When applying rules produced by induction from training examples to a test example, there are three possible cases that demand different actions: (i) no match; (ii) single match; and (iii) multiple match. Existing techniques for dealing with the "rst and third cases are exclusively based on probability estimation. However, when there are continuous attributes in the example space, and if these ...

conclusions independent of their level, professional soccer players, need 48 hours to recover after an official match. professionals gain more fatigue than young players after a match, but recover as fast. thus, they recover more efficiently especially due to a better physical condition and fitness training. it is expected that the results showed in the study help elite soccer and fitness coach...

In this paper a new marker-based approach is presented for 3D camera pose tracking in indoor Augmented Reality (AR). We propose to combine a circular fiducials detection technique with a particle filter to incrementally compute the camera 3D pose parameters. In order to deal with partial occlusions, we have implemented an efficient method for fitting ellipse to scattered data. So even incomplet...

Local Process Models (LPM) describe structured fragments of process behavior occurring in the context of less structured business processes. Traditional LPM discovery aims to generate a collection of process models that describe highly frequent behavior, but these models do not always provide useful answers for questions posed by process analysts aiming at business process improvement. We propo...
