)....
which makes sense. However, when I try to unpack each instance of
grid_scores, I get
[0] same dictionary as above, makes sense
[1] score for all folds, makes sense
[2] a list that I don't understand, that looks like "[ 0.75
0.33333333 0.66666667]"
What are the scores being reported here?
Thanks,
Adam
