    "abstract": "We investigate how classical predictability of the coarse-grained evolution\nof the quantum baker\u0027s map depends on the character of the coarse-graining. Our\nanalysis extends earlier work by Brun and Hartle [Phys. Rev. D 60, 123503\n(1999)] to the case of a chaotic map. To quantify predictability, we compare\nthe rate of entropy increase for a family of coarse-grainings in the decoherent\nhistories formalism. We find that the rate of entropy increase is dominated by\nthe number of scales characterising the coarse-graining.",
