Software Design of an AGI System Based on Perception Loop
Get PDFAccording to the externalist approach, subjective experience hypothesizes a processual unity between the activity in the brain and the perceived event in the external world. A perception loop therefore occurs among the brain’s activities and the external world. In our work the metaphor of test is employed to create a software design methodology for implementing an AGI system endowed with the perception loop. Preliminary experiments with a NAO humanoid robots are reported
Towards the Adoption of a Perception-Driven Perspective in the Design of Complex Robotic Systems
Get PDFAwareness and autonomous interaction with the environment in a robotic system is the base of the new discipline of machine consciousness.
In this paper we present the results of a first attempt in order to engineer these robotic systems by applying a Situational Method Engineering approach that extends PASSI and to create a model for conscious systems
A cognitive architecture for music perception exploiting conceptual spaces
No full textA cognitive architecture for a musical agent is presented. The architecture extends an architecture for computer vision previously developed by the author by taking into account many relationships between vision and music perception. The focus of the agent architecture is an intermediate conceptual area between the subconceptual and linguistic areas. A conceptual space for the perception of tones and intervals is thus presented, based on the dissonance measure of the tones. Problems and future works of the proposed approach are finally discussed

Introducing the BICA Society
No full textThe Biologically Inspired Cognitive Architectures Society, or the BICA Society, is a recently formed nonprofit organization. The purpose of the Society is to promote and facilitate the transdisciplinary study of biologically inspired cognitive architectures (BICA), in particular, aiming at the emergence of a unifying, generally accepted framework for the design, characterization and implementation of human-level cognitive architectures. The First International Conference on Biologically Inspired Cognitive Architectures (BICA 2010) is at the same time officially the First Annual Meeting of the BICA Society
Habitats of the Chella Bank, Eastern Alboran Sea (Western Mediterranean)
No full text10 pages, 5 figuresThis chapter provides the first characterization of the geomorphic features and benthic habitats of the Chella Bank, a flat-topped volcanic peak situated in the Eastern Alboran Sea, Western Mediterranean. The Chella Bank, also named “Seco de los Olivos,” occurs along the upper slope of the Almeria Margin, showing a subcircular shape and covering a surface area of 100 km2 within a depth range of 70–700 m. High-resolution swath bathymetric mapping reveals three main large-scale morphological features on Chella Bank: the flat subhorizontal top and two main ridges, located to the west and to the east of the bank-top. Video tracks acquired in the area showed the occurrence of macrobenthic communities such as gorgonian assemblages (Callogorgia verticillata, Viminella flagellum), small patches of living cold-water corals (Madrepora oculata), and sponges (Fakelia ventilabrum). An automatic classification of multibeam data has been tested on the area as a predictive habitat mapping method, using backscatter characteristics (intensity, texture), and depth measurements as surrogate descriptors of the habitats recognized on the Chella Bank. The Chella Bank is one of the study areas of the LIFE-INDEMARES Project, which aims to contribute to the protection and sustainable use of the marine biodiversity in the Spanish seasWe acknowledge the Spanish National Projects EVENT (CGL2006-12861-C02-02) and SHAKE (CGL2011-30005-C02-02) of the Spanish Ministry of Science and Innovation (MICINN), the Acción Complementaria EVENT-SHELF (CTM2008-03346-E) of the MICINN, and the Grup de Recerca de la Generalitat de Catalunya B-CSI (2009 SGR 146)Peer Reviewe
Learning Problem Solving Skills from Demonstration: An Architectural Approach
Get PDFWe present an architectural approach to learning problem solving skills from demonstration, using internal models to represent problem-solving operational knowledge. Internal forward and inverse models are initially learned through active interaction with the environment, and then enhanced and finessed by observing expert teachers. While a single internal model is capable of solving a single goal-oriented task, it is their sequence that enables the system to hierarchically solve more complex task. Activation of models is goal-driven, and internal ”mental” simulations are used to predict and anticipate future rewards and perils and to make decisions accordingly. In this approach intelligent system behavior emerges as a coordinated activity of internal models over time governed by sound architectural principles. In this paper we report preliminary results using the game of Sokoban, where the aim is to learn goal-oriented patterns of model activations capable of solving the problem in various contexts
