TI  - Autoassociative MLP in sleep spindle detection.
PG  - 183-93
AB  - Spindles are one of the most important short-lasting waveforms in sleep EEG. They 
      are the hallmarks of the so-called Stage 2 sleep. Visual spindle scoring is a 
      tedious workload, since there are often a thousand spindles in one all-night 
      recording of some 8 hr. Automated methods for spindle detection typically use 
      some form of fixed spindle amplitude threshold, which is poor with respect to 
      inter-subject variability. In this work a spindle detection system allowing 
      spindle detection without an amplitude threshold was developed. This system can 
      be used for automatic decision making of whether or not a sleep spindle is 
      present in the EEG at a certain point of time. An Autoassociative Multilayer 
      Perceptron (A-MLP) network was employed for the decision making. A novel training 
      procedure was developed to remove inconsistencies from the training data, which 
      was found to improve the system performance significantly.
