Incremental learning with Gaussian mixture models

Computer Vision Winter Workshop, 2008
In this paper we propose a new incremental estimation of Gaussian mixture models which can be used for applications of online learning. Our approach allows for adding new samples incrementally as well as removing parts of the mixture by the process of unlearning. Low complexity of the mixtures is maintained through a novel compression algorithm. In contrast to the existing approaches, our approach does not require fine-tuning parameters for a specific application, we do not assume specific forms of the target distributions and temporal constraints are not assumed on the observed data. The strength of the proposed approach is demonstrated with an example of online estimation of a complex distribution, an example of unlearning, and with an interactive learning of basic visual concepts.
