Abstract
One of most promising techniques of knowledgebase modeling today is machine
learning, whereby decision trees play an important role in expressing knowledge
by inductive methods. It is known, however, that desion tree methods have
weak points. One of potential problems lies in the heterogenity of distribution
classification attributes: classes with few instances yield poor description
and may disappear alltogether. Another problem concerns the treatment of
new instances during learning, so noise is not confused with data announcing
a class of interest. The paper discusses these and other problems, in particular
comparing criteria for growing decision trees. The framework of analysis
is that of stochastic control theory and algorithmic complexity.
