PRX Quantum2021As quantum computers approach the fault tolerance threshold, diagnosing and characterizing the noise on large scale quantum devices is increasingly important. One of the most important classes of noise channels is the class of Pauli channels, for reasons of both theoretical tractability and experimental relevance. Here we present a practical algorithm for estimating the s nonzero Pauli error rates in an

PRX Quantum2021Efficiently estimating properties of large and strongly coupled quantum systems is a central focus in many-body physics and quantum information theory. While quantum computers promise speedups for many of these tasks, near-term devices are prone to noise that will generally reduce the accuracy of such estimates. Here, we propose a sample-efficient and noise-resilient protocol for learning properties of

ICML 20212021Motivated by modern applications, such as online advertisement and recommender systems, we study the top-k eXtreme contextual bandits problem, where the total number of arms can be enormous, and the learner is allowed to select k arms and observe all or some of the rewards for the chosen arms. We first propose an algorithm for the non-eXtreme realizable setting, utilizing the Inverse Gap Weighting strategy

ICDM 20212021Recommending sets of items that include both personalized and compatible items is crucial to personalized styling programs such as Amazon’s Personal Shopper. There is both an extensive literature on learning generic fashion compatibility and also on personalization in fashion. However, recommending pairs of items that the customer would like to wear together is still less studied as it involves learning

AI Magazine2021In this article, we explain why an interventional view of recommendation provides a rigorous framework for thinking about recommender systems—enabling new insights both at a technical level for evaluation and learning, as well as at a conceptual level when we reason about the future of recommender systems. In some respects, the view of recommender systems as autonomous systems that act through their recommendations
