SparseVector

SparseVector is an n-dimension sparse vector.

Very simple implementation with just the functions I needed at the time for Lunrelm.

Model stored in Dict with index as key.

Dimension of vector is not held, so there is no way to check that dot or cosineSimilarity are both using the same dimension vector.

type alias SparseVector =

Dict Int Float

SparseVector type alias

empty : SparseVector

Empty SparseVector

isEmpty : SparseVector -> Bool

Return true if vector is empty

insert : Int -> Float -> SparseVector -> SparseVector

Insert value in vector.

insertList : List ( Int, Float ) -> SparseVector -> SparseVector

Insert list of values in vector.

magnitude : SparseVector -> Float

Calculates magnitude of vector.

Sqrt of Sum of Squares of each dimension value.

dot : SparseVector -> SparseVector -> Float

Calculates the dot product between vectors.

cosineSimilarity : SparseVector -> SparseVector -> Float

Calculates the cosine similarity between vectors.
