Method and device for operating laser material processing machine

The invention relates to a computer-implemented method and device for operating a laser material processing machine (1, 2), in which an estimation result (ysim) which characterizes how good an actual result (yexp) of the laser material processing is determined from a predefined process parameter (x), and in which the process parameter (x) is varied by means of Bayesian optimization using a data-based model, until the actual result (yexp) of the laser material processing is sufficiently good. 用于运行激光材料加工机（1，2）的计算机实现的方法和设备，其中根据预给定的过程参数（x）确定估计结果（ysim），所述估计结果表征激光材料加工的实际结果（yexp）有多好，以及其中借助于贝叶斯优化，利用基于数据的模型来改变所述过程参数（x），直到所述激光材料加工的实际结果（yexp）足够好为止。
