Webb7 jan. 2024 · In information theory, Shannon entropy is one of the best known methodologies to measure the uncertainty. Therefore, whether there exists an information quality based on Shannon entropy is an interesting issue. Different from Gini entropy, the logarithm is not convergent and it is difficult to do linear operation. Webb29 mars 2024 · Tape a piece of paper to a hard floor, ensuring the paper doesn’t slip.
