Researchers have developed an amortized approach to Thompson sampling, a strategy for sequential decision-making under uncertainty. This new method allows for the approximation of the Thompson sampling distribution to be available immediately after observations arrive, significantly speeding up the process, especially in continuous action spaces. The technique also enables efficient estimation of expected information gain, which can be used to select more informative samples or optimize designs. This work is demonstrated on simulator-based design problems in synthetic biology with intractable likelihoods. AI
