Bachelor and Master Theses
On the Evolution of Wearable Sensors Systems in an opportunistic Activity Recognition System [VERSTECKT]
Masterarbeit vom 07. October 2011; offen

Problem Definition: This Master’s Thesis investigates how new sensors can be used in a recognition chain by training them with the existing ones. Thereby, the focus shall be the question how sufficient the dynamic transfer learning approach from a sensor jacket (or alternatively from one or more smart phones) to more unobtrusive sensors (e.g., wrist worn watch, sensor on the shoe), is. As no groundtruth is available, the thesis shall also compare and evaluate different methods to estimate the expected accuracy of the system, when training and using the new sensors. An existing framework is available, which shall be used within this Master’s thesis.

Expected Outcome:

  • Related Work Review
  • Development and Validation of suitable signal processing and machine learning algorithms and autonomous realization of an experiment
  • Evaluation and Experiment


  • Interest in component-based software development (Java, OSGi)
  • Good command of English (understanding of related work; Thesis is preferred written in English)
  • Typesetting using LaTeX (→ Miktex, TeXnicCenter) + BibTeX (→ Jabref)

Time Schedule:

  • Start: flexible, as of now
  • Estimated completion date: within 6 months
