Rényi & Tsallis Entropy

Explore generalized entropy families. Drag the distribution sliders to shape the probability distribution, and watch how Rényi (order q) and Tsallis (index q) compare to Shannon entropy.

Rényi entropy: H_q = log(Σpᵢq)/(1-q). Tsallis entropy: S_q = (1-Σpᵢq)/(q-1). Both → Shannon entropy as q→1. Rényi q=0: log(support size); q=2: collision entropy; q=∞: min-entropy. Used in multifractals, anomalous diffusion (Tsallis), and quantum information.
