Kernel Methods and Gaussian Processes for System Identification and Control: A Road Map on Regularized Kernel-Based Learning for Control
No full textThe commonly adopted route to control a dynamic system and make it follow the desired behavior consists of two steps. First, a model of the system is learned from input-output data, a task known as system identification in the engineering literature. Here, an important point is not only to derive a nominal model of the plant but also confidence bounds around it. The information coming from the first step is then exploited to design a controller that should guarantee a certain performance also under the uncertainty affecting the model. This classical way to control dynamic systems has recently been the subject of new intense research, thanks to an interesting cross-fertilization with the field of machine learning. New system identification and control techniques have been developed with links to function estimation and mathematical foundations in reproducing kernel Hilbert spaces (RKHSs) and Gaussian processes (GPs). This has become known as the Gaussian regression (kernel-based) approach to system identification and control. It is the purpose of this article to give an overview of this development (see 'Summary')

Return on NFTs
No full textCurrently, the best known applications of blockchain technology are finance and art. In particular, the blockchain art market, born in early 2018 without fuss, went parabolic around 2021, also thanks to record-breaking sales of digital artworks associated with a Non-Fungible Token (NFT), mediated by the grand dames of auction houses Christie’s and Sotheby’s. In this contribution we merge art and finance on blockchain and explore the opportunity of buying blockchain art as a financial investment. While there exists a relatively large literature on traditional art as investment, the topic of investing in NFTs is still in its infancy. Thus, we provide methods (metrics) and tools (a Web app) to reason about opportunities, in terms of risks and returns, of investing in art on chain
Adult laryngeal hemangioma CO2 laser excision. A single institution 3-year experience (Vittorio Veneto 2001-2003).
No full textCONCLUSIONS:
Adult supraglottic hemangiomas can be treated successfully with CO2 laser excision with limited morbidity. Extended laryngeal cavernous hemangiomas involving hypopharynx should be approached with staged CO2 laser surgical procedures.
OBJECTIVES:
Hemangioma of the adult larynx is an uncommon, benign lesion characterized by thin, friable mucosa overlying the vascular stroma. The optimal surgical approach to these lesions is still controversial because only anecdotal case reports or very limited series are available. We report a 3-year, retrospective, single institution study of the results of CO2 laser treatment of supraglottic hemangiomas in adults.
PATIENTS AND METHODS:
Six consecutive cases of adult laryngeal hemangioma were treated by the first author with CO2 laser microsurgery alone.
RESULTS:
In five of six cases, no recurrences have been diagnosed (median follow-up period: 29 months). One case presented limited persistence of disease in the retro-cricoid and arytenoids at 20-month follow-up control
