fa_like {LRMF3} | R Documentation |
Create a Factor Analysis-like low rank matrix factorization object
Description
A low rank matrix factorization of a matrix X
is
parameterized by X ~= X %*% B %*% t(Y)
. The
object is "factor analysis-like" because the middle
matrix in the decomposition is arbitrary rather than
diagonal.
Usage
fa_like(Z, B, Y, subclasses = NULL, ...)
Arguments
Z |
A matrix of embeddings for each observation. |
B |
A mixing matrix describing how observation embeddings and topics interact. Does not have to be diagonal! |
Y |
A matrix describing the compositions of various topics or factors. |
subclasses |
A character vector of subclasses.
Optional, defaults to |
... |
Optional additional items to pass to the constructor. |
Examples
s <- svd(as.matrix(trees))
fa_like(s$u, diag(s$d), s$v)
