Abstract
This thesis implements and compares the performance of several Machine Learning surrogate modeling methods for the inverse high-speed channel design problem. A Tandem Neural Network structure and a User-Choice Inverse Neural Network structure are purposed and thoroughly described for the inverse optimization of high-speed link problems. Comparisons are made between the newly purposed methods and the traditional Machine Learning methods. There are discussions on inverse optimization with mixed continuous-discrete variables. Three high-speed link designs are constructed as examples to evaluate the performance of the Machine Learning methods. Different types of error calculation are displayed to better compare the prediction results of different Machine Learning methods.
