An Artificial Life Approach for Semi-supervised Learning [chapter]

Lutz Herrmann, Alfred Ultsch
2008 Studies in Classification, Data Analysis, and Knowledge Organization  
An approach for the integration of supervising information into unsupervised clustering is presented (semi supervised learning).  ...  Supervising information can be easily incorporated in such a system through the implementation of special movement strategies. These strategies realize given constraints or cluster informations.  ...  In contrast to semi-supervised classification, semi-supervised clustering methods are not limited to the class labels given in the preclassified input samples.  ...
