Abstract
Na četiri različita skupa podataka su trenirani algoritmi strojnog učenja; stablo odluke i nasumična šuma. Promatrane su metrike za evaluaciju modela i utrošak memorije, vremena i korištenje procesora za slučajeve kada je nad skupom podataka primijenjena tehnika analize glavnih komponenti i kada nije. Zaključeno je da kvaliteta modela uvelike ovisi o količini atributa, uzoraka, vrijednostima podataka te broju mogućih klasa. Smanjenje dimenzionalnosti skupa podataka može značajno smanjiti utrošak memorije i vremena, te kod manjih skupova podataka se može smanjiti točnost modela.
Abstract (english)
Machine learning algorithms decision tree and random forest, are trained on four different datasets. Parameters observed are scores for evaluating machine learning models, time, memory and processor usage for two separate cases. The first case when models are trained on datasets transformed by using principal component analysis and the second case where models are trained on the original datasets. The conclusion is that the quality of the model is highly dependent upon the number of attributes and rows, the values of the data and the amount of possible classes. Dimensionality reduction can greatly reduce time and memory consumption, but for smaller datasets this comes at the cost of model accuracy reduction.
