curve_convergence

caf.toolkit.math_utils.curve_convergence(target, achieved)

Calculate the convergence between two curves.

Similar to r-squared, but weighted by the target values.

Parameters:

• target (ndarray) – A np.array listing y values on the curve we are aiming for

• achieved (ndarray) – A np.array listing y values on the curve we have achieved

Returns:

A float value between 0 and 1. Values closer to 1 indicate a better convergence.

Return type:

convergence

Raises:

ValueError: – If target and achieved are not the same shape
