pytc.legacy.df.test_accuracy(rho_orig, C, P)[source]¶

Calculate reconstruction relative and absolute errors.

Parameters:

rho_orig (numpy.ndarray) – Original tensor (N_b, N_grid, *trailing_dims)
C (numpy.ndarray) – Selected columns (N_b, n_rank, *trailing_dims)
P (numpy.ndarray) – Interpolation coefficients (n_rank, N_grid, *trailing_dims)

Returns:

Relative error of reconstruction abs_error: Absolute error of reconstruction

Return type:

rel_error
