To maintain and build a Hi-tech military advantage, the Pentagon is turning to the country's software and technology hub, Silicon Valley and its hottest and latest technology Artificial Intelligence, popularly known as AI. Today, Ash Carter, Secretary of Defense made his fourth trip to the area since his appointment on the post in last year. He had been the frequent traveler of the region in the past as well, he said in his speech given at the Defense Department Research Facility near Google's headquarters. US, currently, is concerned with the re-emergence of China and Russia in the military powers and therefore is looking a unique and a better tool to make the military of the country strong and rigid. This plan was articulated as "Third offset" strategy by Carter at last fall.

The US military is at the forefront of futuristic tech from lasers on aircraft to stealth jets and now it has been showing off its developments designed to help its soldiers and patients. At a science fair-style event at The Pentagon, the 3 billion agency has demoed its advanced prosthetic arms able to restore the sense of touch and feel to amputees. It also showcased implants that can help restore the memory of people suffering brain injuries or in people with post traumatic stress disorder. At a science fair-style event at The Pentagon, Darpa has demoed prosthetic arms able to restore the sense of touch and feel to amputees. One of the amputees at the event was Johnny Matheny.

A SpaceX capsule returned to Earth on Wednesday with precious science samples from NASA's one-year space station resident. SpaceX reported a good splashdown, with three red-and-white striped parachutes slowing the final descent. The Dragon had been at the station for a month, dropping off supplies as well as an experimental, inflatable room that will pop open in two weeks. It was set free by the station's big robot arm. "Dragon spacecraft has served us well, and it's good to see it departing full of science," Peake radioed from 250 miles up.

One day in January, Eric Wilson dashed off a message to the teaching assistants for an online course at the Georgia Institute of Technology. "I really feel like I missed the mark in giving the correct amount of feedback," he wrote, pleading to revise an assignment. Thirteen minutes later, the TA responded. "Unfortunately, there is not a way to edit submitted feedback," wrote Jill Watson, one of nine assistants for the 300-plus students. Last week, Mr. Wilson found out he had been seeking guidance from a computer.

Maitreya One, a black futurist and hip-hop artist living in Harlem, steps off the Greyhound bus on a warm morning in Montgomery, Alabama. I walk up to him and give him a hug. Nightmare scenarios involving Artificial Intelligence typically involve computers that become too smart for their own good and turn against their creators. In 2001: A Space Odyssey, HAL 9000 famously refused to open the pod bay doors for Dave: Well, now we have an entirely different cause to be wary of AI, and the culprit is human rather than machine.

Motivated by applications in recommender systems, web search, social choice and crowdsourcing, we consider the problem of identifying the set of top $K$ items from noisy pairwise comparisons. In our setting, we are non-actively given $r$ pairwise comparisons between each pair of $n$ items, where each comparison has noise constrained by a very general noise model called the strong stochastic transitivity (SST) model. We analyze the competitive ratio of algorithms for the top-$K$ problem. In particular, we present a linear time algorithm for the top-$K$ problem which has a competitive ratio of $\tilde{O}(\sqrt{n})$; i.e. to solve any instance of top-$K$, our algorithm needs at most $\tilde{O}(\sqrt{n})$ times as many samples needed as the best possible algorithm for that instance (in contrast, all previous known algorithms for the top-$K$ problem have competitive ratios of $\tilde{\Omega}(n)$ or worse). We further show that this is tight: any algorithm for the top-$K$ problem has competitive ratio at least $\tilde{\Omega}(\sqrt{n})$.

Most existing learning to hash methods assume that there are sufficient data, either labeled or unlabeled, on the domain of interest (i.e., the target domain) for training. However, this assumption cannot be satisfied in some real-world applications. To address this data sparsity issue in hashing, inspired by transfer learning, we propose a new framework named Transfer Hashing with Privileged Information (THPI). Specifically, we extend the standard learning to hash method, Iterative Quantization (ITQ), in a transfer learning manner, namely ITQ+. In ITQ+, a new slack function is learned from auxiliary data to approximate the quantization error in ITQ. We developed an alternating optimization approach to solve the resultant optimization problem for ITQ+. We further extend ITQ+ to LapITQ+ by utilizing the geometry structure among the auxiliary data for learning more precise binary codes in the target domain. Extensive experiments on several benchmark datasets verify the effectiveness of our proposed approaches through comparisons with several state-of-the-art baselines.

Cross-domain visual data matching is one of the fundamental problems in many real-world vision tasks, e.g., matching persons across ID photos and surveillance videos. Conventional approaches to this problem usually involves two steps: i) projecting samples from different domains into a common space, and ii) computing (dis-)similarity in this space based on a certain distance. In this paper, we present a novel pairwise similarity measure that advances existing models by i) expanding traditional linear projections into affine transformations and ii) fusing affine Mahalanobis distance and Cosine similarity by a data-driven combination. Moreover, we unify our similarity measure with feature representation learning via deep convolutional neural networks. Specifically, we incorporate the similarity measure matrix into the deep architecture, enabling an end-to-end way of model optimization. We extensively evaluate our generalized similarity model in several challenging cross-domain matching tasks: person re-identification under different views and face verification over different modalities (i.e., faces from still images and videos, older and younger faces, and sketch and photo portraits). The experimental results demonstrate superior performance of our model over other state-of-the-art methods.

Scientists at Los Alamos National Laboratory and the State Key Laboratory for Mechanical Behavior of Materials in China have used a combination of machine learning, supercomputers, and experiments to speed up discovery of new materials with desired properties. The idea is to replace traditional trial-and-error materials research, which is guided only by intuition (and errors). With increasing chemical complexity, the possible combinations have become too large for those trial-and-error approaches to be practical. The scientists focused their initial research on improving nickel-titanium (nitinol) shape-memory alloys (materials that can recover their original shape at a specific temperature after being bent). But the strategy can be used for any materials class (polymers, ceramics, or nanomaterials) or target properties (e.g., dielectric response, piezoelectric coefficients, and band gaps).
