• Conference Proceeding: A Novel Criterion for Onset Detection: Differential Information Redundancy with Application to Human Movement Initiation

  ABSTRACT: A new detection criterion based on the change in the marginal information redundancy is presented. By establishing a link with information theory we are able to give an intuitive interpretation of our criterion. The usefulness of the new criterion is demonstrated for a case study of human movement initiation detection from force and torque signals in activity of daily living tasks. Using the new criterion, we achieve a performance that is more in agreement with expert decisions compared with traditional thresholding techniques and the advanced wavelet-based detector and energy detectors.

• Conference Proceeding: Clustering with kernel-based equiprobabilistic topographic maps

  M.M. Van Hulle, K.U. Leuven
  [show abstract] [hide abstract]
  ABSTRACT: A new unsupervised competitive learning rule is introduced which performs equiprobabilistic topographic map formation. The receptive fields are overlapping radially-symmetric kernels of which the radii are adapted to the local input density, together with the weight vectors which define the kernel centers. The application envisaged is density-based clustering
