Random forests are one of the best performing methods for constructing ensembles. They derive their strength from two aspects:
using random subsamples of the training data (as in bagging) and randomizing the algorithm for learning base-level classifiers
(decision trees). The base-level algorithm randomly selects a subset of the features at each step of tree construction and
chooses the best among these. We propose to use a combination of concepts used in bagging and random subspaces to achieve
a similar effect. The latter randomly select a subset of the features at the start and use a deterministic version of the
base-level algorithm (and is thus somewhat similar to the randomized version of the algorithm). The results of our experiments
show that the proposed approach has a comparable performance to that of random forests, with the added advantage of being
applicable to any base-level algorithm without the need to randomize the latter.
