We propose a traffic jam prediction method based on mining frequent patterns correlated to traffic jams. For traffic jam prediction at a given sensor, first, we apply a one-dimensional clustering scheme to identify automatically which sensors are and in what degree correlated to the given sensor in terms that certain volume values with a compact distribution co-occur frequently with the traffic jams...
We propose a new outlier generation approach for one-class random forests (OCRF), a recently developed one-class classifier. The proposed method makes use of a positive and unlabeled learning (PUL) algorithm to generate outliers from the unlabeled samples. The outlier samples generated and the target samples are then used to train an OCRF classifier for one-class classification. The proposed method...
