In this paper we quantify an achievable error-exponent for the problem of content identification from a large database based on noisy queries.

In many scientific and engineering applications, we are tasked with the optimisation of an expensive to evaluate black box function f . Traditional methods for this problem assume just theâ€¦ (More)

The problem of learning the structure of a high dimensional graphical model from data has received considerable<lb>attention in recent years. In many applications such as sensor networks andâ€¦ (More)

This paper investigates the problem of active learning for binary label prediction on a graph. We introduce a simple and label-efficient algorithm called Sfor this task. At each step, Sselects theâ€¦ (More)
