However, they suffer from an exponential complexity in terms of the input dimension of the problem. In order to address this issue, we propose a novel variant of random search that exploits negative curvature by only relying on function evaluations.

Recent work has shown that a simple, fast method called Simple Graph Convolution (SGC) (Wu et al., 2019), which eschews deep learning, is competitive with

We identify the information-theoretic threshold below which obtaining a positive correlation with the true cluster means is statistically impossible.

Recently, tensor network (TN) decompositions have gained prominence in computer vision and contributed promising results to high-order data recovery tasks.

Some millionaires might be happy frittering away their hard–earned cash on speed boats, golfing holidays, and perhaps the odd football team or two. But William Sachiti is far from your run–of–the–mill businessman. Much more Blofeld than Bill Gates, Mr Sachiti has decided to use his millions in a far less conventional way. Naturally, that meant buying a Cold War RAF base and firing up the radar station to hunt for UFOs. From his'supervillain lair' in the nuclear bunker beneath former RAF Neatishead, Norfolk, Mr Sachiti is building what may be the world's most sophisticated UFO–hunting machine.
