The performance of the (multi-class) classifier thus produced strongly depends on the structure of the decomposition. In this paper, we conduct an empirical study, in which we compare existing heuristics for selecting a suitable structure in the form of a nested dichotomy. Moreover, we propose two additional heuristics as natural completions. One of them is the Best-of-K heuristic, which picks the (presumably) best among K randomly generated nested dichotomies. Surprisingly, and in spite of its simplicity, it turns out to outperform the state of the art."}],"file":[{"date_created":"2018-11-02T15:30:57Z","creator":"ups","success":1,"content_type":"application/pdf","file_id":"5305","file_size":1482882,"access_level":"closed","file_name":"OnTheEffectivenessOfHeuristics.pdf","date_updated":"2018-11-02T15:30:57Z","relation":"main_file"}],"date_created":"2018-06-29T07:44:26Z","type":"journal_article","department":[{"_id":"355"}]}
