What robots want? Hearing the inner voice of a robot.
2021
Summary The inner speech is thoroughly studied in humans, and it represents an interdisciplinary research issue involving psychology, neuroscience, and pedagogy. A few papers only, mostly theoretical, analyze the role of inner speech in robots. The present study investigates the potential of the robot's inner speech while cooperating with human partners. A cognitive architecture is designed and integrated with standard robot routines into a complex framework. Two threads of interaction are discussed by setting the robot operations with and without inner speech. Thanks to the robotic self-dialog, the partner can easily trace the robot's processes. Moreover, the robot can better solve conflic…
Cognitive Systems Research: Special Issue on Biologically Inspired Cognitive Architectures: Papers from the Tenth Annual International Conference on …
2021
This Special Issue of Cognitive System Research on Biologically Inspired Cognitive Architectures: Papers from the Tenth Annual International Conference on Biologically Inspired Cognitive Architectures (BICA 2019) have solicited and collected research papers in all domains of science and technology that directly or indirectly may help us to make an advance toward the BICA Challenge, which is to implement the top essential functionality of the human mind in a machine. The selected papers included here are based on presentations given from 16 to 18 August 2019 during the 10th Annual International Conference on Biologically Inspired Cognitive Architectures (BICA 2019) held at the Microsoft Main…
Exploiting the Human Factor in a WSN-Based System for Ambient Intelligence
2009
Practical applications of ambient intelligence cannot leave aside requirements about ubiquity, scalability, and transparency to the user. An enabling technology to comply with this goal is represented by wireless sensor networks (WSNs); however, although capable of limited in-network processing, they lack the computational power to act as a comprehensive intelligent system. By taking inspiration from the sensory processing model of complex biological organisms, we propose here a cognitive architecture able to perceive, decide upon, and control the environment of which the system is part. WSNs act as a transparent interface that allows the system to understand human requirements through impl…
Mimicking biological mechanisms for sensory information fusion
2013
Current Artificial Intelligence systems are bound to become increasingly interconnected to their surrounding environment in the view of the newly rising Ambient Intelligence (AmI) perspective. In this paper, we present a comprehensive AmI framework for performing fusion of raw data, perceived by sensors of different nature, in order to extract higher-level information according to a model structured so as to resemble the perceptual signal processing occurring in the human nervous system. Following the guidelines of the greater BICA challenge, we selected the specific task of user presence detection in a locality of the system as a representative application clarifying the potentialities of …
An Ontology-Based Autonomic System for Ambient Intelligence Scenarios
2014
Pervasive computing and Ambient Intelligence (AmI) demonstrate that computer systems which directly interact with users are characterized by increasing size and complexity, so that the human user will still not be able to adequately manage them for a long time to come. As a response to this trend, the Autonomic Computing paradigm aims to design and develop systems able to self-configure and self-manage. The research reported here is part of an AmI project that proposes a multi-tier cognitive architecture for aggregating sensory information at different levels of abstraction. In such an architecture, a central reasoning component is able to understand the environmental state and the user’s p…

Overall, the volume presents a pleasant overview with contributions from many countries depicting all major topics in BICA Challenge research. Personally, I am very pleased to have served as guest editor, and I am convinced that…
Application of EαNets to Feature Recognition of Articulation Manner in Knowledge-Based Automatic Speech Recognition
2006
Speech recognition has become common in many application domains. Incorporating acoustic-phonetic knowledge into Automatic Speech Recognition (ASR) systems design has been proven a viable approach to rise ASR accuracy. Manner of articulation attributes such as vowel, stop, fricative, approximant, nasal, and silence are examples of such knowledge. Neural networks have already been used successfully as detectors for manner of articulation attributes starting from representations of speech signal frames. In this paper, a set of six detectors for the above mentioned attributes is designed based on the E-αNet model of neural networks. This model was chosen for its capability to learn hidden acti…
On a Roadmap to Biologically Inspired Cognitive Agents
2011
A new challenge is proposed for future intelligent artifacts based on biologically inspired cognitive architectures (BICA), called the BICA Challenge. Namely, it is proposed that a BICA agent can only be considered human-level intelligent if it can be accepted and trusted as an equal member (a “person”) by a human community. For example, an agent of this sort would be able to win a political election against human candidates.
Experiences with CiceRobot, a Museum Guide Cognitive Robot
2005
The paper describes CiceRobot, a robot based on a cognitive architecture for robot vision and action. The aim of the architecture is to integrate visual perception and actions with knowledge representation, in order to let the robot to generate a deep inner understanding of its environment. The principled integration of perception, action and of symbolic knowledge is based on the introduction of an intermediate representation based on Gardenfors conceptual spaces. The architecture has been tested on a RWI B21 autonomous robot on tasks related with guided tours in the Archaeological Museum of Agrigento. Experimental results are presented.
Awareness Mechanisms for an Intelligent Tutoring System
2008
In this work an Intelligent Tutoring System (ITS) is presented that is able to enrich its knowledge base, merging both partially structured and unstructured information in a unique internal representation framework. The system gathers new information about the domain in response to both a curiosity mechanism and sensory stimuli coming from the interaction with the user. The architecture is an evolution of TutorJ, an actual ITS already presented by some of the authors. The cognitive framework is a very promising one to overcome the limitations of classical ITSs, and to achieve the stated goal. The use of cognitive architectures is intended for a double result: a lower effort for a knowledge-…
