We propose a multivariate decision tree inference scheme by using the minimum message length (MML) principle (Wallace and Boulton, 1968; Wallace and Dowe, 1999). The scheme uses MML coding as an objective (goodness-of-fit) function on model selection and searches with a simple evolution strategy. We test our multivariate tree inference scheme on UCI machine learning repository data sets and com...

This paper investigates the impact of sequential selection, a concept recently introduced for Evolution Strategies (ESs). Sequential selection performs the evaluations of the different candidate solutions sequentially and concludes the iteration immediately if one offspring is better than the parent. In this paper, the (1,4)-CMA-ES, where sequential selection is implemented, is compared on the ...

Selecting a suitable conflict resolution strategy when conflicts appear in multi-agent environments is a hard problem. There is a need to develop a method that can select a suitable strategy which guaranties low cost in terms of the number of messages and time ticks. This paper focuses on conflicts over agents’ individual opinion and decision making by taking into account an agent’s features su...

The effect of problem format on problem solving strategy selection is investigated within the early algebra domain of functional thinking. Functional Thinking is a type of algebraic reasoning appropriate for elementary students, in which a relationship exists between two sets of values. Three function table problems were given to students in grades two through six (N=232) in three different pro...

Selecting a suitable conflict resolution strategy when conflicts appear in multi-agent environments is a hard problem. There is a need to formulate a model for strategic decision making in selecting a strategy to resolve conflicts. In this paper, we formalise a model for selecting a conflict resolution strategy in multi-agent systems. The model is expected to select a suitable strategy which gu...

Purpose: Our goal was to determine the effectiveness of a brief online intervention designed to reduce stigma-relevant attitudes toward mentally ill individuals. We examined whether the experience of completing a Brief Implicit Association Test (BIAT) measuring attitudes toward people with mental illnesses alters explicit stigma in two studies. Methods: In Study 1, participants completed the BI...
