Logic, self-awareness and self-improvement: The metacognitive loop and the problem of brittleness

This essay describes a general approach to building perturbation-tolerant autonomous systems, based on the conviction that artificial agents should be able notice when something is amiss, assess the anomaly, and guide a solution into place. We call this basic strategy of self-guided learning the metacognitive loop; it involves the system monitoring, reasoning about, and, when necessary, altering its own decision-making components. In this essay, we (a) argue that equipping agents with a metacognitive loop can help to overcome the brittleness problem, (b) detail the metacognitive loop and its relation to our ongoing work on time-sensitive commonsense reasoning, (c) describe specific, implemented systems whose perturbation tolerance was improved by adding a metacognitive loop, and (d) outline both short-term and long-term research agendas

But next time, I will win: On the relation between irrationality and probability estimates in a game of chance

Based on Rational Emotive Behavior Therapy (REBT) we tested the hitherto unexplored assumption that irrationality as conceptualized by REBT (demandingness, self evaluation, low frustration tolerance), is associated with erroneous statistical reasoning. We assessed trait irrationality of 216 respondents and individual estimates of future winning probabilities in the context of the Wortman (1975) perceived control design. Results indicate that an increased (i.e., unrealistically optimistic) as well as a decreased (i.e., unrealistically pessimistic) estimation of future winnings is associated with irrationality. Findings substantiate an association between erroneous probability estimates and therapeutically relevant cognitions which do not imply any mathematical or statistical contents

A fault-tolerant intelligent robotic control system

This paper describes the concept, design, and features of a fault-tolerant intelligent robotic control system being developed for space and commercial applications that require high dependability. The comprehensive strategy integrates system level hardware/software fault tolerance with task level handling of uncertainties and unexpected events for robotic control. The underlying architecture for system level fault tolerance is the distributed recovery block which protects against application software, system software, hardware, and network failures. Task level fault tolerance provisions are implemented in a knowledge-based system which utilizes advanced automation techniques such as rule-based and model-based reasoning to monitor, diagnose, and recover from unexpected events. The two level design provides tolerance of two or more faults occurring serially at any level of command, control, sensing, or actuation. The potential benefits of such a fault tolerant robotic control system include: (1) a minimized potential for damage to humans, the work site, and the robot itself; (2) continuous operation with a minimum of uncommanded motion in the presence of failures; and (3) more reliable autonomous operation providing increased efficiency in the execution of robotic tasks and decreased demand on human operators for controlling and monitoring the robotic servicing routines

The introduction of an holistic design approach through a teaching company scheme

Traditional design approaches separate the various functions of design such as material selection, performance modelling and tolerance specification into discrete entities. Whilst this allows more focused methods to be used at each stage, areas of conflict or benefit may be overlooked, and the designer is left to bring the loose ends together. This paper looks at a synthesis approach that draws upon a number of current design themes. The design process is considered along with various aspects such as product development, design-for-`X' methodologies and material selection. The need for the preservation of design knowledge and reasoning, the so called wh-? questions, within the process are considered along with various models of the design process. The paper draws these various aspects together to form a more holistic approach to design. The application of this technique within the Teaching Company Scheme is briefly discussed

Applications of Soft Computing in Mobile and Wireless Communications

Soft computing is a synergistic combination of artificial intelligence methodologies to model and solve real world problems that are either impossible or too difficult to model mathematically. Furthermore, the use of conventional modeling techniques demands rigor, precision and certainty, which carry computational cost. On the other hand, soft computing utilizes computation, reasoning and inference to reduce computational cost by exploiting tolerance for imprecision, uncertainty, partial truth and approximation. In addition to computational cost savings, soft computing is an excellent platform for autonomic computing, owing to its roots in artificial intelligence. Wireless communication networks are associated with much uncertainty and imprecision due to a number of stochastic processes such as escalating number of access points, constantly changing propagation channels, sudden variations in network load and random mobility of users. This reality has fuelled numerous applications of soft computing techniques in mobile and wireless communications. This paper reviews various applications of the core soft computing methodologies in mobile and wireless communications

Tolerance, Mıgratıon And Hybrıd Identities: Normative Reasoning Of Intercultural Dialogue In A Blurring Structure

The aim of this study is to proof the argument – i.e. ‘there are significant linkages amongst tolerance, hybrid identities and migration.’ These linkages can be comprehended by means of conceptualising extensions of hybrid identities in aggregate trans/inter-migration processes. It can be put forward that arising hybrid identities are embedded in a blurring structure of thoughts, beliefs, states of affairs, facts, belongings and so forth. From multiculturalism and cosmopolitanism viewpoints, it is argued that tolerance and migration ought to be analysed in frame of sociology of law, human rights, international migration law, and of course the European Union law. So far, normative arguments and soft law approaches are very much well integrated with social aspects of migration, tolerance, identity and culture. In this context, the study examines to what extent cultural and human components are protected by law in multiple levels from an interdisciplinary perspective. In this framework, it is crucial to raise the research enquiries: What are possible criteria for the limits of tolerance? To what extent tolerance is related to human rights and morality? What ought to be the limit of tolerance towards hybrid identities in multicultural and cosmopolitan societies? In a consistent manner, the criteria and standards developed by some leading scholars were reconstructed and discussed throughout this paper. These criteria and standards are both moral (part of a universal system of morality) and legal (international, supranational, or national – i.e. constitutional). In order to apply such standards their validity was discussed (i.e. the respective normative power has the norms at the various levels). In the case of morals, their difference to particular ethnic systems was established (i.e. criteria by which the two can be distinguished). Then the research argument was elaborated on whether and how the legal standards comply with the moral standards, how national standards comply with supranational or international standards. Likewise, the study highlights the crucial contributions of “World Society and World System Paradigms” that are associated with social space, global civil society, cosmopolitanism, ethnic diversity, cultural hybridity, human rights activism and public sphere. Recent debates in Refugee Studies (e.g. Syrian Refugee Crisis, Dual and Multiple Citizenship Issues and so forth) highlight the fact that the European Union needs to consider new aspects of tolerance for hybrid identities and tolerate cultural rights of hybrid identities, create cohesion in communities and establish intercultural dialogue amongst home-states and host-states. Sanguinely, the efforts of hybrid identities are strengthening the relations between home-host states and these ought to attract some considerable attention. The authors of this study hope that their endeavours may contribute somewhat towards that
