A Nonparametric Conjugate Prior Distribution for the Maximizing Argument of a Noisy Function
Pedro A. Ortega, Jordi Grau-Moya, Tim Genewein +2
We propose a novel Bayesian approach to solve stochastic optimization problems that involve finding extrema of noisy, nonlinear functions. Previous work has focused on representing…
Free Energy and the Generalized Optimality Equations for Sequential Decision Making
Pedro A. Ortega, Daniel A. Braun
The free energy functional has recently been proposed as a variational principle for bounded rational decision-making, since it instantiates a natural trade-off between utility gai…
Thermodynamics as a theory of decision-making with information processing costs
Pedro A. Ortega, Daniel A. Braun
Perfectly rational decision-makers maximize expected utility, but crucially ignore the resource costs incurred when determining optimal actions. Here we propose an information-theo…
Metabolic cost as an organizing principle for cooperative learning
David Balduzzi, Pedro A Ortega, Michel Besserve
This paper investigates how neurons can use metabolic cost to facilitate learning at a population level. Although decision-making by individual neurons has been extensively studied…
