In hemberg-lab/scmap: A tool for unsupervised projection of single cell RNA-seq data
Description
Computes the dot product between the subcentroids from the indexed reference and the subvectors of an element of the query dataset.
Returns an M by k matrix. Used as an intermediate step (in NNfirst and NNmult) for calculating
an approximation of the cosine similarity between the query and the reference.
Usage
1
subdistsmult(subcentroids, query_chunks, M, k, cellnum)
Arguments
subcentroids
A list of matrices containing the subcentroids of each chunk.
query_chunks
A list of matrices containing the chunks of the query dataset after it has been split
according to the product quantization method
M
An integer specifying the number of chunks
k
An integer specifying the number of subcentroids per chunk
cellnum
An integer specifying the column of the query dataset we wish to consider
