Big Data Technologies: spotlight on NoSQL, NewSQL and Spark

Patrick Valduriez

The ability to produce high-value information and knowledge from big data makes it critical for many applications such as decision support, forecasting, business intelligence, research, and (data-intensive) science. However, processing and analyzing massive, complex data is hard, if not impossible, using traditional data management tools, e.g., SQL databases. What we need are technologies that combine new data management techniques (to deal with new kinds of data) with large-scale parallelism in cluster or cloud environments (to provide scalability).  In this talk, I will give a spotlight on recent developments in NoSQL, NewSQL and Spark technologies.

Talk on “Life Science Workflow Services (LifeSWS): motivations and architecture” by Patrick Valduriez, The Data Systems Seminar Series, University of Waterloo, 5 sept 2023

See The Data Systems Seminar Series, University of Waterloo, Canada, Tuesday 5 september 2023.

Life Science Workflow Services (LifeSWS): motivations and architecture

Patrick Valduriez

Inria, University of Montpellier, CNRS, LIRMM, France

Data driven science requires manipulating large datasets coming from various data sources through complex workflows based on a variety of models and languages. With the increasing number of big data sources and models developed by different groups, it is hard to relate models and data and use them in unanticipated ways for specific data analysis. Current solutions are typically ad-hoc, specialized for particular data, models and workflow systems. In this talk, we focus on data driven life science and propose an open service-based architecture, Life Science Workflow Services (LifeSWS), which provides data analysis work- flow services for life sciences. We illustrate our motivations and rationale for the architecture with real use cases from life science.

  • Date : le 5 juin 2023 (09h30 – 17h00).
  • Lieu : Amphithéâtre Jean-Jacques Moreau, campus St Priest, Montpellier.

Un peu de lecture sur le débat de la place de l’informatique dans la société, à l’heure où l’IA met ces questions en lumière. Et un portrait de Patrick par Inria.

Programme : 

  • 09h30 Accueil-café
  • 10h00-12h00
    • Kick-off by Jean-Frédéric Gerbeau – Inria Deputy CEO for Science.

Dbfication or Dbfiction in Deep Learning Activities
Marta Mattoso
COPPE/UFRJ, Rio de Janeiro, Brazil

Database management techniques have a lot to contribute to generating and selecting a deep learning model. In this talk, we present current initiatives of the database community towards using data management techniques to improve deep learning activities, to discuss pros and cons. Then, we will focus on provenance-based user steering to evaluate different neural network execution configurations. Provenance data adds semantics to the metrics of each configuration, which can help humans in evaluating and reproducing the models proposed by automatic tools.

An introduction to physics-informed neural networks
Alvaro Coutinho
COPPE/UFRJ, Rio de Janeiro, Brazil

In this talk we will give a brief introduction to Physics-Informed Neural Networks (PINN), that are neural networks that encode model equations, like Partial Differential Equations (PDE), as a component of the neural network itself. PINNs are nowadays used to solve PDEs, fractional equations, integral-differential equations, and stochastic problems. PINN fits observed data while reducing a PDE residual. We will discuss the basic math and algorithmic steps and show some current advanced applications.
