no code implementations3 Jun 2019 Róbert Busa-Fekete, Dimitris Fotakis, Balázs Szörényi, Manolis Zampetakis

The main result of the paper is a tight sample complexity bound for learning Mallows and Generalized Mallows Model.

Bandit Multiclass Linear Classification: Efficient Algorithms for the Separable Case

no code implementations6 Feb 2019 Alina Beygelzimer, Dávid Pál, Balázs Szörényi, Devanathan Thiruvenkatachari, Chen-Yu Wei, Chicheng Zhang

Under the more challenging weak linear separability condition, we design an efficient algorithm with a mistake bound of $\min (2^{\widetilde{O}(K \log^2 (1/\gamma))}, 2^{\widetilde{O}(\sqrt{1/\gamma} \log K)})$.

Online F-Measure Optimization

no code implementations NeurIPS 2015 Róbert Busa-Fekete, Balázs Szörényi, Krzysztof Dembczynski, Eyke Hüllermeier

In this paper, we study the problem of F-measure maximization in the setting of online learning.

Online Rank Elicitation for Plackett-Luce: A Dueling Bandits Approach

no code implementations NeurIPS 2015 Balázs Szörényi, Róbert Busa-Fekete, Adil Paul, Eyke Hüllermeier

We study the problem of online rank elicitation, assuming that rankings of a set of alternatives obey the Plackett-Luce distribution.

Optimistic Planning in Markov Decision Processes Using a Generative Model

no code implementations NeurIPS 2014 Balázs Szörényi, Gunnar Kedenburg, Remi Munos

We consider the problem of online planning in a Markov decision process with discounted rewards for any given initial state.
