Sometimes it’s just great “when a plan comes together.” An avid warbird photographer, I’d been familiar with Christian Kieffer’s outstanding pinup photography for years – his company produces some truly amazing nostalgic calendars featuring vintage WWII aircraft and models done up to mimic the pinups from the same era that helped to keep many an airman’s spirits high. Thinking the subject matter would lend itself well to 3D, I approached Christian a few months ago about...
The 2004 release of id Software’s Doom 3 spurred many PC gamers to upgrade their rigs – with many building completely new machines with the sole intent of driving this game at its ultimate eye-candy settings. And many gamers still came up a bit short, which is just one reason why they are looking forward to jumping into the corridor-crawling fray again with the release of Doom 3 BFG Edition.Silverlight.createObject("http://d2q1944p6r21t1.cloudfront.net/files/...

More people have probably heard of the annual NIPS conference in the past week than over its previous 30 years as the premier event focused on neural networks.

The once obscure gathering — held last week in Long Beach, Calif. — drew coverage from the New York Times, Bloomberg, The Economist and other major outlets, focused on its astounding growth as AI has become a hot field and on the mad dash companies are making to recruit gifted developers.

But recall what put NIPS on the map in the first place: the sharing of world-class research that advances artificial intelligence.

Two of our NVIDIA AI Labs (NVAIL) partners were among those presenting groundbreaking work. Researchers at New York University have advanced how computers can classify objects within complex images, and taken a step toward what might loosely be thought of as peripheral vision for machines.

And researchers at the University of California, Berkeley, are using the parallel processing power of GPUs to give machines more “curiosity” to explore their environments when trying to complete a task.

Giving Image Recognition a Second Look

At NIPS, lead NYU researcher Sean Welleck described how his team is using reinforcement learning to help computers better classify the objects within images.

Instead of looking at an image in a rote pattern — say from left to right, starting at the top and working its way to the bottom — the team’s multi-object recognition model takes a high-level look at all the objects in the image. If it identifies something it can likely classify correctly, then it takes a closer look and gets a reward if it’s right. It then proceeds to another object it has a good bead on.

This ability to classify objects in any order is a major advancement, and could lead to faster and more accurate image classification. It also minimizes the need for annotating objects — the drudgework often required to get good, labeled datasets to work with. Welleck’s work makes the best of the labels already present.

The research is also a step toward giving computers peripheral vision, where two levels of attention — one scanning the image for objects and the other deciding to take a closer look at potentially interesting items — are in play.

Rewarding Complex Tasks

At Berkeley, Justin Fu is lead researcher on work to overcome the problem in reinforcement learning of how to incentivize a machine to complete complex tasks. A classic reward test is the game Pong, where an AI, or even a sophisticated toddler, can learn to manipulate a paddle to successfully keep a ricocheting ball in play.

But games with many more choices, like Doom, pose a much greater challenge for an AI, and plenty of high-IQ humans, because the reward only comes after a much longer sequence of successful steps. If the task is complex enough, the chance of randomly completing it — and ever getting the reward — is slim.

The research team’s proposed solution uses what’s known as an exemplar model. In it, the model is incentivized to take actions that result in unexpected outcomes — so your robot isn’t trying the same left turn every time it sees a T in a maze. Instead, it’s incentivized to explore the options in its environment.

It does this by determining the differences between new images and all the previous ones it’s seen. Instead of comparing raw pixels between images, the model trains a classifier to distinguish what’s new in an image compared to earlier ones it’s examined.

Thanks to GPU computing, the model can crank through tons of images quickly, classifying everything as it goes. Noting these subtle changes to the environment helps the model try new options and better figure out how to successfully complete its task.

NYU and Berkeley are two of the 20 universities across the globe our NVAIL program supports. NVAIL helps researchers from schools like these advance their work through assistance from NVIDIA researchers and engineers, support for the universities’ students, and with access to the industry’s most advanced GPU computing power, like the DGX-1 AI supercomputer.

Artificial intelligence is years, even decades, from replicating functions of the human mind, but it’s still getting serious work done today. And its influence will only expand. The irony of all that promise: Human minds are way behind. Relatively few have a baseline understanding about how AI and deep learning truly work.

Techniques like machine learning, which underpin many of today’s AI tools, aren’t easy to grasp. They feed computers massive volumes of information to “teach” them to recognize our words or halt for a stop sign. This isn’t just dissimilar to how human minds work: it also involves techniques that can’t be understood without an effective teacher.

Best Courses in AI, Deep Learning, and Machine Learning

Luckily, AI’s recent popularity has yielded hundreds of articles, videos, webinars, courses and books catering to beginners and experts who aspire to expand their minds. Below, we’ve curated a selection of the best available.
