Hi all,
tldr: Is there a way for me to pass a 3D array to KNearestNeighbour?
I have constructed a custom distance metric to be used with KNN. It takes *two
2D arrays* and returns a float. I believe this fits the requirements for a
distance metric in sklearn.
However, I am unable to pass a 3D array to KNearestNeighbour. I get the
following error:
/Library/Python/2.7/site-packages/sklearn/neighbors/base.pyc in
_fit(self, X) 178 179 if X.ndim != 2:--> 180
raise ValueError("data type not understood") 181 182
n_samples = X.shape[0]
ValueError: data type not understood
Is there a way for me to pass a non 2D array to KNearestNeighbour? For
context, I'm implementing a 1NN with Dynamic Time Warping.
If not, is there a work around or a suggestion?
Many thanks
Mark
