Efficient Classification of Multi-Labelled Text Streams by Clashing

no code implementations12 Apr 2016 Ricardo Ñanculef, Ilias Flaounas, Nello Cristianini

Our method is composed of an online procedure used to efficiently map text into a low-dimensional feature space and a partition of this space into a set of regions for which the system extracts and keeps statistics used to predict multi-label text annotations.
