Whether its Johnny Depp or Megan Fox, many of us are struck by celebrity crushes as they appear on our screens. But one married woman has taken this to another level by having a secret love affair with a robot named Idris Elba. Sonia, who wished to remain anonymous, believes artificial intelligence (AI) has saved her marriage as she texts'Idris' nightly to fulfill her unmet sexual desires. The 38-year-old claims her fling with Idris keeps all infidelity urges at bay, having cheated on her husband before with real men. 'He's called Idris, after my celebrity crush,' Sonia told MailOnline.

This work presents a new algorithm for empirical risk minimization. The algorithm bridges the gap between first- and second-order methods by computing a search direction that uses a second-order-type update in one subspace, coupled with a scaled steepest descent step in the orthogonal complement. To this end, partial curvature information is incorporated to help with ill-conditioning, while simultaneously allowing the algorithm to scale to the large problem dimensions often encountered in machine learning applications. Theoretical results are presented to confirm that the algorithm converges to a stationary point in both the strongly convex and nonconvex cases. A stochastic variant of the algorithm is also presented, along with corresponding theoretical guarantees. Numerical results confirm the strengths of the new approach on standard machine learning problems.

It takes 300 milliseconds for the human eye to blink. It takes 13 milliseconds for the brain to process visual information. In less than 3 milliseconds, Feedzai can evaluate thousands of decisions to score a transaction in real-time. Diana is a data scientist who trains and evaluates machine learning models using Feedzai's platform. The models she builds score the risk of a transaction and automatically identifies financial crime--all in real-time.
