About the Workshop

The "PRIMO Workshop" offers early-career researchers working on topics within the broad research areas of imaging science, machine learning/deep learning and non linear optimization a stage to share their work and network with peers and future collaborators.

This event is strictly related to the recently founded PRIMO (Post-graduate Researchers in Inverse problems, Machine learning, and Optimization) Research Group. The group, which started its activities in Summer 2020, currently counts more than 60 members from different Italian and international istitutions.

Every young researcher in these areas is strongly encouraged to register and submit an abstract for an in-person presentation. The registration is free of charge (but mandatory) and includes coffee breaks and lunches.

The 3th edition of the "PRIMO Workshop", as part of the PRIMO ResearchGroup activities, is a three-day event taking in place in Bari (Italy) and organized by MIδAS (Mathematics In Data AnalysiS) Research Group. The event will take place on September 20-22, 2023 at the Department of Mathematics at UniBa.

Organizing committee: Nicoletta Del Buono, Flavia Esposito, Grazia Gargano, Laura Selicato, Gaetano Settembre.

Journal: Journal of Computational Mathematics and Data Science (ISSN: 2772-4158)
Special issue: Learning from data: from Optimization to Inverse problems

Description: Over the past decade, machine learning has emerged as a major driving force in the growth of innovation. With the increasing amount of data generated, the research community in this field has expanded rapidly and achieved significant progress in processing and analyzing data. This development has enabled the creation of interpretative models for learning from data that are precise and reliable as well as more effective. The rapid development of learning approaches naturally flows in the requirement for a mathematical formalization and computational analysis of the related issues. These cover several fields of mathematics, from optimization to inverse problems, encountering several open questions in many real applications. Regarding learning approaches, the special issue aims to examine the most recent developments in mathematical and computational techniques for practical applications. It also examines the most recent and cutting-edge algorithms for finding patterns, relationships, and correlations in sizable real-world datasets. The articles in this special issue will then get straight to the main problems with data preprocessing, analysis, and interpretation.

Interest-related subjects include, but are not limited to:

  • Optimization in machine learning algorithms;
  • Inverse problems;
  • Parameter and Hyperparameter estimation;
  • Low-rank methods for data analysis;
  • Image reconstruction;
  • Image processing;
  • Regularization and penalization methods and their applications;
  • Algorithms for feature extraction and selection from real data.
