Abstract

fetched live from OpenAlex

Micro-electromechanical systems (MEMS) sensors and actuators are widely used in a variety of applications, from medical imaging to space telecommunications, making their optimal design crucial. Designing MEMS is a time-consuming process that requires numerous iterations of resource-intensive simulations to evaluate potential designs. As the number of design variables and objectives grows, the complexity and required computational time for this process also increase significantly. Consequently, most efforts to tackle this challenge have focused on scenarios with limited design parameters and a single objective, leaving the area of efficient multi-objective optimization (MOO) for MEMS devices relatively unexplored. In this study, we employ surrogate-assisted design optimization for a MEMS Lorentz force actuator. During an iterative multi-objective optimization process, surrogate models are utilized for performance evaluation of designs instead of numerical simulations. This approach enables us to achieve optimal designs that satisfy all objective constraints using as low as 2% of the number of simulations required compared to case surrogate models are not used, greatly facilitating design optimization. Additionally, we investigate how the number of training simulations and their preprocessing impact the accuracy of the surrogate models and the optimization results.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
