The compound-cue model of cognitive control in task switching explains switch cost in terms of a switch of task cues rather than of a switch of tasks. The present study asked whether the model generalizes to Lag 2 repetition cost (also known as backward inhibition), a related effect in which the switch from B to A in ABA task sequences is costlier than is the same switch in CBA task sequences. ...

This paper presents the mechanism of Intelligent Adaptive Curiosity. This is an intrinsic motivation system which pushes the robot towards situations in which it maximizes its learning progress. It makes the robot focus on situations which are neither too predictable nor too unpredictable. This mechanism is a source of autonomous mental development for the robot: the complexity of its activitie...

Short duration tasks for text-independent speaker verification have received relatively little attention when compared to that directed at tasks involving many minutes of speech. In this paper we investigate verification performance on a range of durations from a few seconds to a few minutes. We begin with a state-of-the-art GMM-based system operating on a few minutes of speech per person and s...

We present a simple method for language independent and task independent text categorization learning, based on character-level n-gram language models. Our approach uses simple information theoretic principles and achieves effective performance across a variety of languages and tasks without requiring feature selection or extensive pre-processing. To demonstrate the language and task independen...

Scheduling a collection of tasks on a multiprocessor, consisting of p processors, that minimizes the maximum completion time has attracted a lot of attention in the literature [12]. In this paper, we introduce a new problem of scheduling a collection of independent tasks on a multiprocessor, called the partitionable independent task scheduling problem. Associated with each task, we are given th...

The last decade has witnessed major advances in core speech recognition technology,with today’s systems able to recognize continuous speech from many speakers without the need for an explicit enrollment procedure. Despite these improvements, speech recognition is far from being a solved problem. Most recognition systems are tuned to a particular task and porting the system to another task or la...

Perceptual learning (training-induced performance improvement) can be elicited by task-irrelevant stimulus exposure in humans. In contrast, task-irrelevant stimulus exposure in animals typically disrupts perception in juveniles while causing little to no effect in adults. This may be due to the extent of exposure, which is brief in humans while chronic in animals. Here we assessed the effects o...

In this paper we discuss some issues concerning the organization of knowledge for reuse and we critically examine the ideas of knowledge separation and minimal ontological commitments.. Because knowledge structures can play multiple roles in a domain, it is not necessarily the case that search-control knowledge can be neatly separated from a domain ontology. This is particularly the case when o...

Supplement Editor, Dr Flaura K Winston, and Co-Editor, Dr Teresa Senserrick, introduce 10 papers covering the current science of safe driving among adolescents from the varied viewpoints of an international panel of experts. This Expert Panel, convened by the Center for Injury Research and Prevention (formerly TraumaLink) at the Children's Hospital of Philadelphia and State Farm Insurance Compa...
