Let G be a real noncompact semi-simple Lie group with finite center and K a maximal compact sub-group. The symmetric space M = G/K carries a measure invariant under the action of G. The operators which map L(p)(M) continuously into itself and commute with the action of G, can be easily characterized when p = 2 or p = 1. This note gives some results on "singular integrals" which map L(p) into it...

For robots to become prevalent in human environments, the robots need to be able to perform complex tasks often involving sequential repetition of actions. In this work, we present a demonstrationbased approach to teach a robot generalized plans for performing sequential tasks with repetitions. We introduce action definitions through perception. Using the action definitions and the demonstratio...

Here we review the literature examining the perceptual, attentional, and cognitive benefits of playing one sub-type of video games known as ‘action video games,’ as well as the mechanistic underpinnings of these behavioral effects. We then outline evidence indicating the potential usefulness of these commercial off-the-shelf games for practical, real-world applications such as rehabilitation or...

In this paper we use a computer model of social capital to explore and develop a computational social theory of the anthropological or interpretive notion of the sub jectivity (Ortner 2005). The cultural sub jectivity is a social theory of the reflexive actor that is historically situated in a material and cultural context. It is important for computational social science to begin developing to...

T paper presents a new randomized search method called evolutionary random policy search (ERPS) for solving infinite-horizon discounted-cost Markov-decision-process (MDP) problems. The algorithm is particularly targeted at problems with large or uncountable action spaces. ERPS approaches a given MDP by iteratively dividing it into a sequence of smaller, random, sub-MDP problems based on informa...

The control and coordination of multiple mobile robots is a challenging task; particularly in environments with multiple, rapidly moving obstacles and agents. This paper describes a robust approach to multi-robot control, where robustness is gained from competency at every layer of robot control. The layers are: (i) a central coordination system (MAPS), (ii) an action system (AES), (iii) a navi...

Physics Playground is an educational game that supports physics learning. It accepts multiple solutions to most problems and does not impose a stepwise progression through the content. Assessing student performance in an open-ended environment such as this is therefore challenging. This study investigates the relationships between student action sequences and affect among students using Physics...

For most decision making problems, finding representative parameters of a decision maker’s preferences remains a challenging task. We here adapt to the Promethee II outranking method an eliciting procedure named Q-Eval that has been developed in the context of multi-attribute utility. It refines the estimation of the preference parameters by iteratively querying the DM through pairwise action c...
