Tor Lattimore (DeepMind)
Abstract / Description: 

Tor will give a whirlwind tour of a series of recent papers on the information directed sampling algorithm for sequential decision-making. The results come in three flavours. First, generalising and applying the IDS algorithm to problems with a rich information structure such as convex bandits and partial monitoring. Second, showing a connection between the optimisation problem solved by IDS and the optimisation problem that determines the asymptotic lower bound for stochastic structured bandit problems. Third, showing a deep connection between IDS and the mirror descent framework for convex optimisation.


Tor Lattimore is a research scientist at DeepMind working on the foundations of machine learning and especially decision-making. Before joining DeepMind he was an assistant professor at Indiana University and a postdoc at the University of Alberta. He obtained his PhD from the Australian National University under the supervision of Marcus Hutter in 2014.
