Over long lifetimes, learning agents accumulate large stores of knowledge. To support human-level decision-making, their cognitive architectures must efficiently manage this experience and bring to bear pertinent data to act in the world.Prior psychological and computational work suggests the need for multiple, dissociated memory systems, citing significant functional and computational tradeoff...

In this paper, we examine teleoperation as a critical aspect of using mobile robotic telepresence systems. Particularly, we propose and advocate using cognitive architectures as means to ease teleoperation for novice users and to enhance social interactions.

The traditional consideration that intelligent behaviors can only be produced from pure reasoning fails when trying to explain most of human behaviors, in which the emotional component has a decisive weight. However, the inclusion of this kind of emotional factors charges agent architectures with an extra complexity, making them less efficient or reusable. This paper presents a generic cognitiv...

The rapid proliferation of wireless communications has brought many exciting new technologies that require ever more spectrum. A recent FCC study noted that spectrum utilization exhibits large geospatial and temporal variances. As the number of wireless devices requiring spectrum access will undoubtedly increase, much effort has gone into exploiting the results from this study. The current stra...

The computer metaphor has served brain science well as a tool for comprehending neural systems. Nevertheless, we propose here that this metaphor be replaced or supplemented by a new metaphor, the "Internet metaphor," to reflect dramatic new network theoretic understandings of brain structure and function. We offer a "weak" form and a "strong" form of this metaphor: The former suggests that stru...

The Cognitive Theory of True Conditions (CTTC) is a proposal to design the implementation of cognitive abilities and to describe the modeltheoretic semantics of symbolic cognitive architectures. The CTTC is formulated mathematically using the multi-optional many-sorted past present future(MMPPF) structures. This article discussed how decision-making processes are described in the CTTC.

While cognitive architectures provide excellent infrastructure for research stretching over various fields, the integrated nature consisting of multiple modules makes their evaluation extremely difficult. Due to the lack of analytical criteria, the cost of general demonstrations, and varying specifications among different architectures, deriving any general evaluation methods is a complicated t...

The question whether connectionism offers a new way of looking at the cognitive architecture, or if its main contribution is as an implementational account of the classical (symbol) view, has been extensively debated for the last decade. Of special interest in this debate has been to achieve tasks which easily can be explained within the symbolic framework, i.e., tasks which seemingly require t...

The world itself is a very complex place for architecture agents to act in. The real world is partially observable, stochastic, sequential, dynamic and continuous. Most architecture is designed to only deal with fractions of the total possible environmental complexity by acting in particular domains. For example, some architecture assumes that the world is static and that the only things that c...

It is generally accepted that an integrated cognitive architecture is required to fully explain complex functions of the brain such as learning and behavior. However, typical architectures do not include a theory of emotion. This article proposes a framework of emotion suitable for inclusion in an integrated architecture and examines the impact of arousal on memory and how a particular architec...
