A Model of Emotion as Patterned Metacontrol
Adaptive systems use feedback as a key strategy to cope with uncertainty and change in their environments. The information fed back from the sensorimotor loop into the control architecture can be used to change different elements of the controller at four different levels: parameters of the control model, the control model itself, the functional organization of the agent and the functional components of the agent. The complexity of such a space of potential conïŹgurations is daunting. The only viable alternative for the agent ?in practical, economical, evolutionary terms? is the reduction of the dimensionality of the conïŹguration space. This reduction is achieved both by functionalisation âor, to be more precise, by interface minimizationâ and by patterning, i.e. the selection among a predeïŹned set of organisational conïŹgurations. This last analysis let us state the central problem of how autonomy emerges from the integration of the cognitive, emotional and autonomic systems in strict functional terms: autonomy is achieved by the closure of functional dependency. In this paper we will show a general model of how the emotional biological systems operate following this theoretical analysis and how this model is also of applicability to a wide spectrum of artiïŹcial systems
The Unbearable Heaviness of Being in Phenomenologist AI
The aim of this paper is to pin down the misuse of Heideggerâs philosophal insights within the discipline of artificial intelligence (AI) and robotics. In this paper we argue that a central thesis of phenomenology, in Husserlâs words, âputting the world between bracketsâ, has led to a positioning in embodied AI that deeply neglects fundamental representational aspects that are totally necessary for the purpose of building a theory of cognition. The unification of representational and being-in-the-world aspects, are necesary for the explanation and realization of complex consciousness phenomenon in a cognizer, both animal and mechanic. The emphasis on the self (post-cognitivists), on the being (phenomenologists), as well as the Being by Heideggerâs followers, has contributed interesting insights concerning the puzzle of cognition and consciousness. However, has neglected the necessity and even denied the possibility to provide a scientific theory of cognition.
On the other hand, the phenomenologistâs separation of the world into two different ones, the scientific and objective world, and that of our common and lived experience is untenable. The claim that any scientific-theoretical world must find its foundation in the so called live world is ill-founded. In this paper we will propose the basis of a theoretical framework where only one world âwith entities and processesâ exists and can be known to a certain degree by the cognitive system. This calls for a unified vision of both ontology and epistemology
Consciousness, Meaning and the Future Phenomenology
Phenomenological states are generally considered sources of intrinsic motivation for autonomous biological agents. In this paper we will address the issue of exploiting these states for robust goal-directed systems. We will provide an analysis of consciousness in terms of a precise definition of how an agent âunderstandsâ the informational flows entering the agent. This model of consciousness and understanding is based in the analysis and evaluation of phenomenological states along potential trajectories in the phase space of the agents. This implies that a possible strategy to follow in order to build autonomous but useful systems is to embed them with the particular, ad-hoc phenomenology that captures the requirements that define the system usefulness from a requirements-strict engineering viewpoint
Towards architectural foundations for cognitive self-aware systems
In this talk we address a proposal concerning a methodology for extracting universal, domain neutral, architectural design patterns from the analysis of biological cognition. This will render a set of design principles and design patterns oriented towards the construction of better machines. Bio- inspiration cannot be a one step process if we we are going to to build robust, dependable autonomous agents; we must build solid theories first, departing from natural systems, and supporting our designs of artificial ones
Model-based Engineering of Autonomous Systems using Ontologies and Metamodels
Our research focuses on engineering processes for autonomous intelligent systems construction with a life-cycle holistic view, by means of a model-based framework. The conceptual core of the framework is ontologically-driven. Our ontological approach consists of two elements. The first one is a domain Ontology for Autonomous Systems (OASys) to capture the autonomous system structure, function and behaviour. The second element is an Ontology-driven Engineering Methodology (ODEM) to develop the target autonomous system. This methodology is based on Model-based Systems Engineering and produces models of the system as core assets. These models are used through the whole system life-cycle, from implementation or validation to operation and maintenance. On the application side, the ontological framework has been used to develop a metacontrol engineering technology for autonomous systems, the OM Engineering Process (OMEP), to improve their runtime adaptivity and resilience. OMEP has been applied to a mobile robot in the form of a metacontroller built on top of the robot's control architecture. It exploits a functional model of the robot (TOMASys Model) to reconfigure its control if required by the situation at runtime. The functional model is based on a metamodel about controller function and structure using concepts form the ontology. The metacontroller was developed using the ontology-driven methodology and a robot control reference architecture
