Learning issues in image segmentation
Joachim M. Buhmann
Video in druga učna gradiva
Oznake: computer science;image analysis
Image segmentation is often defined as a partitioning of pixels or image blocks into homogeneous groups. These groups are characterized by a prototypical vector in feature space, e.g., the space of Gabor filter responses, by a prototypical histograms of features or by pairwise dissimilarities betwee ...

Information Theoretic Model Selection in Clustering
Joachim M. Buhmann
Video in druga učna gradiva
Oznake: computer science;machine learning;clustering
Model selection in clustering requires (i) to specify a clustering principle and (ii) to decide an appropriate number of clusters depending on the noise level in the data. We advocate an information theoretic perspective where the uncertainty in the data set induces an uncertainty in the solution sp ...

Information Theoretic Model Validation by Approximate Optimization
Joachim M. Buhmann
Video in druga učna gradiva
Oznake: computer science;information theory
Model selection in pattern recognition requires (i) to specify a suitable cost function for the data interpretation and (ii) to control the degrees of freedom depending on the noise level in the data. We advocate an information theoretic perspective where the uncertainty in the measurements quantize ...
