Iterative(gdml_train, desc, max_memory, max_processes, use_torch, callback=None)[source]¶
_cho_factor_stable(M, pre_reg=False, eps_mag_max=1)[source]¶
Performs a Cholesky decompostion of a matrix, but regularizes as needed until its positive definite.
numpy.ndarray) – Matrix to factorize.
pre_reg (boolean, optional) – Regularize M right away (machine precision), before trying to factorize it (default: False).
numpy.ndarray– Matrix whose upper or lower triangle contains the Cholesky factor of a. Other parts of the matrix contain random data.
boolean – Flag indicating whether the factor is in the lower or upper triangle
