Empirical Analysis of Stochastic Local Search Behaviour: Connecting Structure, Components and Landscape

Stochastic Local Search algorithms (SLS) are a class of methods used to
tackle hard combinatorial optimization problems. Despite not providing, in
most cases, any guarantee on the quality of the final solution, they are often
able to produce high quality solutions in a relatively short time. They are
therefore routinely used in countless real world applications, and their wide
applicability generates in turn a lot of research interest, both from a theo-
retical perspective and with applications on countless problems. There are

Mixture Domain Adaptation to Improve Semantic Segmentation in Real-World Surveillance

Various tasks encountered in real-world surveillance can be addressed by determining posteriors (e.g. by Bayesian inference or machine learning), based on which critical decisions must be taken. However, the surveillance domain (acquisition device, operating conditions, etc.) is often unknown, which prevents any possibility of scene-specific optimization. In this paper, we define a probabilistic framework and present a formal proof of an algorithm for the unsupervised many-to-infinity domain adaptation of posteriors.

Prédiction de champs physiques

Proposer une méthodologie basée sur le ML pour prédire les champs physiques (2D/3D)

  • Prédiction de champs physiques "en temps réel"
  • Fusionner des données hétérogènes (données expérimentales, données simulées de différents niveaux de fidélité)
  • Hybridation de connaissance a priori / experte avec le ML via des réseaux de neurones informés (par la physique)

Prédiction, gestion et optimisation de la performance énergétique basées sur l'apprentissage automatique en vue d'améliorer le processus de prise de décision en matière énergétique

Context

  • Buildings are in charge of more than 40% of power consumption demand and greenhouse gas emissions

  • Need for a better understanding, efficient characterization and prediction of the energy building performance at different scales for informed decision-making to reduce energy costs and consumption

  • Multi-source data (sensors, smart meters, numerical simulations, weather data…)
