Method and device for operating laser material processing machine

The invention relates to a computer-implemented method for operating a laser material processing machine (1, 2), wherein process parameters (x) are varied with the aid of Bayesian optimization until a result (y) of the laser material processing is sufficiently good, wherein the Bayesian optimization is carried out with the aid of a data-based process model (GP), wherein in a first phase (A), the data-based process model is trained as a function of estimated results (ysim), and wherein in a second phase (B), the data-based process model (GP) is trained as a function of the ascertained result (yexp) resulting upon activation of the laser material processing machine. 本发明涉及一种用于运行激光材料加工机（1、2）的计算机实现的方法，其中，借助贝叶斯优化来改变过程参数（x），直到激光材料加工的结果（y）足够好，其中，借助基于数据的过程模型（GP）进行贝叶斯优化，其中，在第一阶段（A）中基于数据的过程模型（GP）根据估算的结果（ysim）进行训练，并且其中，在第二阶段（B）中基于数据的过程模型（GP）根据在操控激光材料加工机（1、2）时得出的经求取的结果（yexp）进行训练。
