• Active feature acquisition for opinion stream classification under drift 

  Shivakumaraswamy, Ranjith; Beyer, Christian; Unnikrishnan, Vishnu; Ntoutsi, Eirini; Spiliopoulou, Myra (Aachen : RWTH, 2019)

  Active stream learning is frequently used to acquire labels for instances and less frequently to determine which features should be considered as the stream evolves. We introduce a framework for active feature selection, ...
• Phase diagram for K(1-x)(NH4)(x)H2PO4 (x = 0 – 0.15) solid solutions embedded into magnetic glasses

  Effect of magnetic field application on phase transition in nanostructured solid solutions (1-x)KH2PO4 – (x)(NH4)H2PO4 at x = 0, 0.05 and 0.15 has been studied by dielectric spectroscopy at B = 0 – 10T. The samples have ...
• Backprojection autofocus of large ships with arbitrary motion for synthetic aperture radar 

  Sommer, Aron (Düsseldorf : VDI-Verlag, 2020-01-14)

  Radar images of the open sea taken by airborne synthetic aperture radar (SAR) show typically several smeared ships. Due to their non-linear motions on a rough sea, these ships are smeared beyond recognition, such that their ...
