Good recognition is non-metric: true or false?

If the relations between the objects to be recognized are non-metric, there seems to be something wrong. However, Walter Scheirer and his co-authors claim in the  August issue of Pattern Recognition that “Good recognition is non-metric“, [1]:  Is this statement true or false? See also one of the webpages of Walter Scheirer. Readers of this…

Non-Euclidean embedding

Non-Euclidean dissimilarities may arise naturally when we want to build a measure that incorporates important knowledge about the objects. This is fine, but how to embed such dissimilarities in a vector space if we want to use the standard linear algebra tools for generalization? Here the so-called pseudo-Euclidean vector space will be discussed. To understand…
