Lorenzo Andrea Rosasco 28 dicembre 2018 PERSONAL INFORMATION Citizenship: Italian and United States Contact addresses: Universita´ degli Studi di Genova, via Dodecaneso 35, Genova, Italy RESEARCH INTERESTS My main interest is machine learning. Learning is widely acknowledged to be key for understanding human and machine intelligence. A computational scheme able to acquire knowledge and decision ma- king skills cannot simply memorize data. Rather, it must be able to learn, that is to efficiently process and summarize the flood of available data coming from sensory systems. At its core, learning is an inference problem from complex, high dimensional, noisy data. I am interested into the principles that allow to learn from small as well as massive samples of data and into the computational schemes that implement these principles. I pursue these questions using probabilistic and analytical tools, within a multidisciplinary approach drawing concepts and techniques primarily from computer science but al- so from statistics, engineering and applied mathematics. Applications in computer vision and robotics motivate some of the computational learning schemes I study and provide a natural ground to test their properties. Keywords: Machine Learning, Optimization, Inverse problems and Regularization, High Dimensio- nal Statistics and Probability, Reproducing Kernel Hilbert Spaces.
