Abstract

The main goal of this postdoc project is to develop machine learning based computational methods to speed up both annotation and classification of plankton images, minimizing the required effort from the expert. The method should be able to effectively reuse previously generated knowledge, quickly producing new classifiers adapted to new imaging or use conditions. Unsupervised and semi-supervised machine learning approaches, possibly including user-interaction mechanisms, as well as techniques related to novelty detection and class imbalance treatment, are some of the research topics to be explored.
