Uses of Similarity in de.aitools.aq.algebra.vector.functions

Classes in de.aitools.aq.algebra.vector.functions that implement Similarity
`class`	`CosineSimilarity` A `Similarity` measure for `Vector`s. The Cosine Similarity of two vectors is defined as the cosine of the angle between them. It is calculated as the dot product of the both vectors divided by the multiplied euclidean norms of both. The resulting similarity of a vector a and a vector b is between -1 (if a equals -b k) and 1 (if a equals b k), with k being a positive rational number (and thus not zero).

class CosineSimilarity
A Similarity measure for Vectors.
The Cosine Similarity of two vectors is defined as the cosine of the angle between them.
It is calculated as the dot product of the both vectors divided by the multiplied euclidean norms of both.
The resulting similarity of a vector a and a vector b is between -1 (if a equals -b * k) and 1 (if a equals b * k), with k being a positive rational number (and thus not zero).
