On Communication Complexity of Classification Problems
Daniel M. Kane, Roi Livni, Shay Moran +1
This work studies distributed learning in the spirit of Yao's model of communication complexity: consider a two-party setting, where each of the players gets a list of labelled exa…
Multi-Armed Bandits with Metric Movement Costs
Tomer Koren, Roi Livni, Yishay Mansour
We consider the non-stochastic Multi-Armed Bandit problem in a setting where there is a fixed and known metric on the action space that determines a cost for switching between any…
Agnostic Learning by Refuting
Pravesh K. Kothari, Roi Livni
The sample complexity of learning a Boolean-valued function class is precisely characterized by its Rademacher complexity. This has little bearing, however, on the sample complexit…
Bandits with Movement Costs and Adaptive Pricing
Tomer Koren, Roi Livni, Yishay Mansour
We extend the model of Multi-armed Bandit with unit switching cost to incorporate a metric between the actions. We consider the case where the metric over the actions can be modele…
