Seminar Learning



Data, data, data...

One huge, but exciting challenge of the 21th century posed to

mathematicians is the deluge of data, caused by

  • Telecommunication
  • Medicine
  • Genomics
  • Social Networks
  • Astronomy
  • ...

Various types of data

  • 1D functions: Signals
  • 2D functions: Images
  • 3D functions: Videos
  • >= 1000D function: High-Dimensional Data
  • Functions on manifolds and manifold-valued functions
  • Functions on graphs

Key approaches

  • Applied Harmonic Analysis – Finding suitable structured representations!
  • Deep Neural Networks – Learning representations, in particular, for classification
  • Compressed Sensing – Acquiring only the compressed part of data
    This can be used to solve linear inverse problems in general.
  • Machine Learning – Find patterns in data
  • Spectral Theory (on Graphs) – Analyze the spectrum of data


The seminar takes place in the lecture room IBZ-302. The schedule was fixed as follows
