9 Reasons Why PC Gaming Is Better Than Consoles

It seems unlikely that the PC versus console debate will ever be settled; both platforms have legions of fans. However, if you happen to be a console lover curious about the merits of PC gaming, this list will help you appreciate why it can be even more exciting than a few sessions with an Xbox or PlayStation. 1. PC games are cheaper, and you are more likely to find them on sale Virtually every console game is more expensive than…

Open-sourcing FBGEMM for server-side inference

Facebook is open-sourcing FBGEMM, a high-performance kernel library, optimized for server-side inference. Unlike other commonly available libraries, FBGEMM offers optimized on-CPU performance for reduced precision calculations used to accelerate deep learning models. The library has been deployed at Facebook, where it’s delivered greater than 2x performance gains with respect to our current production baseline. FBGEMM offers high performance on native tensor formats (unlike many other libraries that require repacking tensors for best performance). It offers substantial plug-and-play functionality and performance…

Preschool children show awake responses to naptime nonsense words — ScienceDaily

Of all of our senses, hearing is the only one that has long been suspected as being “on” all the time — even in our sleep. Sounds that occur during the night have a way of registering in the brain. Now a group of scientists in Tennessee is reporting the results of studies on what is heard and not heard during sleep and what that might mean for a developing brain. At the upcoming Acoustical Society of America’s 176th Meeting,…

Sensor gives farmers more accurate read on plant health, provides valuable crop data

Computer model could improve human-machine interaction, provide insight into how children learn language — ScienceDaily

Children learn language by observing their environment, listening to the people around them, and connecting the dots between what they see and hear. Among other things, this helps children establish their language’s word order, such as where subjects and verbs fall in a sentence. In computing, learning language is the task of syntactic and semantic parsers. These systems are trained on sentences annotated by humans that describe the structure and meaning behind words. Parsers are becoming increasingly important for web…

The company offers an alternative approach to satellite ground communications, enabling customers to use their resources more efficiently via a modern and secure software solution. Software is the key to developing the full potential of space via satellites providing efficient and effective services. The value of software to space systems has greatly increased over the last decades, reflecting the growing functionality and autonomy…

High-performance components made by electroplating

The balance wheel is the beating heart of every mechanical watch mechanism. The delicate springs are usually made of cast, forged Nivarox alloy. At Empa a new generation of balance springs is produced with means of electroplating. Credit: A. Lange & Söhne What happens when something keeps getting smaller and smaller? This is the type of question Empa researcher Johann Michler and his team are investigating. As a by-product of their research completely novel watch springs could soon be used…

3-D-knitted shells save on construction materials and time

Credit: Lex Reiter With just the press of a button, ETH researchers knit a textile that serves as the primary shaping element for curved concrete shells. Now they have used the new technology to create a five-tonne concrete structure for an exhibition in Mexico City. The heart of the four metre tall curved concrete shell is knitted. The structure‘s formwork is a textile supported by a steel cable-net. The prototype KnitCandela marks the first application that this technology is being…

The Journey Continues – Netflix TechBlog – Medium

by Zhi Li, Christos Bampis, Julie Novak, Anne Aaron, Kyle Swanson, Anush Moorthy and Jan De Cock How will Netflix members rate the quality of this video — poor, average or excellent? Which video clip looks better — encoded with Codec A or Codec B?For this episode, at 1000 kbps, is it better to encode with HD resolution, with some blockiness, or will SD look better? These were example questions we asked ourselves as we worked towards delivering the best quality of experience for Netflix…

Michelangelo PyML: Introducing Uber’s Platform for Rapid Python ML Model Development

By Kevin Stumpf, Stepan Bedratiuk, and Olcay Cirit As a company heavily invested in AI, Uber aims to leverage machine learning (ML) in product development and the day-to-day management of our business. In pursuit of this goal, our data scientists spend considerable amounts of time prototyping and validating powerful new types of ML models to solve Uber’s most challenging problems (e.g., NLP based smart reply systems, ticket assistance systems, fraud detection, and financial and marketplace forecasting). Once a model type…
