1. 1. Scalable Validation of Data Streams

   Författare :Cheng Xu; Tore Risch; Byung-Suk Lee; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Data Stream Management; Distributed Data Stream Processing; Data Stream Validation; Anomaly Detection; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

   Sammanfattning : In manufacturing industries, sensors are often installed on industrial equipment generating high volumes of data in real-time. For shortening the machine downtime and reducing maintenance costs, it is critical to analyze efficiently this kind of streams in order to detect abnormal behavior of equipment. LÄS MER

3. 2. Machine Learning Based Methods for Virtual Validation of Autonomous Driving

   Författare :Tobias Johansson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AD Simulation; Virtual Validation; Sensor Error Modeling; Falsification; Autonomous Driving; Validation; Mixture Density Networks;

   Sammanfattning : During the last decade, automotive manufacturers have introduced increasingly capable driving automation functions in consumer vehicles. As the functionality becomes more advanced, the task of driving moves from the human to the car. Hence, making sure that autonomous driving (AD) functions are reliable and safe is of high importance.
