AI extracts speech bubbles from comic strips

Segmentation — partitioning an image or scan into multiple segments, or sets of pixels — is a task at which artificial intelligence (AI) excels. Case in point: Researchers at Google parent company Alphabet’s DeepMind recently revealed in an academic paper that they’d developed a system capable of segmenting CT scans […]

Google AI technique reduces speech recognition errors by 29%

Speech recognition is pretty darn good these days. State-of-the-art models like EdgeSpeechNet, which was detailed in a research paper late last year, are capable of achieving about 97 percent accuracy. But even the best systems sometimes stumble on uncommon and rare words. To narrow the gap, scientists at Google and […]

Vivo V15 Pro review: 48 megapixels makes a difference

A little over a year ago, Dongguang, China-based electronics giant Vivo debuted the Vivo Nex S, a nearly bezeless smartphone that tweaked the conventional candy bar formula in two important ways: With a front-facing camera that elevated from a flush compartment, and with a fingerprint scanner embedded beneath display glass. Neither was […]

OpenAI: Social science, not just computer science, is critical for AI

AI safety research needs social scientists to ensure AI succeeds when humans are involved. That’s the crux of the argument advanced in a new paper published by researchers at OpenAI (“AI Safety Needs Social Scientists“), a San Francisco-based nonprofit backed by tech luminaries Reid Hoffman and Peter Thiel. “Most AI […]

AI predicts smartphone transportation modality from Wi-Fi signals

You can learn a lot about people from the gadgets on their person, history has taught us, and that includes their movements. In a paper published on the preprint server Arxiv.org (“A Semi-Supervised Deep Residual Network for Mode Detection in Wi-Fi Signals“), researchers at Ryerson University in Toronto, Canada describe […]

AI detects potentially damaging ice on wind turbines

Ice is the enemy of turbines everywhere. Some wind farms report energy production losses of up to 20 percent due to icing, according to Canadian wind-industry consultancy firm TechnoCentre Éolien (TCE), and that’s not the worst of it. Over time, ice shedding from blades can damage other blades or overstress internal […]

Researchers, scared by their own work, hold back “deepfakes for text” AI

Enlarge / This is fine. reader comments 30 with 28 posters participating Share this story OpenAI, a non-profit research company investigating “the path to safe artificial intelligence,” has developed a machine learning system called Generative Pre-trained Transformer-2 (GPT-2 ), capable of generating text based on brief writing prompts. The result comes so close to mimicking […]

AI Weekly: Trump’s American AI Initiative lacks substance

It’s been an eventful week in tech. Amazon announced it would abandon plans to open one of its two HQ2 locations in New York City, and the company also acquired Wi-Fi mesh network startup Eero for an undisclosed sum — a hint at Amazon’s future smart home ambitions. The California […]

Google open-sources PlaNet, an AI agent that learns about the world from images

Reinforcement learning — a machine learning training technique that uses rewards to drive AI agents toward certain goals — is a reliable means of improving said agents’ decision-making, given plenty of compute, data, and time. But it’s not always practical; model-free approaches, which aim to get agents to directly predict actions […]

Researchers improve robots’ speech recognition by modeling human auditory processing

We rarely think too much about noises as we’re listening to them, but there’s an enormous amount of complexity involved in isolating audio from places like crowded city squares and busy department stores. In the lower levels of our auditory pathways, we segregate individual sources from backgrounds, localize them in space, […]

Machine love: 4 ways AI is helping humans on Valentine’s Day

It’s Valentine’s Day — the holiday on which couples profess their love for one another by gifting chocolates and roses, sharing candlelit meals, and basking together in the glow of a fire (or television). If you’re hitched and somehow procrastinated until now, not to worry — fortunately, artificial intelligence (AI) […]

OpenAI let us try its state-of-the-art NLP text generator

Language is power, and engineering a system that can comprehend it as well as any human is a grand challenge in AI research. Recent contributions like Google’s BERT, a framework that can train state-of-the-art natural language processing (NLP) models in a few hours on a single graphics card, and Facebook’s […]

Beyond GIGO: how “predictive policing” launders racism, corruption and bias to make them seem empirical

“Predictive policing” is the idea that you can feed crime stats to a machine-learning system and it will produce a model that can predict crime. It is garbage. It’s garbage for a lot of reasons. For one thing, you only find crime where you look for it: so if you send out the […]
