An online non-convex optimization problem is considered where the goal is to minimize the flow time (total delay) of a set of jobs by modulating the number of active servers, but with a switching cost associated with changing the number of active servers over time.

The pulled arm and its instantaneous reward are revealed to the learner, whose goal is to find the best arm by minimising the expected stopping time, subject to an upper bound on the error probability.

A key feature of this algorithm is that it is designed on the basis of an information theoretic lower bound for two-armed instances.

We consider the problem of cost-optimal utilization of a crowdsourcing platform for binary, unsupervised classification of a collection of items, given a prescribed error threshold.

We propose and analyse novel algorithms for this problem, and also establish information theoretic lower bounds on the probability of error under any algorithm.

In this paper, we show that specialized algorithms that exploit such parametric information are prone to inconsistent learning performance when the parameter is misspecified.

We study regret minimization in a stochastic multi-armed bandit setting and establish a fundamental trade-off between the regret suffered under an algorithm, and its statistical robustness.

We also compare the error bounds for our distribution oblivious algorithms with those corresponding to standard non-oblivious algorithms.
