Web crawling is the problem of keeping a cache of webpages fresh, i.e., having the most recent copy available when a page is requested. This problem is usually coupled with the nat…
Adaptive scale-invariant online algorithms for learning linear models
Michał Kempka, Wojciech Kotłowski, Manfred K. Warmuth
We consider online learning with linear models, where the algorithm predicts on sequentially revealed instances (feature vectors), and is compared against the best linear function…
Bandit Principal Component Analysis
Wojciech Kotłowski, Gergely Neu
We consider a partial-feedback variant of the well-studied online PCA problem where a learner attempts to predict a sequence of -dimensional vectors in terms of a quadratic loss…
