Based on Botorch’s tutorial [1] The model consists of a list of mono objective models. The likelihood at each point is the sum of all GP’s likelihood. The acquisition optimization should now optimize multiple objectives at one. To do so in this example we illustrate an approach called qNParEGO [5].
