The “Black Mirror” scenarios that are leading some experts to call for more secrecy on AI – MIT Technology Review

a new report by more than 20 researchers from the Universities of Oxford and Cambridge, OpenAI, and the Electronic Frontier Foundation warns that the same technology creates new opportunities for criminals, political operatives, and oppressive governments—so much so that some AI research may need to be kept secret. Included in the report, The Malicious Use […]

IBM Watson to generate sales solutions

“We’ve trained Watson on our standard solutions and offerings, plus all the prior solutions IBM has designed for large enterprises,” the corporate files state. “This means we can review a client’s RFP [request for proposal] and come up with a new proposed architecture and technical solution design for a state of the art system that […]

Missing data hinder replication of artificial intelligence studies

Last year, computer scientists at the University of Montreal (U of M) in Canada were eager to show off a new speech recognition algorithm, and they wanted to compare it to a benchmark, an algorithm from a well-known scientist. The only problem: The benchmark’s source code wasn’t published. The researchers had to recreate it from […]

New AI model fills in blank spots in photos

The technology was developed by a team led by Hiroshi Ishikawa, a professor at Japan’s Waseda University. It uses convolutional neural networks, a type of deep learning, to predict missing parts of images. The technology could be used in photo-editing apps. It can also be used to generate 3-D images from real 2-D images. The […]

Moth brain uploaded to computer, taught to recognise numbers

MothNet’s computer code, according to the boffins, contains layers of artificial neurons to simulate the bug’s antenna lobe and mushroom body, which are common parts of insect brains. Crucially, instead of recognizing smells, the duo taught MothNet to identify handwritten digits in the MNIST dataset. This database is often used to train and test pattern […]

Look out, Wiki-geeks. Now Google trains AI to write Wikipedia articles

A paper, out last month and just accepted for this year’s International Conference on Learning Representations (ICLR) in April, describes just how difficult text summarization really is. A few companies have had a crack at it. Salesforce trained a recurrent neural network with reinforcement learning to take information and retell it in a nutshell, and […]

Gfycat Uses Artificial Intelligence to Fight Deepfakes Porn

Gfycat says it’s figured out a way to train an artificial intelligence to spot fraudulent videos. The technology builds on a number of tools Gfycat already used to index the GIFs on its platform. [..] Gfycat’s AI approach leverages two tools it already developed, both (of course) named after felines: Project Angora and Project Maru. […]

Facial Recognition Is Accurate, if You’re a White Guy

Facial recognition technology is improving by leaps and bounds. Some commercial software can now tell the gender of a person in a photograph. When the person in the photo is a white man, the software is right 99 percent of the time. But the darker the skin, the more errors arise — up to nearly […]

Worm brain translated into a computer is taught tricks without programming

It is not much to look at: the nematode C. elegans is about one millimetre in length and is a very simple organism. But for science, it is extremely interesting. C. elegans is the only living being whose neural system has been analysed completely. It can be drawn as a circuit diagram or reproduced by […]

Robot learns to mimic simple human motions

Researchers from the University of California, Berkeley, in the USA, have made some progress on this front by teaching code controlling a robot arm and hand to perform three tasks: grabbing an object and placing it in a specific position; pushing an object; and pushing and pulling an object after seeing the same action performed […]

Engineers design artificial synapse for “brain-on-a-chip” hardware

engineers at MIT have designed an artificial synapse in such a way that they can precisely control the strength of an electric current flowing across it, similar to the way ions flow between neurons. The team has built a small chip with artificial synapses, made from silicon germanium. In simulations, the researchers found that the […]

Revealing True Emotions Through Micro-Expressions: A Machine Learning Approach

Micro-expressions–involuntary, fleeting facial movements that reveal true emotions–hold valuable information for scenarios ranging from security interviews and interrogations to media analysis. They occur on various regions of the face, last only a fraction of a second, and are universal across cultures. In contrast to macro-expressions like big smiles and frowns, micro-expressions are extremely subtle and […]

Facebook open sources Detectron, object detection framework in caffe2

Today, Facebook AI Research (FAIR) open sourced Detectron — our state-of-the-art platform for object detection research. The Detectron project was started in July 2016 with the goal of creating a fast and flexible object detection system built on Caffe2, which was then in early alpha development. Over the last year and a half, the codebase […]

Active learning machine learns to create new quantum experiments

We present an autonomous learning model which learns to design such complex experiments, without relying on previous knowledge or often flawed intuition. Our system not only learns how to design desired experiments more efficiently than the best previous approaches, but in the process also discovers nontrivial experimental techniques. Our work demonstrates that learning machines can […]

New AI System Predicts How Long Patients Will Live With Startling Accuracy

By using an artificially intelligent algorithm to predict patient mortality, a research team from Stanford University is hoping to improve the timing of end-of-life care for critically ill patients. After parsing through 2 million records, the researchers identified 200,000 patients suitable for the project. The researchers were “agnostic” to disease type, disease stage, severity of […]

When It Comes to Gorillas, Google Photos Remains Blind – it’s hard to take an AI to account

In a third test attempting to assess Google Photos’ view of people, WIRED also uploaded a collection of more than 10,000 images used in facial-recognition research. The search term “African american” turned up only an image of grazing antelope. Typing “black man,” “black woman,” or “black person,” caused Google’s system to return black-and-white images of […]

Boffins tweak audio by 0.1% to fool speech recognition engines

a paper by Nicholas Carlini and David Wagner of the University of California Berkeley has explained off a technique to trick speech recognition by changing the source waveform by 0.1 per cent. The pair wrote at arXiv that their attack achieved a first: not merely an attack that made a speech recognition SR engine fail, […]

This Ex-NSA Hacker Is Building an AI to Find Hate Symbols on Twitter

NEMESIS, according to Crose, can help spot symbols that have been co-opted by hate groups to signal to each other in plain sight. At a glance, the way NEMESIS works is relatively simple. There’s an “inference graph,” which is a mathematical representation of trained images, classified as Nazi or white supremacist symbols. This inference graph […]

AI System Sorts News Articles By Whether or Not They Contain Actual Information

In a recent paper published in the Journal of Artificial Intelligence Research, computer scientists Ani Nenkova and Yinfei Yang, of Google and the University of Pennsylvania, respectively, describe a new machine learning approach to classifying written journalism according to a formalized idea of “content density.” With an average accuracy of around 80 percent, their system […]

Google’s voice-generating AI is now indistinguishable from humans

A research paper published by Google this month—which has not been peer reviewed—details a text-to-speech system called Tacotron 2, which claims near-human accuracy at imitating audio of a person speaking from text. The system is Google’s second official generation of the technology, which consists of two deep neural networks. The first network translates the text […]

Project Maven brings AI to the fight against ISIS

For years, the Defense Department’s most senior leadership has lamented the fact that US military and spy agencies, where artificial intelligence (AI) technology is concerned, lag far behind state-of-the-art commercial technology. Though US companies and universities lead the world in advanced AI research and commercialization, the US military still performs many activities in a style […]
