Abstract
WEAVE-QSO and J-PAS are two large astrophysical surveys active from 2022 to 2029, on two major observatories, supported by two international collaborations: WEAVE-QSO (European) and J-PAS (mainly Brazilian-Spanish). These two surveys are partners towards a common goal: cosmology and galaxy formation in the first half of the history of the universe using data of unprecedented quality and size. J-PAS does this by performing imaging in 56 colours and WEAVE-QSO follows this up with spectroscopy. The exploitation of this data presents a variety of challenges and opportunities that we seek to address through machine learning. In some cases, the first steps have been undertaken and preliminary results are already available, while in other cases the projects are in the cradle. The leads of these surveys propose to pool the expertise of the partners and bring together innovative methods for the fullest exploitation of our large common data set. (AU)
