PycudaDistances

Fast python distance computations in a variety of metrics that uses Graphics Processing Units with PyCuda.

This is a framework that will allow general distance metrics to be incorporated into tree-based neighbors searches. The idea is that we need a fast way to compute the distance between two points under a given metric.

Usage

>>> from pycudadistances.distances import euclidean_distances
>>> X = [[0, 1], [1, 1]]

>>> euclidean_distances(X, X)
array([[ 0.,  1.],
       [ 1.,  0.]])

>>> # get distance to origin
>>> euclidean_distances(X, [[0, 0]])
array([[ 1.        ],
       [ 1.41421356]])
