The Moto Z2 Play looks very familiar


You probably picked up the Moto Z Play for its long battery life, mid-range price and compatibility with Motrola's flagship modular backs. If you were worried that those components wouldn't work on the next version of the handset, don't -- leaked images of the Moto Z2 Play from TechnoBuffalo suggest that the device will be almost visually identical to the original. Well, there is one notable change: the Moto Z Play's square button has been replaced with a round one. Ultimately, this isn't too much of a surprise -- any drastic changes to the phone's chassis would have made it incompatible with the battery, camera back and other accessories created for the Moto Z line. Keeping the same shape was important.

Factorized Graph Representations for Semi-Supervised Learning from Sparse Data Machine Learning

Node classification is an important problem in graph data management. It is commonly solved by various label propagation methods that work iteratively starting from a few labeled seed nodes. For graphs with arbitrary compatibilities between classes, these methods crucially depend on knowing the compatibility matrix that must be provided by either domain experts or heuristics. Can we instead directly estimate the correct compatibilities from a sparsely labeled graph in a principled and scalable way? We answer this question affirmatively and suggest a method called distant compatibility estimation that works even on extremely sparsely labeled graphs (e.g., 1 in 10,000 nodes is labeled) in a fraction of the time it later takes to label the remaining nodes. Our approach first creates multiple factorized graph representations (with size independent of the graph) and then performs estimation on these smaller graph sketches. We define algebraic amplification as the more general idea of leveraging algebraic properties of an algorithm's update equations to amplify sparse signals. We show that our estimator is by orders of magnitude faster than an alternative approach and that the end-to-end classification accuracy is comparable to using gold standard compatibilities. This makes it a cheap preprocessing step for any existing label propagation method and removes the current dependence on heuristics.

PlayStation 5 May Have Backwards Compatibility Feature, Sony Patent Suggests

International Business Times

Sony hasn't revealed plans for the PlayStation 5 yet, but it looks like one of its features may have already been leaked. According to a recent update to a Sony patent, the PS5 may include backwards compatibility to enable users to play their PlayStation 4 games on the new system. The update to Sony's patent was first reported by PlayStation Universe. The patent was originally filed back in 2015, two years after the launch of the PS4. The updated patent notes, "Backward compatibility testing of software in a mode that disrupts timing."

The 10 Best new Smart TVs

The Independent - Tech

If it's time to replace your TV, and you haven't performed this task for a while, you may find things have changed. The highest-resolution TVs currently routinely available are 4K, also called ultra-high definition (Ultra HD or UHD). This is four times the resolution of high definition (HD). Of course, there's not that much native 4K content available yet, and almost no broadcast 4K – sports channels from Sky and BT are the main exceptions with occasional BBC special events which are delivered via iPlayer. The lack of native 4K content isn't as crucial as when HD, for instance, arrived, as the TVs have upscalers built in, which make HD content look almost as good as 4K.

This rotating house is a true test for roommate compatibility


The installation is called ReActor. Two Russian artists built this house and lived in it for five days as part of a social experiment. Because the rotating house is balanced on a pole, the house can tilt and spin with the wind. The designers had to work together to keep the house balanced.
