Celestial charges from twistor space
Kmec, A
Learn from founders and investors who've built extraordinary ventures from the ground up, then put those lessons into practice. Spend four weeks of the Easter vacation working with a team in Oxford, turning your own idea or Oxford research into something real.
Through the Certificate in Entrepreneurship and Innovation, you'll experience what it takes to build a venture first-hand, with a £1,000 bursary for every participant over the Easter vacation. Applications close at 5 pm on Wednesday 2 December.

On fraudulent stochastic algorithms
Laurent Miclo
(Abraham de Moivre International Research Laboratory Imperial College London and CNRS)
Abstract
We introduce and analyse the almost sure convergence of a stochastic algorithm for the global minimisation of smooth functions. This diffusion process is called fraudulent because it requires the knowledge of minimal value of the function. Nevertheless, its investigation is not without interest, since in particular it appears as the limit behaviour of non-fraudulent and time-inhomogeneous swarm mean-field algorithms for global optimisation or in stochastic gradient descent algorithms in over-parametrised deep learning applications.
The talk is based on collaborations with Benaïm, Bolte and Villeneuve.
