Bayesian optimization. Bayesian optimization is a technique for solving optimization problems where the objective function (i.e., the online metric of interest) does not have an analytic expression, rather it can only be evaluated through some time consuming operation (i.e., a randomized experiment).Recently Bayesian Optimization (BO) has caught on, especially in the machine learning (ML) community, and likely that’ll stick in part because it’s punchier than the alternatives. BO terminology goes back to a paper predating use of GPs toward this end, and refers primarily to decision criteria for sequential selection and model updating.

In this paper we test for mean reversion in the Nordic stock markets using monthly nominal data 1947-1998. By simply account for the heteroscedasticity of the data with a regime-switching model of normal distributions and taking estimation bias into account via a Bayesian approach we can find no support of mean reversion.

Bayesian optimization works by constructing a posterior distribution of functions (gaussian process) that best describes the function you want to optimize. As the number of observations grows, the posterior distribution improves, and the algorithm becomes more certain of which regions in parameter space are worth exploring and which are not, as seen in the picture below. Jun 13, 2019 · Formalism and theory . The objective of state space modeling is to compute the optimal estimate of the hidden state given the observed data, which can be derived as a recursive form of Bayes’s rule (Brown et al., 1998; Chen, Barbieri and Brown, 2010). Bayesian Optimization is a constrained global optimization package built upon bayesian inference and gaussian process, that attempts to find the maximum value of an unknown function in as few iterations as possible. This technique is particularly suited for optimization of high cost functions, situations where the balance between exploration and exploitation is important.
