We consider the central problem of exploration versus exploitation that lies at the heart of several dynamic learning problems. We revisit the problem of regret in adaptive control and examine it in the light of recent interest in solving large scale bandit problems. We present a family of schemes that admits simple index policies whose regret performance appears to be near the best apparently currently available, and at low computational complexity per decision. [Joint work with Xi Liu, Ping-Chun Hsieh, and Anirban Bhattacharya].
