Description
  • Článek zkoumá model klasifikačních stromů se změkčenými větveními, který zavedl Quinlan (1993) a je implementován v C4.5, ale s podstatně odlišným algoritmem pro trénování. Metoda využívá simulované žíhání a je tedy poměrně výpočetně náročná. Na druhé straně dovoluje nastavovat změkčená větvení ve skupinách uzlů způsobem, který lépe odpovídá interakcím mezi prediktory než v původní metodě. Naše numerické výpočty s daty odvozenými z experimentu z fyziky elementárních částic ukazuje, že kromě očekávané lepší aproximace trénovacích dat byla dosažena i menší generalizační chyba. (cs)
  • The current paper uses the model of trees with soft splits suggested by Quinlan and implemented in C4.5, but with a substantially different the training algorithm. The method uses simulated annealing, so it is quite computationally expensive. However, this allows to adjust the soft thresholds in groups of the nodes simultaneously in a way that better captures interactions between several predictors than the original approach. Our numerical test with data derived from an experiment in particle physics shows that besides the expected better approximation of the training data, also smaller generalization error is achieved.
