If I understood, each row of the input matrix in the predict method contains the distances from a query point to each point in the training set. I think the reference should make this more clear. 2017-01-03 15:31 GMT-02:00 federico vaggi : > That would be most helpful. Maybe also explain the log

[scikit-learn] KNeighborsClassifier and metric='precomputed'

2017-01-02 Thread Pedro Pazzini
Hi all! I'm trying to use a KNeighborsClassifier with precomputed metric. In it's predict method (http://scikit-learn.org/stable/modules/generated/sklearn .neighbors.KNeighborsClassifier.html#sklearn.neighbors.KNeighborsClassifier.predict) it says the input should be: "(n_query, n_indexed) if met
