Initialize PARAFAC algorithm input vectors
Usage
initializePARAFAC(Tensor, nfac, initialization = "random", output = "Fac")
Arguments
- Tensor
Input dataset matrix or tensor
- nfac
Number of components to initialize.
- initialization
Either "random" for random initialization or "svd" for svd based.
- output
Output the initialized components as a Fac object ("Fac", default) or as a vector ("vect").
Value
Fac or vector with initialized components.
Examples
A = array(rnorm(108,2), c(108,2))
B = array(rnorm(100,2), c(100,2))
C = array(rnorm(10,2), c(10,2))
Tensor = reinflateTensor(A, B, C, returnAsTensor=TRUE)
init = initializePARAFAC(Tensor, 2)
