Learning from partially labelled data -- with confidence AbstractIn this paper, we propose a unifying treatment of several strategies for training mixture models from label-deficient data. After a review of different approaches to estimating classification models on partially labelled data using mixture models, we identify a number of problems which lead us to propose a new EM variant. The aim is to better handle unlabelled data and provide a more confident discrimination decision. This is illustrated by an experimental comparison of the different models on the Leptograpsus crab data.
