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. WebbShannon’s entropy metric helps identify that amount of storage needed for the information. One alternative way of looking at entropy is thus as a measure of “compressibility” of the …
