Robust non-negative dictionary learning
Webtrackers use negative samples to avoid the drifting problem. A natural attempt is to combine the two approaches to give a hybrid approach, as in [31]. Besides object trackers, some other techniques related to our proposed method are (online) dictionary learning and (robust) non-negative matrix factorization (NMF).
