Who is Afraid of Big Bad Minima? Analysis of gradient-flow in spiked matrix-tensor models

Neural Information Processing Systems

When the signal-to-noise ratio is large enough, the success of gradient descent can thus be understood by a trivialisation transition in the loss landscape: either there is only a single minima, or all minima become "good", and no





MND left her without a voice. Eight seconds of scratchy audio gave it back to her

MND left her without a voice. After such a long time, I couldn't really remember my voice, Sarah Ezekiel tells BBC Access All. When I first heard it again, I felt like crying. The onset of motor neurone disease (MND) left Sarah without a voice and the use of her hands at the age of 34. It was within months of her becoming a mum for the second time.



Neanderthals bred with humans 100,000 YEARS earlier than first thought, scientists say - as they discover skeleton of five-year-old crossbreed

Daily Mail - Science & tech

Neanderthals bred with our human ancestors 100,000 years earlier than previously thought, according to a new study. Experts have discovered that a five–year–old child who lived 140,000 years ago had parents from both species. Their fossil – likely a female – was first unearthed 90 years ago in the Skhul Cave on Mount Carmel in what is now northern Israel. A team from Tel Aviv University and the French Centre for Scientific Research conducted a series of advanced tests on the remaining bones, including a CT scan of the skull. 'Genetic studies over the past decade have shown that these two groups exchanged genes,' said lead author Professor Israel Hershkovitz.
