Texte intégralRecent advances in several research fields of Life Sciences, such as Bioinformatics, Computational Biology and Medical Imaging, are generating huge amounts of data that require effective computational tools to be analyzed, while other disciplines, like Systems Biology, typically deal with mathematical models of biochemical networks, where issues related to the lack of quantitative parameters and the efficient description of the emergent dynamics must be faced. In these contexts, High-Performance Computing (HPC) infrastructures represent a fundamental means to tackle these problems, allowing for both real-time processing of data and fast simulations. In the latest years, the use of general-purpose many-core devices, such as Many Integrated Core coprocessors and Graphics Processing Units (GPUs), gained ground. The second ones, which are pervasive, relatively cheap and extremely efficient parallel many-core coprocessors capable of achieving tera-scale performance on common workstations, have been extensively exploited in the work presented in this thesis. Moreover, some of the problems described here require the application of Computational Intelligence (CI) methods. As a matter fact, the Parameter Estimation problem in Systems Biology, the Haplotype Assembly problem in Genome Analysis as well as the enhancement and segmentation of medical images characterized by a bimodal gray level intensity histogram can be viewed as optimization problems, which can be effectively addressed by relying on CI approaches. In the case of the Parameter Estimation problem, Evolutionary and Swarm Intelligence techniques were exploited and coupled with novel GPU-powered simulators-designed and developed in this thesis to execute both coarse-grained and fine-grained simulations-which were used to perform in a parallel fashion the biochemical simulations underlying the fitness functions required by these population-based approaches. The Haplotype Assembly and the enhancement of medical images problems were both addressed by means of Genetic Algorithms (GAs), which were shown to be very effective in solving combinatorial problems. Since the proposed approaches based on GAs are computationally demanding, a Master-Slave paradigm was exploited to distribute the workload, reducing the required running time. The overall results show that coupling HPC and CI techniques is advantageous to address these problems and speed up the computational analyses in these research fields.

Texte intégralNowadays, the amount of heterogeneous biomedical data is increasing more and more thanks to novel sensing techniques and high-throughput technologies. In reference to biomedical image analysis, the advances in image acquisition modalities and high-throughput imaging experiments are creating new challenges. This huge information ensemble could overwhelm the analytic capabilities needed by physicians in their daily decision-making tasks as well as by biologists investigating complex biochemical systems. In particular, quantitative imaging methods convey scientifically and clinically relevant information in prediction, prognosis or treatment response assessment, by also considering radiomics approaches. Therefore, the computational analysis of medical and biological images plays a key role in radiology and laboratory applications. In this regard, frameworks based on advanced Machine Learning and Computational Intelligence can significantly improve traditional Image Processing and Pattern Recognition approaches. However, conventional Artificial Intelligence techniques must be tailored to address the unique challenges concerning biomedical imaging data. This thesis aims at proposing novel and advanced computer-assisted methods for biomedical image analysis, also as an instrument in the development of Clinical Decision Support Systems, by always keeping in mind the clinical feasibility of the developed solutions. The devised classical Image Processing algorithms, with particular interest to region-based and morphological approaches in biomedical image segmentation, are first described. Afterwards, Pattern Recognition techniques are introduced, applying unsupervised fuzzy clustering and graph-based models (i.e., Random Walker and Cellular Automata) to multispectral and multimodal medical imaging data processing. Taking into account Computational Intelligence, an evolutionary framework based on Genetic Algorithms for medical image enhancement and segmentation is presented. Moreover, multimodal image co-registration using Particle Swarm Optimization is discussed. Finally, Deep Neural Networks are investigated: (i) the generalization abilities of Convolutional Neural Networks in medical image segmentation for multi-institutional datasets are addressed by conceiving an architecture that integrates adaptive feature recalibration blocks, and (ii) the generation of realistic medical images based on Generative Adversarial Networks is applied to data augmentation purposes. In conclusion, the ultimate goal of these research studies is to gain clinically and biologically useful insights that can guide differential diagnosis and therapies, leading towards biomedical data integration for personalized medicine. As a matter of fact, the proposed computer-assisted bioimage analysis methods can be beneficial for the definition of imaging biomarkers, as well as for quantitative medicine and biology.
