New 'bias against' criterion enhances Bayesian experimental design

Researchers have introduced a new criterion called "bias against" (BA) for Bayesian optimal experimental design (BOED), aiming to control misleading evidence more effectively than the traditional expected information gain (EIG) criterion. This new approach is integrated into a policy-based deep adaptive design framework, utilizing Monte Carlo approximations and stochastic gradient methods for optimization. The effectiveness of BA designs is demonstrated through examples, including adaptive designs for complex discrete choice experiments. AI
