Modeling Statistical Insensitivity: Sources of Suboptimal Behavior

Modeling Statistical Insensitivity: Sources of Suboptimal Behavior

Children acquiring languages with noun classes (grammatical gender) have ample statistical information available that characterizes the distribution of nouns into these classes, but their use of this information to classify novel nouns differs from the predictions made by an optimal Bayesian classifier. We use rational analysis to investigate the hypothesis that children are classifying nouns o...

Suboptimal choice behavior by pigeons.

Contrary to the law of effect and optimal foraging theory, pigeons show suboptimal choice behavior by choosing an alternative that provides 20% reinforcement over another that provides 50% reinforcement. They choose the 20% reinforcement alternative--in which 20% of the time, that choice results in a stimulus that always predicts reinforcement, and 80% of the time, it results in another stimulu...

Statistical Analysis of Data for Modeling The Behavior

In this work statistical analyses were used in order to model the behavior of a protection relay and to investigate relationships among variables affecting the functioning of the tested software. The objective was to test the performance of the protection relay under high load. The results showed that statistical analyses were particularly a useful means for modeling the behavior of software, w...

When Suboptimal Behavior is Optimal and Why: Modeling the Acquisition of Noun Classes in Tsez

Children acquiring languages with noun classes (grammatical gender) have ample statistical information available that characterizes the distribution of nouns into these classes, but their use of this information to classify novel nouns differs from the predictions made by an optimal Bayesian classifier. We propose three models that introduce uncertainty into the optimal Bayesian classifier and ...
