On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
This talk will deal with optimization problems in a statistical learning setup where the learner has no access to unbiased estimators of the gradient of the objective function. It includes stochastic optimization with zero-order oracle, continuum bandit and contextual continuum bandit problems. I’ll give an overview of recent results on minimax optimal algorithms and fundamental limits for these problems.
