The spectacular multimillion-euro heist nobody noticed

BBC News

It has been described as Germany's most spectacular bank heist in years. On a quiet weekend just after Christmas, a group of thieves broke into a High Street bank in the western town of Gelsenkirchen, by boring through a wall with an industrial drill. They looted more than 3,000 safe deposit boxes and made off with millions of euros. Over a month later, police have yet to make an arrest. For the bank's clients, some of whom say they have lost their life savings and precious family jewellery and valuables, this is a time of anger, confusion and shock.


Ridge Regression and Provable Deterministic Ridge Leverage Score Sampling

Neural Information Processing Systems

While ridge regression provides shrinkage for the regression coefficients, manyofthecoefficients remain smallbutnon-zero. Performing ridgeregression with the matrix sketch returned by our algorithm and a particular regularization parameter forces coefficients to zero and has a provable(1+) bound on the statisticalrisk.


A Meta-Analysis of Overfitting in Machine Learning

Neural Information Processing Systems

In each competition, numerous practitioners repeatedly evaluated their progress against a holdout set that forms the basis of a public ranking availablethroughout the competition. Performance on a separate test set used only oncedetermined the final ranking.

Neural Information Processing Systems

We introduce a principled method for performing zero-shot transfer in reinforcement learning (RL) by exploiting approximate models of the environment. Zero-shot transfer in RL has been investigated by leveraging methods rooted in generalized policy improvement (GPI) and successor features (SFs).
