Information-Seeking Decision Strategies Mitigate Risk in Dynamic, Uncertain Environments
Nicholas W. Barendregt, Joshua I. Gold, Krešimir Josić +1
To survive in dynamic and uncertain environments, individuals must develop effective decision strategies that balance information gathering and decision commitment. Models of such…
Adaptive Bayesian Inference of Markov Transition Rates
Nicholas W. Barendregt, Emily G. Webb, Zachary P. Kilpatrick
Optimal designs minimize the number of experimental runs (samples) needed to accurately estimate model parameters, resulting in algorithms that, for instance, efficiently minimize…
Heteroclinic cycling and extinction in May-Leonard models with demographic stochasticity
Nicholas W. Barendregt, Peter J. Thomas
May and Leonard (SIAM J. Appl. Math 1975) introduced a three-species Lotka-Volterra type population model that exhibits heteroclinic cycling. Rather than producing a periodic limit…
Analyzing dynamic decision-making models using Chapman-Kolmogorov equations
Nicholas W. Barendregt, Krešimir Josić, Zachary P. Kilpatrick
Decision-making in dynamic environments typically requires adaptive evidence accumulation that weights new evidence more heavily than old observations. Recent experimental studies…
