Constraining the lives and times of exoplanets through evolutionary Bayesian retrievals
Harrison Nicholls, Tim Lichtenberg, Ben Riegler +2
Static retrieval frameworks are leading tools for interpreting exoplanet observations, yet time-independent modelling leaves them prone to degeneracy and unable to resolve exoplane…

Gaussian Mean Field Variational Inference can Overestimate Predictive Variance
James Odgers, Ben Riegler, Siddharth Swaroop +1
Mean Field Variational Inference (MFVI) is widely understood to underestimate posterior variance. By analysing conjugate Bayesian Linear Regression (BLR), we show that this charact…

Standard Acquisition Is Sufficient for Asynchronous Bayesian Optimization
Ben Riegler, James Odgers, Vincent Fortuin
Asynchronous Bayesian optimization is widely used for gradient-free optimization in domains with independent parallel experiments and varying evaluation times. Existing methods pos…
