Introduction to Copyright in ICT

By Brisa Burriel Fusterr, UPF. 

Abstract

We'll share the most relevant concepts of Copyright Law, and learn from popular cases, so we can have an idea of what is important to consider in our day to day.

Biography

I work as R&D and IT Legal Adviser at the UPF with a strong focus on Technology Transfer from the Public to the Private sector. My aim is to help organizations reaching the highest standards of valorization and exploitation of research results through IPRs awareness activities, as well as designing and implementing effective processes and best practices.

Fusion of images

By Enric Meinhardt-Llopis, École Normale Supérieure de Paris-Saclay

Abstract

The problem of image fusion consists in producing an ideal image of an object from several images of the object that are incomplete, deformed, blurry, noisy and with strong illumination changes.  This general problem contains as particular cases the problems of image registration, denoising, deblurring and inpainting.  We showcase three applications (1) the virtual periscope, that allows to see through the surface of turbulent water; (2) museum photography, to obtain clean and complete images of artwork from several incomplete and slanted photos; (3) reconstruction of asteroid surfaces, to combine inconsistent 3D models of an asteroid obtained from parallax and from shape-from-shading into a single coherent surface.  The fusion of N images always becomes a trivial problem in the limit when N goes to infinity; however in practice we are interested in the limit when N goes to 1.  We will see that, under rather mild hypotheses, the fusion of a small number of images is still a well-posed problem. 

Biography

Enric Meinhardt-Llopis is an associate professor at the École Normale Supérieure de Paris-Saclay.  After completing his studies in mathematics at the Universitat Politècnica de Catalunya, he obtained his PhD degree from the Universitat Pompeu Fabra in 2011, under the direction of Professor Vicent Caselles.  Now he is working in the image processing group of Professor Jean-Michel Morel, mostly in the analysis and exploitation of optical and radar satellite images.

Introduction to computational musicology with hands-on case studies for non-western music traditions

By Barış Bozkurt , Assoc. Prof. of Electrical Engineering at Izmir Democracy University, Turkey.

Abstract

The main goal of this tutorial is to present an overview for computational analysis applied on non-Western music traditions, mostly within the context of the CompMusic project (https://compmusic.upf.edu/). The target audience is researchers and students interested in computational musicology. The tutorial will start by presenting some of the relevant problems and challenges for analysis of non-Western music traditions that have been studied from an MIR perspective. We will present resources created during the CompMusic project, that are openly available to the community and demonstrate accessing non-Western music data and processing these data (focusing on intonation analysis) with publicly available tools. We will consider research corpora from various music traditions: Hindustani (North India), Carnatic (South India) and Turkish-makam (Turkey).  This session would serve as a quick start for students and researchers without prior experience in analysis of non-Western music and will provide them a good entry point for further investigation. 

Biography

Barış Bozkurt is an Assoc. Prof. of Electrical Engineering at Izmir Democracy University, Turkey. He is a collaborator of the Music Technology Group at the Universitat Pompeu Fabra in Barcelona since 2011. He has obtained his PhD degree (on speech analysis) in 2005 from Faculte Polytechnique De Mons, Belgium and also worked in speech industry after his PhD. Since 2007, he has been teaching in Electrical Engineering and Computer Science departments, and carrying research in the fields of audio signal processing and computational musicology.

Software development best-practices for reproducible research

By  Alastair Porter

Abstract

In software development it is considered a best practice to test code, include documentation, use source code management tools, and make frequent backups. A lot of the time technical research tends to eschew these best practices, resulting in missing data, hard to reproduce results, and wasted time. For researchers who haven't worked in or studied software engineering roles, it can often be confusing to know where to start, or how these best practices improve code quality and save time. In this talk I will show some examples why software engineering best practices are a valuable part of technical research and how to start applying them if you do not know what tools and resources are available.

Ethics working with social media

By  Carlos Castillo

Abstract

Online social data such as user-generated content, expressed or implicit relationships between people, and behavioral traces are at the core of many popular web applications and platforms, driving the research agenda of many researcher in both academia and industry. The promises of social data are many, including the understanding of “what the world thinks” about a social issue, brand, product, celebrity, or other entity, as well as enabling be er decision-making in a variety of elds including public policy, healthcare, and economics.

However, many academics and practitioners are increasingly warning against the naive usage of social data. The seminar will mostly focus on the ethical boundaries and unexpected consequences that are overlooked. Such an overlook can lead to wrong or inappropriate results that can be consequential.

Statistical course and Design of Experiments 

By  Simone Tassani

Abstract

The course of statistics aims to introduce a number of tools for master/Ph.D. students and post docs. The presented tools will play a role in planning many kind of studies, properly analyse the results and understand if data analysed by other researchers are or not reliable.

The course will start with a brief digression over the several implications that bad statistics have today over the scientific society and why every researcher should know the basic concepts behind a statistical analysis.
Than the first part of the course will follow introducing General Linear Modelling and its most common applications: F-test, Monofactorial Analysis of Variance (ANOVA)

In the second class the non-parametric "equivalent" of ANOVA will be introduced: Kruskal-Wallis test.

Monofactorial and multifactorial analysis will be presented, together with the definition of Type I and Type II error, multiple comparison errors and tests for multiple comparison.

Statistical course and Design of Experiments 

By  Simone Tassani

Abstract

The course of statistics aims to introduce a number of tools for master/Ph.D. students and post docs. The presented tools will play a role in planning many kind of studies, properly analyse the results and understand if data analysed by other researchers are or not reliable.

Projects with more than two factors will be presented. This will lead to the presentation of some examples of Design of Experiment (Latin and Greek-Latin squares) for the reduction of the number of experiments and to the concept of orthonormality.
The course will close with the description of linear regression.
