Astrophysics meets data science

Project organisation

The Hyperstars collaboration is a combination of two experts in astrophysics specialized in hyper-spectral data and numerical simulations of the star formation process, and five experts in data science covering a large range of expertise: clustering, data mining, machine learning, data quality, inverse problem, source separation, and optimisation on GPU architecture. All participants of the project are in the Paris area.

Hyperstars is funded by Mastodons, an initiative of the Mission Interdisciplinarité du CNRS, and by DIM-ACAV+.
