New Bounds Set for Rényi and Min-Entropy Estimation

Researchers have established new sample complexity bounds for estimating Rényi and min-entropy, which are fundamental concepts in information theory and property testing. The study provides precise characterizations for the number of samples required to accurately estimate these entropy measures for a k-symbol alphabet. Notably, min-entropy estimation requires significantly more samples than Shannon entropy, with a sample complexity of \Theta(k \log k), correcting previous assumptions. AI
