We set the value range for each parameter. The measured Young's modulus is used as an identifier for the crystals, and we use the values from the bending tests. Crystal sizes were defined within the ranges of 0-3000 μm for length, 200-2000 μm for width, and 50-500 μm for thickness. UV light at 365 nm was used for irradiation, with an experimental setup capable of producing an intensity of 2080 mW/cm² at 100% output. Since changing light intensity is easier than changing crystals, we conducted experiments with four additional light intensity conditions besides the suggested one. The four conditions were selected from 10, 25, 50, 75, and 100%, excluding the percentage closest to the Bayesian-suggested value. The explanatory variables were standardized, and iterative regression was performed.
