【 摘 要 】

We propose to use two lectures (out of the given triplet of three lectures) in order to define a direction of prediction, which includes the set of pre- dicted lectures accompanied by the corresponding frequencies. The relevance of the whole predicted set is calculated according to the remaining third lecture. Further improvements were achieved with homogeneous ensembles, based on the random sampling known, also, as bagging. The experimental results were obtained online during the VideoLectures.Net ECML/PKDD 2011 Discovery Challenge (Track N2).
