Description

Within the platform development team of the LIRIS, I designed and implement an experimentation platform dedicated to research projects.

This platform will allows researchers to easily deploy and run their experiments on large-scale computer clusters and gather reproducible results.

This project is called PAGoDA, which stands for Plateforme à base de plugins pour les Application biG Data Analytics (Plugins based platform for big data analytics applications).

Responsibilities

Regarding the PAGoDA platform project, my main activities were:

  • Hardware and software architecture design of the platform,
  • Setup tools to automate platform management, mainly via Ansible to:
    • Deploy the virtualized platform (OpenStack),
    • Deploy and configure containerization and orchestration tools, such as Docker, Rancher, Kubernetes,
  • Evaluation of different monitoring systems and setup prototype of the platform monitoring using Prometheus, Grafana and the Elastic Stack,
  • Write technical documentation using MkDocs.

In parallel with those activities, I contributed to the setup of tooling for Continuous Integration (CI), such as:

  • Automatic provisioning and deployment of Gitlab Runners,
  • Setup of standard CI jobs around various CNRS projects for instance to deploy automatically documentation, run tests and linters.

I also offered internal training in the laboratory about Git and about data security (gpg, KeepassXC, Hard Drive Encryption).

Description

Realization of a research project associated to the ANR SoLSTiCE project aiming to develop new models and tools to represent 2D (images) and 2D+t (videos, cellular automata) data.

During that time, I went from almost zero knowledge on the subject of data mining to the implement of new algorithm which I compared to the current state-of-the-art.

This project led me to my thesis defense called Spatio-temporal grid mining applied to image classification and cellular automata analysis.

Responsibilities

The main activities I had were:

  • Development of tools and algorithm to perform grid mining, which is a subset of graph mining,
  • Plan and perform data experimentations,
  • Reading and understanding of many research papers on the subject,
  • Autonomous work.
