algorithm_functions.inverse_logistic_transformation_matrix(Matrix: ndarray, ALGORITHM_PARAMETERS: dict[str, Any]) → ndarray#

Calculates the inverse logistic transformation of a matrix.

If the matrix contains 0 or 1 values, they are first set to the values INVERSE_ZERO and 1-INVERSE_ZERO, respectively, to avoid computational problems due to the use of the natural logarithm. The inverse function is equal to \(ln(x/(1-x))\) for input \(x\).

Parameters:

  • Matrix (np.ndarray) – The matrix that is inversely transformed.

  • ALGORITHM_PARAMETERS (dict[str, Any]) – The algorithm parameters. The parameter INVERSE_ZERO is at least necessary. See main.py for parameter explanations.

Returns:

transformed_matrix (np.ndarray) – The inversely transformed matrix.
