Hi Everyone, In the UCB acquisition function (https://botorch.org/api/_modules/botorch/acquisition/analytic.html#UpperConfidenceBound) does the posterior use the observation noise in computing the sigma term? Or not? I'm new to botorch so a bit hard for me to tell from the code. Thanks, |

Hi Dave. It doesn't use the observation noise in the posterior. By default botorch posteriors do not include the observation noise unless 'observation_noise=True' is included in the 'model.posterior(...)' call. |
