Ucb
Much of our work has focused on the design and implementation of a Unix Consultant (UC) program. This system carries out a dialog in English to answer user 's queries about the UNIX operating system. UC comprises a natural language parsing and generation system, a goal analyzer that hypothesizes user 's goals in different contexts, a user model component that allows UC to tailor answers to the ...
متن کاملNew antiepileptic drugs that are second generation to existing antiepileptic drugs.
In the last decade, 10 new antiepileptic drugs (AEDs) have been introduced that offer appreciable advantages in terms of their favourable pharmacokinetics, improved tolerability and lower potential for drug interactions. However, despite the large therapeutic range of old and new AEDs, approximately 30% of the patients with epilepsy are still not seizure free and, consequently, there is a subst...
متن کاملAccelerating AdaBoost using UCB
This paper explores how multi-armed bandits (MABs) can be applied to accelerate AdaBoost. AdaBoost constructs a strong classifier in a stepwise fashion by adding simple base classifiers to a pool and using their weighted “vote” to determine the final classification. We model this stepwise base classifier selection as a sequential decision problem, and optimize it with MABs. Each arm represents ...
متن کاملBrivaracetam: a rational drug discovery success story.
Levetiracetam, the alpha-ethyl analogue of the nootropic piracetam, is a widely used antiepileptic drug (AED) that provides protection against partial seizures and is also effective in the treatment of primary generalized seizure syndromes including juvenile myoclonic epilepsy. Levetiracetam was discovered in 1992 through screening in audiogenic seizure susceptible mice and, 3 years later, was ...
متن کاملThresholding Bandits with Augmented UCB
In this paper we propose the Augmented-UCB (AugUCB) algorithm for a fixed-budget version of the thresholding bandit problem (TBP), where the objective is to identify a set of arms whose quality is above a threshold. A key feature of AugUCB is that it uses both mean and variance estimates to eliminate arms that have been sufficiently explored; to the best of our knowledge this is the first algor...
