MS05: Mathematics for Big Data

The talks in this minisymposium are addressing different mathematical challenges coming from Big Data problems, in broad sense - either in the sense of development of optimization and statistical methods for modelling and solving problems that arise in real life decision process, applications to modelling complex system and analysing their outputs.

The topics which will be covered in the minisymposium vary from optimization methods designed for machine learning problems, noisy optimization, adversarial attacks on neural networks, uncertainty quantification in deep learning, functional statistics and stochastic geometric models for face recognition and linear algebra methods for big data analysis.
Almost all topics are either coming from a specific industrial problem or are highly applicable in real life data analysis.
In particular, 6 talks are on industrial projects developed within H2020 MSC BIGMATH project (grant n. 812912).
