Explaining Human Choice Probabilities with Simple Vector Representations
Peter A. V. DiBerardino, Britt Anderson
We formalize human choice behavior in a probabilistic hide-and-seek task. In our geometric construction, vectors represent participant choice frequencies as well as probability mat…

Plinko: Eliciting beliefs to build better models of statistical learning and mental model updating
Peter A. V. DiBerardino, Alexandre L. S. Filipowicz, James Danckert +1
Prior beliefs are central to Bayesian accounts of cognition, but many of these accounts do not directly measure priors. More specifically, initial states of belief heavily influenc…

Minimal angle spread in the probability simplex with respect to the uniform distribution
Heinz H. Bauschke, Peter A. V. DiBerardino
We compute the minimal angle spread with respect to the uniform distribution in the probability simplex. The resulting optimization problem is analytically solved. The formula prov…
