Signal Detection Using Ica : Application to Chat Room Topic Spotting

  title={Signal Detection Using Ica : Application to Chat Room Topic Spotting},
  author={Thomas Kolenda and Lars Kai Hansen and Jan Larsen},
Signal detection and pattern recognition for online grouping huge amounts of data and retrospective analysis is becoming increasingly important as knowledge based standards, such as XML and advanced MPEG, gain popularity. Independent component analysis (ICA) can be used to both cluster and detect signals with weak a priori assumptions in multimedia contexts. ICA of real world data is typically performed without knowledge of the number of non-trivial independent components, hence, it is of… CONTINUE READING
