Multidisciplinary Perspectives on Artificial Intelligence and the Law
Antunes, Henrique Sousa; Freitas, Pedro Miguel; Oliveira, Arlindo; Pereira, Clara Martins; Sequeira, Elsa Vaz de; Xavier, Luís BarretoThis book is the outcome of a collaborative effort. Five years ago, research group “Law and Artificial Intelligence”—hosted by the Católica Research Centre for the Future of Law (Universidade Católica Portuguesa—UCP, Lisbon, Portugal) and led by Henrique Sousa Antunes (UCP) and Arlindo Oliveira (Instituto Superior Técnico—IST)—started an ongoing scientific dialogue among scholars with diverse backgrounds and in...
Multidimensional Polynomial Powers of Sigmoid (PPS) wavelet neural networks
Marar, João Fernando [UNESP]; Coelho, HelderMade available in DSpace on 2022-04-28T20:45:05Z (GMT). No. of bitstreams: 0 Previous issue date: 2008-11-13; Wavelet functions have been used as the activation function in feedforward neural networks. An abundance of R&D has been produced on wavelet neural network area. Some successful algorithms and applications in wavelet neural network have been developed and reported in the literature. However, most of the...

Marar, João Fernando [UNESP]; Coelho, HelderMade available in DSpace on 2022-04-28T20:47:25Z (GMT). No. of bitstreams: 0 Previous issue date: 2008-12-17; In this paper, we described how a multidimensional wavelet neural networks based on Polynomial Powers of Sigmoid (PPS) can be constructed, trained and applied in image processing tasks. In this sense, a novel and uniform framework for face verification is presented. The framework is based on a family of...
Bringing underused learning objects to the light: a multi-agent based approach
Behr, André; Cscalho, José; Mendes, Armando B.; Guerra, Hélia; Cavique, Luís; Trigo, Paulo; Coelho, Helder; Vicari, RosaThe digital learning transformation brings the extension of the traditional libraries to online repositories. Learning object repositories are employed to deliver several functionalities related to the learning object’s lifecycle. However, these educational resources usually are not described effectively, lacking, for example, educational metadata and learning goals. Then, metadata incompleteness limits the qua...
Molecular Staging of Patients with Colon Cancer. The C-Closer-II Study: A Multi...
Brito, María José; Honavar, Mrinalini; Cipriano, Maria Augusta; Lopes, Joanne; Coelho, Helder; Silva, António Rodrigues da; Silva, MárioIntroduction: Approximately 20% - 30% of histological lymph node-negative patients with colorectal cancer relapse at five years after surgical treatment. This recurrence is likely due to occult nodal disease undetected by standard histopathological practice which has implications in terms of the clinical management of patients.Material and Methods: Lymph nodes were collected from colectomy specimens. A central ...
Electricity markets with increasing levels of renewable generation: structure, ...
Lopes, Fernando; Coelho, HelderABSTRACT: This book describes the common ground between electricity markets (EMs) and software agents (or artificial intelligence generally). It presents an up-to-date introduction to EMs and intelligent agents, and offers a comprehensive description of the research advances and key achievements related to existing and emerging market designs to reliably and efficiently manage the potential challenges of variab...
Agent-based computational modelling: Facing complexity
Coelho, HelderThe analysis of social and dynamical systems faces a paradigm shift, from mathematical methods to agent-based simulation. It is a new line of thinking, multidisciplinary, where technological and conceptual innovations grow, and where artificial societies of individual and intelligent agents are generated to replicate simple and plausible human beings. This paper deals with agent models and the ways how simple r...
Exploratory Apprenticeship in the Digital Age with AI Tools
Coelho, Helder; Thompsen Primo, TiagoAlong this decade, advances from Cognitive and Computing Sciences disturbed the college campus, namely via the availability of online courses (MOOCs) and tools, and also the secondary schools with e-learning environments. The technological impacts helped to democratize traditional university education and brought, to everywhere in the world, the teaching of wonderful professors through Internet (YouTube). Yet, ...
