Talks and Posters

The best oral presentation and the poster will receive an award, sponsored by GIRPR "Gruppo Italiano Ricercatori in Pattern Recognition", which consists of a cash price of 250 euro. The award will be conferred at the end of the School.
The name of the winners will be published in the GIRPR Newsletter and on this webpage.

Oral presentation.

Each speaking slot is 25 minutes long. Your presentation should last 20 minutes, leaving time for questions and transitions between speakers. Speakers will receive a detailed schedule in the next few days. Once you have been assigned to a session, please meet the organizers before your session begins. This will give you time to test your laptop and slides. It will also give you a chance to tell them who will be giving the talk and to help them pronounce your name correctly.

Confirmed Speakers:

Pilarczyk Pawel - Inducing a map on homology from a correspondence
Mondejar Diego - Cech homology from finite approximations
Belchi Guillamon Francisco - Persistence and links

Poster Session

The poster session will be held on Wednesday, Feb. 11, 2015 between 16:30-20:00.

The size of your poster should be A1 (no more than 30 inches wide and 48 inches tall). We will provide you with a backing board of this size along with binder clips to hold the posters to it. Please do not make a poster larger than the recommended size. In order to help you interact with the people who view your  poster, you should prepare a short oral presentation of about 2 or 5 minutes .

Below, we provide some information that will help you with the preparation of the poster.

Confirmed Posters:

Centin Marco - Delaunay Meshing of Poisson Reconstructions
Deniz Zakir - Homotopy Type of Acyclic Complexes of Tournaments and Some Applications
Di Fabio Barbara - Comparing persistence diagrams through complex vectors
Hashemi Eliza - Efficiency of Combined Concurrence Homology and Laplacian Graph Applied in Microarray Data
Patania Alice - Homological Methods for Temporal Networks
Sarmiento Camilo - On algebraic Betti numbers of clique complexes of large graphs
Schubel Mark - Eigenvalues of the 1-Laplacian

The title of your poster should appear at the top in CAPITAL letters about 25mm high. Below the title put the author(s)' name(s) and affiliation(s). The flow of your poster should be from the top left to the bottom right. Use arrows to lead your viewer through the poster. Use color for highlighting and to make your poster more attractive. Use pictures, diagrams, cartoons, figures, etc., rather than text wherever possible. Try to state your main result in 6 lines or less, in lettering about 15mm high so that people can read the poster from a distance. The smallest text on your poster should be at least 9mm high, and the important points should be in a larger size. Use a sans-serif font (such as "cmss" in the Computer Modern family or the "Helvetica" PostScript font) to make the print easier to read from a distance. Make your poster as self-explanatory as possible. This will save your efforts for technical discussions. You may bring additional audio or visual aids to enhance your presentation.


Title: Effective homology: perturbation lemma and applications
Lecturer: Julio Rubio - University of La Rioja
Abstract:  In the talk we will review the main algorithmic techniques underlying the Kenzo computer algebra system, with an emphasis in the interplay between effective homology and perturbation methods. At the end of the talk we will present some recent applications to the homology of groups and to the processing of biomedical images.
Title: Persistent homology for complex network analysis
Lecturer: Francesco Vaccarino - Politecnico di Torino
Abstract: We will introduce our recent results on the use of persistent homology in the field of complex networks. In particular we will show that, by filtering on weighted graph, persistence is capable to discriminate various kind of networks with an application to the analysis of the variation of the brain functional connectome under the influence of psychedelic drugs. We, furthermore give account of our theorem which shows that a persistence module on a finite poset P can be obtained from the filtration of a graph weighted over P.

Generalized persistent homologies: G-invariant and multi-dimensional persistence





NEW   -   Papers: G-Invariant Persistence

NEW - Slides: Introduction and Motivation, G-Invariant Persistence, Multi-Dimensional Persistence

NEW  -  Exercises: Basic Persistence, G-Invariant PersistenceMulti-Dimensional Persistence


Persistent homology is currently a very popular tool for topological analysis of data in diverse disciplines. In its classical formulation, it yields invariants of scalar fields with respect to the action of a very broad set of transformations on the field's domain, that is the set of all self-homeomorphisms. This  may restrict its use in applications, where vector fields  occur  more often than scalar fields, and the invariance group of interest is usually a more restricted group G. In this course two generalizations of persistent homology, the G-invariant persistence and the multi-dimensional persistence, are presented to overcome the aforementioned shortcomings of classical persistence. In particular, the focus will be on the associated invariants and their applications in shape comparison. 

Lecturer: Massimo Ferri

Massimo Ferri is the founder of the group of Visione Matematica born in the 90's with the aim of explore possible application of the geometry and of the topology in robotics and in pattern recognition.The group has been pioneer in the 0-dimensional persistent homology introducing the theory of the size functions. The group works in the network “Appliedand Computational Algebraic Topology (ACAT)”, supported by the European Science Foundation,which has the aim of encourage the creation of a research community integrated on topics of computational topology.
