Compute Cosine Similarity
Usage
topic_similarity(x, y = NULL)
Arguments
- x
Numeric embedding matrix, or one numeric vector.
- y
Optional second embedding matrix or vector. When omitted, computes
all pairwise similarities among rows of `x`.
Value
A numeric similarity matrix.
Examples
x <- rbind(c(1, 0), c(0, 1), c(1, 1))
topic_similarity(x)
#> [,1] [,2] [,3]
#> [1,] 1.0000000 0.0000000 0.7071068
#> [2,] 0.0000000 1.0000000 0.7071068
#> [3,] 0.7071068 0.7071068 1.0000000
