Compute T_hat = Gamma_test %*% W_hat.
Usage
item_predict(Gamma_test, W_hat)
Arguments
- Gamma_test
Numeric matrix (n_test x n_features).
- W_hat
Numeric matrix (n_features x p).
Value
Numeric matrix of predictions (n_test x p).
Examples
Gamma_test <- matrix(c(1, 0, 0, 1), ncol = 2, byrow = TRUE)
W_hat <- diag(2)
item_predict(Gamma_test, W_hat)
#> [,1] [,2]
#> [1,] 1 0
#> [2,] 0 1
