select_observed_from_LR: select_observed_from_LR

In namgillee/BTTSoftImpute: R Software for Block Tensor Train Decomposition for Missing Data Estimation

Description

Select observed values randomly from data x. Here, 'randomly' means uniform random sampling.

Usage

select_observed_from_LR(x, numobs = NULL, rate = 1)

Arguments

x	A data matrix in LR (Low-rank (SVD)) format with attributes $u, $d, $v. $u is a matrix, x$v is a blockTT format.
numobs	Number of observed values to select.
rate	If numobs==NULL, then numobs = rate * numels(full(x)).

Value

The returned value is a SparseMatrix format, with attributes $i, $j, $v, $nrow, $ncol, $dimnames.
