On Avoiding Redundancy in Inductive LogicProgramming
- Nuno A Fonseca; Vítor Santos Costa; Fernado Silva; Rui Camacho
ILP systems induce rst-order clausal theories performing asearch through very large hypotheses spaces containing redundant hypotheses.The generation of redundant hypotheses may prevent the systemsfrom nding good models and increases the time to induce them.In this paper we propose a classication of hypotheses redundancy andshow how expert knowledge can be provided to an ILP system to avoidit. Experimental results show that the number of hypotheses generatedand execution time are reduced when expert knowledge is used to avoidredundancy.

Flexibilidade do Design de Produto como Resposta à Variação das Condicionantes Tecnológicas de Fabrico
- Carlos Aguiar; Carla Rocha; Fernando Gomes Almeida; Nuno Couto
Neste trabalho pretende-se abordar a importância dos conceitos formais propostos pelo Design serem capazes de se adaptar e potenciar a competitividade das soluções impostas pelas condicionantes técnicas (materiais e processos de fabrico) num projecto de desenvolvimento de produto, permitindo, assim, encontrar a melhor solução em termos de custos de produção e adequada resposta às necessidades dos utilizadores. O caso agora apresentado refere-se ao design de diferentes conceitos para uma carroçaria em material compósito de um autocarro que circulará em serviço de shuttle no Pólo Universitário da Asprela (Porto), no âmbito do projecto europeu CIVITAS.
From sequential to Parallel Inductive LogicProgramming
- Rui Camacho
Inductive Logic Programming (ILP) has achieved considerablesuccess in a wide range of domains. It is recognized however thateciency is a major obstacle to the use of ILP systems in applicationsrequiring large amounts of data. In this paper we address the problem ofeciency in ILP in three steps: i) we survey speedup techniques proposedfor sequential execution of ILP systems; ii) we survey dierent ways ofparallelizing an ILP system and; ii) adapt and combine the sequentialexecution speedup techniques in the parallel implementations of an ILPsystem. We also propose a novel technique to partition the search spaceinto independent sub-spaces that may be adequately...
HOPS - Hamming-Oriented Partition Search for production planning in the spinning industry
- Victor Camargo; Franklina Toledo; Bernardo Almada Lobo
In this paper, we investigate a two-stage lot-sizing and scheduling problem in a spinning industry.A new hybrid method called HOPS (Hamming-Oriented Partition Search), which is a branch-and-bound based procedure that incorporates a fix-and-optimize improvement method is proposedto solve the problem. An innovative partition choice for the fix-and-optimize is developed. The computational tests with generated instances based on real data show that HOPS is a goodalternative for solving mixed integer problems with recognized partitions such as the lot-sizing and scheduling problem.

A commodity platform for Distributed Data Mining -- the HARVARD System
- Ruy Ramos; Rui Camacho; Pedro Ferreira Do Souto
Systems performing Data Mining analysis are usually dedicated and expensive. They often require special purpose machines to run the data analysis tool. In this paper we propose an architecture for distributed Data Mining running on general purpose desktop computers. The proposed architecture was deployed in the HARVesting Architecture of idle machines foR Data mining (HARVARD) system.The Harvard system has the following features. Does not require specialpurpose or expensive machines as it runs in general purpose PCs. It isbased on distributed computing using a set of PCs connected in a network. In a Condor fashion it takes advantage of a distributed...
Dynamic simulation of human motion
- nunes, jf; reis, lp; rossetti, rjf; moreira, pm; tavares, jmrs
In order to study the mechanisms behind the human motion and its disorders, and to comprehend how do neuromuscular impairments affect the human movements, it is crucial to know the human musculoskeletal system. This knowledge is also essential to effectively model and analyse the musculoskeletal system, and to classify the human movement. With this work we conducted preliminary studies over a musculoskeletal model in motion, and performed a comparative analysis in gait between two models: one with a non-pathological gait and another with a disordered gait.
Robust and real-time motion capture of rigid bodies based on stereoscopic vision
- António Paulo Moreira; Paulo Gomes Da Costa; Fernando Veloso Gomes; Francisco Taveira Pinto; Paulo Lima Malheiros; Paulo Jorge Rosa-Santos
This paper presents a stereoscopic vision system developed to measure the motion of rigid bodies in real-time along its six degrees of freedom (6DOF). The idea was to use it in the measurement of the motions of a full-scale oil tanker moored at the oil terminal of the Port of Leixões, Portugal, in the scope of an RD project. Prior to its installation on site the system was tested and validated in laboratory. For that, use was made of ongoing physical modeltests of the behaviour of a moored oil tanker (scale 1/100). To analyse its accuracy the results obtained with...
