Measurements with Noise: Bayesian Optimization for Co-optimizing Noise and Property Discovery in Automated Experiments
TLDR
Bayesian optimization framework that co-optimizes measurement noise and target property in automated experiments, validated with simulations and real-world PFM.
Reasoning
The paper presents a novel BO workflow integrating noise optimization, which is a clear strength. It is validated with both simulations and real-world experiments (PFM), adding credibility. However, the abstract lacks details on scalability or comparison to baselines, and the scope is limited to materials science.

- Integration of intra-step noise optimization into automated experimental cycles via Bayesian optimization
- Introduction of time as an additional input parameter to simultaneously optimize target property and measurement noise
- Two novel approaches: reward-driven noise optimization and a double-optimization acquisition function
Methodology
A Bayesian optimization workflow that co-optimizes the target property and measurement noise by incorporating time as an input parameter, balancing signal-to-noise ratio and experimental duration. Two strategies are explored: reward-driven noise optimization and a double-optimization acquisition function. The method is validated through simulations and real-world Piezoresponse Force Microscopy (PFM) experiments.
Key Results
The approach successfully optimized measurement duration and property exploration in both simulations and PFM experiments, improving data quality and reducing resource expenditure.
