Aims After students have successfully completed the course unit, they should be able to
  • evaluate basic developments and possible applications of artificial intelligence (machine learning) in engineering applications (e.g. mechanical engineering).
  • differentiate and explain essential concepts and (mathematical) methods in Machine Learning.
  • evaluate selected algorithms and models (e.g. from the field of diagnostics/forecasting) with regard to their performance, robustness and quality in engineering terms
  • apply learned skills in the areas of data acquisition and processing, data-based modeling (diagnostics and prognostics), and prescriptive analysis.
  • independently structure simple and medium analysis tasks using process models (CRISP/OSA-CBM), implement them on the basis of data and estimate their economic value
Contents Progressive digitization is opening up new opportunities in the value chain. With the increasing integration of sensors, relevant parameters of systems can be continuously recorded and stored in constantly growing databases. It is thus possible, for example, to monitor the health of technical systems. In addition to conventional approaches based on physical modeling, data-based methods in the field of machine learning have come to the fore in recent years. Corresponding algorithms can train models on the available database, with which new data sets can be interpreted and, for example, converted into a health status.

These approaches are not only interesting from an information technology perspective, but can benefit in particular from the expert knowledge that engineers contribute. Thus, mechanical engineers, for example, are asked to select meaningful metrics that can be transformed into data-based models.

In this lecture, students will get an application-oriented insight into the basics of machine learning based on examples from current research of the participating institutes. The lecture introduces relevant areas of statistics, data mining and algorithm development. Based on the presented use cases, the students learn to collect interesting data from an engineering point of view, to filter the data, to extract relevant features and to build models for diagnosis and prognosis using machine learning methods. Common process models are taught as well as the final evaluation and assessment of the developed methods and models.
