sink {expperm} | R Documentation |
A variational approximation of an expected permutation matrix
Description
Computes an approximate expected permutation matrix and marginal likelihood from a matrix of assignment likelihoods. The approximation minimizes a constrained KL divergence from the likelihood, and is computed via the repeated renormalization of the input's rows and columns.
Usage
sink(A, maxit = 99, return.permanent.bound = FALSE)
Arguments
A |
A matrix of assignment likelihoods. |
maxit |
An integer specifying the maximum number of steps used in the optimization. |
return.permanent.bound |
A logical value indicating whether the function should also return an upper bound on the permanent of |
Value
E(P)
, the expected permutation matrix corresponding to A
.
