Title:
Topology driven methods for complex systems modeling, an alternative approach to machine
learning. Theory and some examples.
Abstract:
Many complex systems are characterized by multi-level properties that make the study of
their dynamics and of their emerging phenomena a
daunting task. The huge amount of data available in modern sciences can be expected to
support great progress in these studies, even
though the nature of the data varies. Given that, it is crucial to extract as much as
possible features from data, including qualitative
(topological) ones. The goal of TOPDRIM project has been to provide methods driven by the
topology of data for describing the dynamics of
multi-level complex systems. To this end, the project has developed new mathematical and
computational formalisms accounting for
topological effects. To pursue these objectives, the project brought together scientists
from many diverse fields including as topology and
geometry, statistical physics and information theory, computer science and biology. The
proposed methods, obtained through concerted efforts,
covered different aspects of the science of complexity ranging from foundations, to
simulations through modelling and analysis, and
constituted the building blocks for a new generalized theory of complexity.
This seminar introduces the fundamentals behind the topological data analysis and through
some applications developed both in the
biomedical and financial field, presents the TOPDRIM methodology for going beyond the
concept of networks by considering simplicial
complexes instead.

Prof. Andrea Danani (IDSIA)
Short bios of the speakers:
Emanuela Merelli is a full professor of Computer Science at the University of Camerino.
She founded the BioShape & Big Data laboratory
conceived for young researchers with multidisciplinary interests in developing formal and
computational methods to understand the complex
behaviour of biological systems. She has been the coordinator of the TOPDRIM FP7-FET
project and the partner of LITBIO (Laboratory for
Interdisciplinary Technologies in Bioinformatics) Italian FIRB project. Currently, she is
collaborating with Mario Rasetti for
launching a new program on topological field theory of data with the aim to pave the way
for automata synthesis as recognizers of data
languages hidden in a given topological data space. Emanuela published many papers in
refereed international journals and is continuously
involved in the organization of events with an interdisciplinary character.
Marco Piangerelli is a biomedical engineer, received his doctorate in Computer Science at
the University of Camerino, under the supervision
of Prof. Emanuela Merelli. He is currently a post-doc and contract professor at the same
university where he deals with machine learning
and topological data analysis.
