We introduce an innovative incremental learner called incremental import vector machines (I2VM). The kernel-based discriminative approach is able to deal with complex data distributions. Additionally, the learner is sparse for an efficient training and testing and has a probabilistic output. We particularly investigate the reconstructive component of import vector machines, in order to use it for robust incremental learning. By performing incremental update steps, we are able to add and remove data samples, as well as update the current set of model parameters for incremental learning. By using various standard benchmarks, we demonstrate how I2VM is competitive or superior to other incremental methods. It is also shown that our approach is capable of managing concept-drifts in the data distributions.
