To comply with the global market demands on both quality and efficiency in the manufacturing industry, this book presents the work on developing an intelligent on-line monitoring system for sheet metal stamping processes. It focuses on solving three major questions: (1)how to effectively measure and select the features from the appropriate sensor signals; (2)how to define an effective and efficient learning algorithm to acquire the knowledge from the limited training samples; and (3) how to generate an accurate and simple criterion of the decision making for on-line application. Support vector machine (SVM) technique has been well developed and applied in the work. Through studying the noise density using support vector regression technique, a new approach to measure similarity of the signals is proposed. It helps us to construct a mathematical model to describe the strain signals, which is able to compare the dynamic and real-time data. More important to engineering...
Только что получила второй курсовик!!! Спасибо вам огромное за выполненную вами работу!!! Я думаю преподаватели останутся в таком же восторге как и мы!!! Спасибо вам за скидку!!! Было очень приятно с вами работать!!! Всего вам хорошего!
