Talk Title: The Unpredictable, the Predetermined, and the Postdetermined Unfold Together

Abstract: Recently, decomposition of the Shannon entropy rate has been proposed which provided a more nuanced understanding of entropy generation in a variety of systems. One component of this decomposition, the ephemeral information, is the part of the entropy rate which is independent of the future behavior of the system. The other component, the bound information, is that which plays a role in the dynamics going forward. Having derived this decomposition, I will then use it to characterize the effects of generating partition choice on chaotic systems, namely the tent map. Though all generating partitions result in a bijection between map orbits and symbolic sequences, the information-theoretic properties of such symbolic sequences can be very different as exemplified by the ephemeral and bound informations.

Biography: I did my doctoral work with Jim Crutchfield at UC Davis physics department. I then did a postdoc with Liz Bradley at CU Boulder, and am now doing my second postdoc back at Davis with Jim Crutchfield.
