Question

is the cosine distance equal to the cosine of the angle ?

Answer 1

They aren't equal,
Compare their formulas

Answer 2

\(CD = 1- \dfrac{u.v}{||u||~||v||}

\\ \cos \theta = \dfrac{u.v}{||u||~||v||} \)

Answer 3

so probably you can say
Cosine Distance = 1- cos of the angle between them

Answer 4

and another name for cos theta is cosine similarity

so, cosine distance = 1- cosine similarity

Answer 5

Cosine described below is a relationship between the hypotenuse \(c\) of a right triangle and \(a\)


Think of cosine as relating the "horizontal" component of c, while sine relates to c's vertical component.

Hope this helps.
