Collecting Human Motion Data in Large and Occlusion-Prone Environments using Ultra-Wideband Localization

Janik Kaden, Maximilian Hilger, Tim Schreiter, Marius Schaab et autres

With robots increasingly integrating into human environments, understanding and predicting human motion is essential for safe and efficient interactions. Modern human motion and activity prediction approaches require high quality and quantity of data for training and evaluation, usually collected from motion capture …

Towards Fast Gaussian Process Regression Models: An FPGA-based Implementation of the RBF Kernel Matrix Computation

Anna Zuchna, Yousef Alnaser, Christian Schott, Georg Winkler et autres

Gaussian Process Regression (GPR) is a machine learning technique that, besides predicting certain target values, also quantifies their uncertainty. With that, GPR is increasingly gaining significance for mission-critical applications, such as in the development of virtual metrology for key processes in the …
