Action Scientific computing,BigData,AI

Heads :  Thomas PELLEGRINI and Franck RAVAT

The priority strategic action about “Scientific Computing, big Data and AI” is an evolution of the strategic axis about “Big Data and Scientific Computing” that worked from 2007 to 2017.

Until 2017, the strategic axis gathered IRIT researchers and projects dealing with big data analysis, algorithms, architectures and frameworks to manage, process, analyze and produce knowledge and value from complex, heterogeneous, large datasets or dataflows. The availability of huge data sets increased the success of machine learning algorithms, and the advances of deep learning in statistic AI, so that many research issues are shared by the data and AI communities. In order to increase synergies between IRIT research groups in machine learning, data science and other strong topics in AI, it was agreed with he IRIT AI department to extend the frontiers of the strategic action to AI, Big Data and scientific computing.

The missions of the strategic action are to ease information exchange regarding call for projects, events and any initiative about data and AI; to foster collaborations involving various competencies within IRIT, as well as cross-disciplinary collaborations with other labs in Toulouse that require data intensive use or generation; to promote the use and evolution of the OSIRIM data storage and computing platform, and to increase the visibility of research work and results from IRIT groups, targeting other scientific communities and industry at a local level, and focussing on SIGs like MADICS GDR on Big Data or the Mastodons program at a national level.

To reach these goals, the strategic action used the classical tools of a SIG (monthly meetings, mailing list). We also drove IRIT researcher to take part in seminars and industrial fora, we coordinated the joint publication of a special issue about Data Science of Noir sur Blanc, the IRIT journal; we organized several scientific workshops and seminars with invited keynote speakers. Another role of the strategic action was to manage the selection of an annual Master2 internship grant and of one PhD grant every two years, promoting inter-group collaborations on research dealing with “real” big data.

  1. Primary data collection and metadata generation: numeric, text, video, sound, satellite images, sensor data, social data, news, etc.datasets storage, filtering, quality assessment, data indexing; semantic representations of metadata, data enrichment with open data.
  2. Data storage, data repositories: data filtering and preliminary processes, big and heterogeneous data storage platforms; security and access issues (evaluation of no-SQL data repositories);
  3. Data aggregation, integration, modeling and management: virtual models, distributed architectures and networks for big data (grids, processing clusters); complex, real time and heterogeneous data repair and integration (virtual modeling, ontology-based semantic data integration); uncertainty management ;
  4. Data exploitation and processing: algorithms for data indexing, search, querying and mining recherche; machine learning algorithms: statistical and deep learning of data structures and représentations, optimization, dimension reduction and matrix computing for processing and analyzing images, natural language in text, genomic data, videos, sounds (music, oral natural language, noise); models for information retrieval, for high performance scientific computing; knowledge representation and engineering, ontologies, non monotonous reasoning, managing uncertain and fuzzy knowledge, models of argumentation.
  5. Infrastructures and management for data management: grids and distributed architectures for data storage and scientific computing, cost and energy optimization, middleware for data and service management, virtual environments.
  6. data querying and visualization: searching social media and data flows, distributed querying over distributed datasets and consistency management of the answers; natural language queryies; providing rapid access to large heterogeneous datasets; distributed inference and semantic search on large datasets and IoT data, industrial data visualization combining several modalities and levels of detail.
