Adith Swaminathan and Tobias Schnabel are visiting for one year. They are both PhD students at Cornell University working in the intersection of machine learning and information access. Adith’s main focus is on batch learning from bandit feedback using counterfactual risk estimators, developing the learning algorithms and the underlying theory for principled learning from logged interaction data. Tobias works on principled methods for evaluation, including the evaluation of embedding methods for text and the use of propensity scoring for reducing bias in recommender-system evaluation due to self-selection effects.
Kees Halvemaan joins ILPS to work on the parliamentary search engine search.politicalmashup.nl. He works one day a week in the office of Isaac and Lars. He will focus on collecting data from new countries, linking search results across parliaments, and creating richer analytic and exploratory functionality.
On July 1, Nikos Voskarides, an ILPS alumnus, will join ILPS again, this time as PhD Student. He will be working on the MediaNow project, a collaboration between the Informatics Institute and Department of Media Studies of the University of Amsterdam and the Netherlands Institute for Sound and Vision. Nikos will be supervised by Maarten de Rijke.
