gMark: Schema-Driven Generation of Graphs and Queries
Radu Ciucanu - Assistant Professor, Université Clermont Auvergne (France), LIMOS laboratory
Abstract
Massive graph data sets are pervasive in contemporary application domains. Hence, graph database systems are becoming increasingly important. In the experimental study of these systems, it is vital that the research community has shared solutions for the generation of database instances and query workloads having predictable and controllable properties. In this talk, I will present the design and engineering principles of gMark, a domain- and query language-independent graph instance and query workload generator. A core contribution of gMark is its ability to target and control the diversity of properties of both the generated instances and the generated workloads coupled to these instances. Further novelties include support for regular path queries, a fundamental graph query paradigm, and schema-driven selectivity estimation of queries. I will finally give an overview on an extension of gMark called EGG (Evolving Graph Generator), a framework for generating evolving RDF graphs based on finely-tuned temporal constraints given by the user.CV
Radu Ciucanu est maître de conférences à l'Université Clermont Auvergne depuis 2016. Avant, il a été postdoc à l'Université d'Oxford et doctorant à l'Université de Lille et Inria. Ses recherches portent sur la gestion de données orientées graphes, la sécurité des calculs distribués dans le cloud, le web sémantique, l'intégration de données, et les interactions entre les bases de données et l'apprentissage automatique.

Jordi Vitrià - Full Professor at the Departement de Matemàtica Aplicada i Anàlisi of the Universitat de Barcelona
Abstract
Deep learning is one of the fastest growing areas of machine learning and a hot topic in both academia and industry. This lecture will try to figure out what are the real mechanisms that make this technique a breakthrough with respect to the past. To this end, we will review some of the most common architectures (CNN, LSTM, etc.) and their applications by following a hands-on approach. By the end of the lecture, attendants will be able to (i) describe how a neural network works and combine different types of layers and activation functions; (i) describe how these models can be applied in computer vision, text analytics, etc.; (iii) develop simple models in Tensorflow.CV
Jordi Vitria joined the University of Barcelona (UB) in 2007 as Full Professor, where he teaches an introductory course on Algorithms and advanced courses on Data Science and Deep Learning. From April 2011 to January 2016 he served as Head of the Applied Mathematics and Analysis Department, UB. He is currently member of the new Mathematics & Computer Science Department at UB. Jordi's research, when personal computers had 128KB of memory, was originally oriented towards digital image analysis and how to extract quantitative information from them, but soon evolved towards computer vision problems. After a postdoctoral year at the University of California at Berkeley in 1993, Jordi focused on Bayesian methods for computer vision methods. Now, he is the head of a research group working in deep learning, computer vision and machine learning.Requirements for participants:
