ditionally, standard distances, like the euclidean distance, have been used to measure the data similarity. ... where M is a positive semide nite matrix, learning a distance reduces to learning the matrix M. This is equivalent to learning a linear map L. ... which contains numerical calculus libraries, such as NumPy, data processing li-braries ...

A further problem is that raw Euclidean distance is sensitive to the scaling of each constituent variable. For example, comparing persons across variables whose score ranges are dramatically different. Likewise, when developing a matrix of Euclidean coefficients by comparing multiple variables to one

1The term Euclidean Distance Matrix typically refers to the squared, rather than non-squared distances [1]. 2 It’s mentioned, for example, in the metric learning literature, e.g. [2]. Note that the computation of C assumes that the matrix library will perform broadcasting, which

When the initial distance of the robots is part of the input (i.e. no control), we show that simple algorithms exist which achieve optimal worst case evacuation times for the cases where: the robots begin colocated with an arbitrary distribution of the exits; and when the exits are either colocated or evenly spaced, with arbitrary starting ...
