Abstract: Online feature selection with streaming features refers to applications where the knowledge of the full feature space is unknown in advance and features flow in one by one over time. This is in contrast with traditional online learning methods that only deal with sequentially added data instances, with little attention being paid to streaming features. The critical challenges for online streaming feature selection include (1) the continuous growth of feature volumes over time, (2) a large feature space, possibly of unknown or infinite size, and (3) the unavailability of the entire feature set before learning starts. This talk introduces our recent research efforts on online streaming feature selection to select strongly relevant and non-redundant features on the fly.
