Imitation Learning and Anchoring through Conceptual Spaces
2007
In order to have a robotic system able to effectively learn by imitation and not merely reproduce the movements of a human teacher, the system should have the capability to deeply understand the perceived actions to be imitated. This paper deals with the development of a cognitive architecture for learning by imitation in which a rich conceptual representation of the observed actions is built. The purpose of the following discussion is to show how the same conceptual representation can be used both in a bottom-up approach, in order to learn sequences of actions by imitation learning paradigm, and in a top-down approach, in order to anchor the symbolical representations to the perceptual act…
A cognitive architecture for music perception exploiting conceptual spaces
2015
A cognitive architecture for a musical agent is presented. The architecture extends and complete 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.
Cloning and training collective intelligence with generative adversarial networks
2021
Industry 4.0 and highly automated critical infrastructure can be seen as cyber‐physical‐social systems controlled by the Collective Intelligence. Such systems are essential for the functioning of the society and economy. On one hand, they have flexible infrastructure of heterogeneous systems and assets. On the other hand, they are social systems, which include collaborating humans and artificial decision makers. Such (human plus machine) resources must be pre‐trained to perform their mission with high efficiency. Both human and machine learning approaches must be bridged to enable such training. The importance of these systems requires the anticipation of the potential and previously unknow…
Knowledge representation for robotic vision based on conceptual spaces and attentive mechanisms
1995
A new cognitive architecture for artificial vision is proposed. The architecture is aimed for an autonomous intelligent system, as several cognitive hypotheses have been postulated as guidelines for its design. The design is based on a conceptual representation level between the subsymbolic level processing the sensory data, and the linguistic level describing scenes by means of a high-level language. The architecture is also based on the active role of a focus of attention mechanism in the link between the conceptual and the linguistic level. The link between the conceptual level and the linguistic level is modelled as a time-delay attractor neural network.
How to engineer biologically inspired cognitive architectures
2013
Biologically inspired cognitive architectures are complex systems where different modules of cognition interact in order to reach the global goals of the system in a changing environment. Engineering and modeling this kind of systems is a hard task due to the lack of techniques for developing and implementing features like learning, knowledge, experience, memory, adaptivity in an inter-modular fashion. We propose a new concept of intelligent agent as abstraction for developing biologically cognitive architectures. © 2013 Springer-Verlag.
New Technology, Writing And Learning
2001
The participants involved in most previous studies on writing have written their texts by hand but writing with the aid of a computer is much more prevalent today. This chapter specifically examines the effects of new technology on writing and, by implication, on writing to learn, and presents examples how technology has created new possibilities for using writing for purposes of learning. The chapter is divided into four main parts. Part one briefly introduces the chapter. Part two considers the nature of writing in terms of interactions between planning, writing and editing. Part three examines how computer aided writing changes these processes. Here individual and collaborative writing a…
Architectural Representation: a Tool for Urban Regeneration : the Colour Plan of Egadi Islands
2018
The Egadi Islands, at the western end of Sicily, preserve a peculiar architectural and environmental heritage. The work of people – related to tuna fishing, stone extraction and agriculture – has created, over time, an exceptional landscape. The nature, colour and texture of the local stone have given shape to a traditional architecture that, today, risks to disappear and to be replaced by new anonymous buildings. Furthermore, the pressure of tourism threatens to damage this delicate balance established, over centuries, between people and environment. Therefore, the Local Administration decided to adopt a Colour Plan to manage the inevitable processes of territorial transformations. The Arc…
On Brauer’s Height Zero Conjecture
2014
In this paper, the unproven half of Richard Brauer’s Height Zero Conjecture is reduced to a question on simple groups.
Circuit Lower Bounds via Ehrenfeucht-Fraisse Games
2006
In this paper we prove that the class of functions expressible by first order formulas with only two variables coincides with the class of functions computable by AC/sup 0/ circuits with a linear number of gates. We then investigate the feasibility of using Ehrenfeucht-Fraisse games to prove lower bounds for that class of circuits, as well as for general AC/sup 0/ circuits.
A code to evaluate prolate and oblate spheroidal harmonics
1998
Abstract We present a code to evaluate prolate ( P n m ( x ), Q n m ( x ); n ≥ m , x > 1) and oblate ( P n m ( ix ), Q n m ( ix ); n ≥ m , x > 0) spheroidal harmonics, that is, spherical harmonics ( n and m integers) for real arguments larger than one and for purely imaginary arguments. We start from the known values (in closed form) of P m m and P m +1 m and we apply the forward recurrence relation over n up to a given degree n = N Max . The Wronskian relating P 's and Q 's, together with the evaluation of the continued fraction for Q m+N staggeredMax m / Q m+N staggeredMax -1 m , allows the calculation of Q m+N staggeredMax m and Q m+N staggeredMax -1 m . Backward recurrence is then appli…
