Top-down vs. bottom-up methods for hierarchical classification
We deal with hierarchical classification in the general case when an instance could be associated with multiple and/or partial paths in a given taxonomy. We approach the problem from different perspectives: ”top-down vs. bottom-up”, but also ”on-line vs. batch” and ”theoretical vs. experimental”. In this talk, we briefly present our recent research experience on this subject matter.
