Mining probabilistic tree patterns in a medical database
Amaury Habrard, Bernard Marc, François Jacquenet, Paul Michelon · 2007
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.
