Ensemble- and Distance-Based Feature Ranking for Unsupervised Learning
Matej Petković, Dragi Kocev, Blaž Škrlj +1
In this work, we propose two novel (groups of) methods for unsupervised feature ranking and selection. The first group includes feature ranking scores (Genie3 score, RandomForest s…
Feature Ranking for Semi-supervised Learning
Matej Petković, Sašo Džeroski, Dragi Kocev
The data made available for analysis are becoming more and more complex along several directions: high dimensionality, number of examples and the amount of labels per example. This…
Fuzzy Jaccard Index: A robust comparison of ordered lists
Matej Petković, Blaž Škrlj, Dragi Kocev +1
We propose Fuzzy Jaccard Index (FUJI) -- a scale-invariant score for assessment of the similarity between two ranked/ordered lists. FUJI improves upon the Jaccard index by incorpor…
Oblique Predictive Clustering Trees
Tomaž Stepišnik, Dragi Kocev
Predictive clustering trees (PCTs) are a well established generalization of standard decision trees, which can be used to solve a variety of predictive modeling tasks, including st…
