Astrophysics meets data science

Project organisation

The Hyperstars collaboration is a combination of experts in astrophysics specialized in hyper-spectral data, interstellar dust modelling and numerical simulations of the star formation process, and 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 received funds from Mastodons, an initiative of the Mission pour l'Interdisciplinarité du CNRS, and from DIM-ACAV+.
