In general, researchers conduct iterative experiments by changing experimental conditions by trial and error. If Artificial Intelligence (AI) could interpret experimental results and design the next experimental condition, then, by utilizing AI and robotic technology, the iterative experimental cycle could be automated, leading to reduced variation due to individual differences, reduced labor costs, and increased instrument utilization rates. This article presents a Bayesian optimization method to automate iterative experiments that include noisy observations. By applying the Bayesian optimization method that we have developed to LC-MS, the instrument parameters for high sensitivity LC-MS measurements can be found efficiently with a small number of measurements.
