Päätöspuiden käyttö koneoppimisessa
2017
Päätöspuihin perustuvia menetelmiä ollaan käytetty laajasti koneoppimisen eri tehtävissä. Tämä tutkielma kokoaa tietoa siitä miten ja mihin näitä menetelmiä ollaan käytetty. Käydään läpi yksittäisen päätöspuun luominen datasta ja tämän pohjalta tutustutaan kokoonpanomenetelmiin, joissa kootaan useita päätöspuita. Lopulta tutustutaan vielä joihinkin esiteltyjen menetelmien sovelluksiin. Methods based on decision trees have been utilized widely in different tasks of machine learning. This study compiles information on how and for what purposes have these methods been used. Construction of a decision tree based on data is explained and with that as a basis ensemble methods, which comprise many…
