We propose a contribution to the PKDD-2002 discovery challenge on the hepatitis dataset. This challenge aims at discovering regularities over patients strucked down by chronic hepatitis. Our approach addresses the problem of multi-relational Data Mining, extracting probabilistic tree patterns from a database using Grammatical Inference techniques. We propose to use a representation of the database by trees in order to extract these patterns. They provide a natural way to represent structured… CONTINUE READING
