However, a possibly reasonable subgoal is that sensory information may be encoded efficiently in a population of neurons. In this context, Mutual Information is a long studied measure of coding efficiency, and many attempts to apply this to {\em population coding} have been made. However, this is a numerically intractable task, and most previous studies redefine the criterion in forms of an approximation to Mutual Information, the Fisher Information being one such well-known approach. Here we describe a principled bound maximisation procedure for Mutual Information learning of population codes in a simple point neural model, and compare it with other approaches.}, pdf = {https://publications.idiap.ch/attachments/reports/2004/agakov_barber_population04_idiap_rr.pdf}, postscript = {ftp://ftp.idiap.ch/pub/reports/2004/agakov_barber_population04_idiap_rr.ps.gz}, ipdmembership={learning}, }
