We study primal-dual type stochastic optimization algorithms with non-uniform sampling. Our main theoretical contribution in this paper is to present a convergence analysis of Stochastic Primal Dual Coordinate (SPDC) Method with arbitrary sampling. Based on this theoretical framework, we propose Optimality Violation-based Sampling SPDC (ovsSPDC), a non-uniform sampling method based on Optimality Violation. We also propose two efficient heuristic variants of ovsSPDC called ovsSDPC+ and ovsSDPC++. Through intensive numerical experiments, we demonstrate that the proposed method and its variants are faster than other state-of-the-art primal-dual type stochastic optimization methods.

Information in neural networks is represented as weighted connections, or synapses, between neurons. This poses a problem as the primary computational bottleneck for neural networks is the vector-matrix multiply when inputs are multiplied by the neural network weights. Conventional processing architectures are not well suited for simulating neural networks, often requiring large amounts of energy and time. Additionally, synapses in biological neural networks are not binary connections, but exhibit a nonlinear response function as neurotransmitters are emitted and diffuse between neurons. Inspired by neuroscience principles, we present a digital neuromorphic architecture, the Spiking Temporal Processing Unit (STPU), capable of modeling arbitrary complex synaptic response functions without requiring additional hardware components. We consider the paradigm of spiking neurons with temporally coded information as opposed to non-spiking rate coded neurons used in most neural networks. In this paradigm we examine liquid state machines applied to speech recognition and show how a liquid state machine with temporal dynamics maps onto the STPU-demonstrating the flexibility and efficiency of the STPU for instantiating neural algorithms.

What do you think is a reasonable budget for a gaming PC? originally appeared on Quora: the place to gain and share knowledge, empowering people to learn from others and better understand the world. That said, there are three price points that I think are reasonable and it really comes down to what kind of gaming experience you want to have. For the budget gamer, you're less interested in playing on max settings than you are in being able to play recent games on medium/high and occasionally ultra settings or maybe you're someone who, like me, spends lots of time in games like Diablo III, League of Legends or other slightly older/less demanding games. For gamers in this market, $650 - $750 gives you a pretty decent base rig that has room to grow as your needs grow. In general, at this price point, I'm thinking along lines that look like this: Pentium G4560 3.5GHz Dual-Core, Radeon RX 470 4GB STRIX, Enthoo EVOLV ITX Mini ITX Tower.

Artificial Intelligence has come to mean many things to different people. Some view A.I. as a command-and-response technology that offers one-dimensional, pre-programmed, responses. This command-driven interpretation of artificial intelligence falls short of describing truly dynamic artificial intelligences like Arghon. As a high-performance A.I., Arghon seeks to provide practical services and useful information quickly, based on its deep understanding and personalized interactions with our users. Having truly useful artificial intelligence lets users avoid downloading tons of apps while still getting customized service, information, and companionship via their A.I.s.

Your consumers spend a lot of time exploring and analyzing suitable information―which books to study, which news articles to read, which songs to play, which movies to watch, which games to play, and so on. Imagine, what their experience would be like, if they don't need to pick anything on their own, but are presented with options of their liking―be it in education or media or entertainment. Here are some of the things they can be offered: • Adaptive text-books, in which content changes based on the pace of learning and comfort level of the reader. Such advancements reduce the overall time spent on information discovery, and increase the scope of effective information consumption (or learning). Domains such as education, publishing, entertainment, and advertisement mostly deal with granular digital assets (text, images, audio, video, multi-media, and so on), and are better prepared to enhance personalization even without creating new content from scratch.

In the past years, a collection of hardware, software and online service have managed to bring changes and reforms to classrooms and teaching methods. But the true disruption of education is yet to arrive. Artificial Intelligence has proven its role as a game changing factor in an increasing number of fields, causing transformations unimaginable in the past. It's now showing glimmers of how it might forever change the learning process, one of the oldest skills that mankind has mastered. Gary Vaynerchuk was so impressed with TNW Conference 2016 he paused mid-talk to applaud us.

CyberSaint, Inc. today announced the release of CyberStrong(TM), a breakthrough cybersecurity cloud platform that enables organizations to manage cybersecurity as a measurable and predictable business function. CyberStrong is powered by Amazon Web Services (AWS) Cloud and AWS Artificial Intelligence (AI) services. The new offering is also hosted in the AWS NIST/FISMA regulatory compliant cloud environment. Industry experts predict that CyberStrong will revolutionize the cybersecurity industry. "Today's cybersecurity solutions are mostly disjointed point solutions, which are hard to justify, prioritize, and reconcile with each other," said Massachusetts Institute of Technology (MIT) Research Affiliate and cybersecurity expert Dr. Raphael Yahalom.

The original sample was drawn from two sources. Fifty-one percent of respondents are part of NORC's AmeriSpeak panel, which was selected randomly from NORC's National Frame based on address-based sampling and recruited by mail, email, telephone and face-to-face interviews. Forty-nine percent of respondents are part of a custom panel of young adults that uses an address-based sample from a registered voter database of the entire U.S and is recruited by mail and telephone.
