Converts cosine distance to cosine similarity in [-1, 1].
Usage
cosine_to_similarity(distance)
Arguments
- distance
Numeric. Cosine distance value(s).
Value
Numeric cosine similarity score(s), where 1 means the same direction,
0 means orthogonal, and -1 means opposite directions.
Examples
# Distance of 0 -> similarity of 1
cosine_to_similarity(0) # Returns 1
#> [1] 1
# Distance of 0.5 -> similarity of 0.5
cosine_to_similarity(0.5) # Returns 0.5
#> [1] 0.5
