Yuri Kalnishkan: An Identity for Kernel Ridge Regression
Ridge regression is a popular technique in machine learning and statistics with numerous applications. In the talk I will discuss ridge regression in the contexts of functional analysis (reproducing kernel Hilbert spaces) and the theory of random fields (Gaussian covariances) and derive an identity linking the quadratic losses of kernel ridge regression in batch and on-line frameworks. Some corollaries describing the behaviour of the cumulative loss of on-line ridge regression will be obtained. An alternative proof of the identity motivated by the aggregating algorithm will be presented. The results of the talk are covered in the report "An Identity for Kernel Ridge Regression" by F.Zhdanov and Y.Kalnishkan (arXiv:1112.1390v1 [cs.LG]).

John Cremona: Numerical evidence for the BSD Conjecture
The Birch Swinnerton-Dyer Conjectures assert a link between two invariants of elliptic curves, one algebraic and one analytic. Despite 50 years of effort, some partial results of breathtaking ingenuity (and difficulty) and a prize of a million follars offered by the Clay Mathenatics Institute, the conjectures remain wide open in general. Even to verify the conjectures for individual curves is a non-trivial task which relies on deep theoretical results: how do you verify a formula predicting the order of a group when you can neither prove that the group is finite, nor that the number giving the conjectural order is even rational? In the talk, which will assume no prior knowledge of the subject, I will describe the conjectures, what is known, and report on some large-scale numerical evidence for over 1.4 million curves.
