SomeA popular distance measure such, cosine similarity/distance, is not a proper metricsmetric because it violatesfails to satisfy one of the rulesconditions (the triangle inequality). However, there is no disadvantage whatsoever byin using it and it is used heavily in many applicationapplications.

Is the categorization of a distance measure as a metric useful at all?
