Shannon entropy metric
WebbWe define hμ = sup ξ hμ ( ξ) as the metric entropy of the random dynamical system, where the supremo is taken over all μ -measurable partitions. An important point here is the following notion: setting the Borel σ -algebra of M, we say that a finite partition ξ of M is a random generating partition for if. WebbThe Jensen–Shannon divergence (JSD) is a symmetrized and smoothed version of the Kullback–Leibler divergence . It is defined by where . The geometric Jensen–Shannon …
