If metric is a string, it must be one of the options allowed by scipy.spatial.distance.pdist for its metric parameter, or a metric listed in pairwise.PAIRWISE_DISTANCE_FUNCTIONS. If metric is “precomputed”, X is assumed to be a distance matrix.

Websklearn.metrics.pairwise.haversine_distances(X, Y=None) [source] ¶ Compute the Haversine distance between samples in X and Y. The Haversine (or great circle) distance is the angular distance between two points on the surface of a sphere. The first coordinate of each point is assumed to be the latitude, the second is the longitude, given in radians. Distance matrix computation from a collection of raw observation vectors stored in a rectangular array. Predicates for checking the validity of distance matrices, both condensed and redundant. Also contained in this module are functions for computing the number of observations in a distance matrix. WebThe distances between the row vectors of X and the row vectors of Y can be evaluated using pairwise_distances. If Y is omitted the pairwise distances of the row vectors of X are calculated. Similarly, pairwise.pairwise_kernels can be used to calculate the kernel between X and Y using different kernel functions. toiyabe golf club washoe valley
