Title: Bayesian Optimisation for efficient cosmological model selection


Abstract:  Cosmological model selection, in the framework of Bayesian inference requires the calculation of the Bayesian evidence. This can often be quite challenging, especially if the underlying likelihood function is expensive to evaluate. I will show how a technique called Bayesian Optimisation, based on Gaussian Process regression, can be used to calculate this evidence in far fewer likelihood evaluations, offering a much more efficient approach compared to traditional methods. If time permits, I will also discuss another ongoing project related to the reconstruction of the primordial curvature power spectrum and the equation of state from scalar induced gravitational waves.
