Computational Harmonic Analysis & Machine Learning
Our scientific interests focus on harmonic analysis, inverse problems, PDE and machine learning.
Research
From theory to practice: a multidisciplinary effort
MaLGa is primarily a center for fundamental research. A main feature of the research activity at MaLGa is the idea that a fruitful interplay between theoretical and applied questions is the key for long-lasting and impactful contributions. More broadly, this has always been the founding feature of ML studies at the University of Genoa. Our present and past research has always been equally split between foundational work in ML theory, and applied projects, working closely with partners such as hospitals or industries to develop vertical solutions.
Research units
Computational Imaging and Learning
We combine physical and mathematical modelling with advanced optimisation and learning techniques to solve inverse problems arising in biomedical imaging and beyond.
Machine Learning & Vision
We investigate different nuances of visual perception in artificial intelligence systems, where computer vision and machine learning are combined to obtain robust data-driven methods addressing a variety of problems.
Computational & statistical learning
Our aim is to advance the frontiers of learning theory and machine learning, while building algorithmic tools for the analysis of complex systems and high dimensional data.
Physics informed Machine Learning for biological Behavior
We blend physics with machine learning and biological behavior to ask how organisms strive in a fluid environment dominated by uncertainty.
