The fourth colloquium on Innovation in Modern Languages Education, which takes place at Cardiff University, will be an opportunity for members of the GW4 to network, share expertise and start new scholarly collaborations.

The purpose of the workshop is to bring to Cardiff world-leading scientists working particularly in the spectral theory of isotropic random fields, astrophysics and data analysis of Planck and Euclid missions. The invited talks will cover spectral theory of isotropic random fields, big data analysis of real cosmological data and related topics. The key general question to be addressed at the workshop are: statistical techniques for a big data analysis of spherical isotropic random fields (including tensor-valued random fields) and application to real and simulated cosmological data.
