For our purposes, a sequence is defined an ordered sequence of sets of discrete numbers. (If all sets contain exactly one element, the sequence is a string. If there is only one set, it reduces to itemset mining.) This definition of sequence is flexible enough to model a number of interesting problems and has been used successfully for human action classification in video data and web clickstream mining. </p> <p>The pboost toolbox includes source codes for the following functionalities: </p> <pre><code>* PrefixSpan frequent subsequence mining (frequency defined either by minimum support threshold or by top-K frequent subsequences) * Discriminative subsequence mining * nu-LPBoost 2-class classifier * nu-LPBoost 1.5-class (one class with negative examples) classifier * DDAG-decomposition multiclass classifier * Matlab wrappers to all of the above functionality, as well as glue code to the gboost toolbox. </code></pre></html>sebastian nowozinTue, 13 Nov 2007 08:48:28 -0000http://mloss.org/software/rss/comments/20http://mloss.org/software/view/20/classification
