Property Value

The distance function that computes the distance between a new data point x and the reference data point x_i. The first parameter is the new data point x. The second parameter is the reference data point x_i. The third parameter is the index i of the reference data point x_i. (The third parameter can be ignored in most cases.)

The default distance function computes the Euclidean distance between x and x_i.

(The distance function could be generalized to the Mahalanobis distance.)
