abstract = {During an interactive image retrieval process with
relevance feedback, kernel-based or boosted learning algorithms can
provide superior nonlinear modeling capability. In this paper, we
discuss such nonlinear extensions for biased discriminants, or BiasMap
[1, 2]. Kernel partial alignment is proposed as the criterion for
kernel selection. The associated analysis also provides a gauge on
relative class scatters, which can guide an asymmetric learner, such as
BiasMap, toward better class modeling. We also propose two boosted
versions of BiasMap. Unlike existing approach that boosts feature
components or vectors to form a composite classifier, our scheme boosts
linear BiasMap toward a nonlinear ranker which is more suited for
small-sample learning during interactive image retrieval. Experiments
on heterogeneous image database retrieval as well as small sample face
retrieval are used for performance evaluations.},
