lambda = 0.01, mu0 = NULL)
|
X |
The n x p binary matrix with samples along rows which we want to decompose using exponential family PCA. |
n_comp |
How many principal components should we return? |
n_cycle |
How many times should the iterative optimization pass through across each component? |
n_iter |
The maximum number of iterations to run the PCA. |
eps |
The convergence criterion. If the mean change in the scores is less than eps, we return. |
lambda |
The regularization parameter in the optimization. |
mu0 |
The value to regularize towards. |
A list containing the converged values of A and V.