A Model of Emotion as Patterned Metacontrol
Adaptive agents use feedback as a key strategy to cope with un- certainty and change in their environments. The information fed back from the sensorimotor loop into the control subsystem can be used to change four different elements of the controller: parameters associated to the control model, the control model itself, the functional organization of the agent and the functional realization of the agent. There are many change alternatives and hence the complexity of the agentâs space of potential configurations is daunting. The only viable alternative for space- and time-constrained agents âin practical, economical, evolutionary termsâ is to achieve a reduction of the dimensionality of this configuration space. Emotions play a critical role in this reduction. The reduction is achieved by func- tionalization, interface minimization and by patterning, i.e. by selection among a predefined set of organizational configurations. This analysis lets us state how autonomy emerges from the integration of cognitive, emotional and autonomic systems in strict functional terms: autonomy is achieved by the closure of functional dependency. Emotion-based morphofunctional systems are able to exhibit complex adaptation patterns at a reduced cognitive cost. In this article we show a general model of how emotion supports functional adaptation and how the emotional biological systems operate following this theoretical model. We will also show how this model is also of applicability to the construction of a wide spectrum of artificial systems1
Ontologies as Backbone of Cognitive Systems Engineering
Cognitive systems are starting to be deployed as appliances across the technological landscape of modern societies. The increasing availability of high performance computing platforms has opened an opportunity for statistics-based cognitive systems that perform quite as humans in certain tasks that resisted the symbolic methods of classic artificial intelligence. Cognitive artefacts appear every day in the media, raising a wave of mild fear concerning artificial intelligence and its impact on society. These systems, performance notwithstanding, are quite brittle and their reduced dependability limips their potential for massive deployment in mission-critical applications -e.g. in autonomous driving or medical diagnosis. In this paper we explore the actual possibility of building cognitive systems using engineering-grade methods that can assure the satisfaction of strict requirements for their operation. The final conclusion will be that, besides the potential improvement provided by a rigorous engineering process, we are still in need of a solid theory -possibly the main outcome of cognitive science- that could sustain such endeavour. In this sense, we propose the use of formal ontologies as backbones of cognitive systems engineering processes and workflows
A design process for harware/software system co-design and its application to designing a reconfigurable FPGA
This paper is going to address the topic of hardware/software systems co-design. The paper will develop two points of view. First, it provides a system-theoretical layout on the problem of designing hardware-software systems. This layout will enable the designer to proceed systematically in optimizing the tradeoff between the desired functionality, available resources and operating conditions. Second, the paper will describe an application of some of the theoretical principles to the design of an embedded automotive system built on a low-cost FPGA
Engineering an Ontology for Autonomous Systems - The OASys Ontology
This paper describes the development of an ontology for autonomous systems, as the initial stage of a research programe on autonomous systemsâ engineering within a model-based control approach. The ontology aims at providing a uniïŹed conceptual framework for the autonomous systemsâ stakeholders, from developers to software engineers. The modular ontology contains both generic and domain-speciïŹc concepts for autonomous systems description and engineering. The ontology serves as the basis in a methodology to obtain the autonomous systemâs conceptual models. The objective is to obtain and to use these models as main input for the autonomous systemâs model-based control system
Ontology driven description and engineering of autonomous systems: application to process system engineering
Autonomous systems refer to systems capable of operating in a real world environment without any form of external control for extended periods of time. Autonomy is a desired goal for every system as it improves its performance, safety and profit. Ontologies are a way to conceptualize the knowledge of a specific domain. In this paper an ontology for the description of autonomous systems as well as for its development (engineering) is presented and applied to a process. This ontology is intended to be applied and used to generate final applications following a model driven methodology
