In this paper an extensive experimental evaluation of an evolutionary approach t o c o n-cept learning is presented. The experimentation , performed with the system G-NET, investigates the eeectiveness of the approach along the following dimensions: Robustness with respect to parameter setting, eeective-ness of the MDL criterion coupled with a stochastic(More)
This paper presents a highly parallel genetic algorithm , designed for concept induction in proposi-tional and first order logics. The system exploits niches and species for learning multimodal concepts ; it deeply differs from other systems because of the distributed architecture, which totally eliminates the concept of common memory. A first(More)
INTRODUCTION The culture-independent serum (1→3)-β-D-glucan (BG) detection test may allow early diagnosis of invasive fungal disease, but its clinical usefulness needs to be firmly established. A prospective single-center observational study was conducted to compare the diagnostic value of BG assay, Candida score (CS), and colonization index in intensive(More)
INTRODUCTION The high incidence of multidrug-resistant (MDR) bacteria among patients admitted to ICUs has determined an increase of tigecycline (TGC) use for the treatment of severe infections. Many concerns have been raised about the efficacy of this molecule and increased dosages have been proposed. Our purpose is to investigate TGC safety and efficacy at(More)
The automatic construction of classiiers (programs able to correctly classify data collected from the real world) is one of the major problems in pattern recognition and in a wide area related to Artiicial Intelligence, including Data Mining. In this paper we present G-Net, a distributed algorithm able to infer classiiers from pre-collected data, and its(More)
To avoid the complications associated with endotracheal intubation, noninvasive positive-pressure ventilation (NPPV) has been proposed in the management of ventilator weaning in patients with acute respiratory failure (ARF) of various etiologies. Several studies have been performed to assess the benefit of NPPV in various weaning strategies, including(More)
