Patent number: 11960253Abstract: A system and a method for parameter optimization with adaptive search space and a user interface using the same are provided. The system includes a data acquisition unit, an adaptive adjustment unit and an optimization search unit. The data acquisition unit obtains a set of executed values of several operating parameters and a target parameter. The adaptive adjustment unit includes a parameter space transformer and a search range definer. The parameter space transformer performs a space transformation on a parameter space of the operating parameters according to the executed values. The search range definer defines a parameter search range in a transformed parameter space based on the sets of the executed values. The optimization search unit takes the parameter search range as a limiting condition and takes optimizing the target parameter as a target to search for a set of recommended values of the operating parameters.Type: GrantFiled: December 28, 2020Date of Patent: April 16, 2024Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Po-Yu Huang, Chun-Fang Chen, Hong-Chi Ku, Te-Ming Chen, Chien-Liang Lai, Sen-Chia Chang
