SUMMARY:CSH Talk by David Wolpert: "Uncertainty relations and fluctuation theorems for Bayes nets"
DESCRIPTION:[vc_row][vc_column width=”1/6″][/vc_column][vc_column width=”2/3″][vc_column_text] \n\n\n\nThe lecture by David Wolpert from Santa Fe Institute will take place at the Complexity Science Hub Vienna.\n \nRoom: Salon\n\n\n\n \nIf you are interested in participating\, please email to office@csh.ac.at.\n \n \nAbstract:\n \nThe pioneering paper “Information Thermodynamics on Causal Networks” by Sosuke Ito and Takahiro Sagawa (2013) analyzed the non-equilibrium statistical physics of a set of multiple interacting systems\, S\, whose joint discrete-time evolution is specified by a Bayesian network. The major result of Ito and Sagawa was an integral fluctuation theorem (IFT) governing the sum of two quantities: the entropy production (EP) of an arbitrary single one of the systems\, v in the set S\, and the transfer entropy from v to the other systems. \n \nHere I extend the analysis in Ito and Sagawa’s paper. I derive several detailed fluctuation theorems (DFTs)\, concerning arbitrary subsets of all the systems (including the full set). I also derive several associated IFTs\, concerning an arbitrary subset of the systems\, thereby extending Ito/Sagawa’s IFT. In addition\, I derive “conditional” DFTs and IFTs\, involving conditional probability distributions rather than—as in conventional fluctuation theorems—unconditioned distributions. I then derive thermodynamic uncertainty relations relating the total EP of the Bayes net to the set of all the precisions of probability currents within the individual systems. \n \n \n \n[/vc_column_text][/vc_column][vc_column width=”1/6″][/vc_column][/vc_row] \n
