AI edges closer to understanding 3D space the way we do

If I show you a single picture of a room, you can tell me right away that there’s a table with a chair in front of it, they’re probably about the same size, about this far from each other, with the walls this far away — enough to draw a rough map of the room. Computer vision systems don’t have this intuitive understanding of space, but the latest research from DeepMind brings them closer than ever before.

The new paper from the Google -owned research outfit was published today in the journal Science (complete with news item). It details a system whereby a neural network, knowing practically nothing, can look at one or two static 2D images of a scene and reconstruct a reasonably accurate 3D representation of it. We’re not talking about going from snapshots to full 3D images (Facebook’s working on that) but rather replicating the intuitive and space-conscious way that all humans view and analyze the world.

When I say it knows practically nothing, I don’t mean it’s just some standard machine learning system. But most computer vision algorithms work via what’s called supervised learning, in which they ingest a great deal of data that’s been labeled by humans with the correct answers — for example, images with everything in them outlined and named.

This new system, on the other hand, has no such knowledge to draw on. It works entirely independently of any ideas of how to see the world as we do, like how objects’ colors change toward their edges, how they get bigger and smaller as their distance changes and so on.

It works, roughly speaking, like this. One half of the system is its “representation” part, which can observe a given 3D scene from some angle, encoding it in a complex mathematical form called a vector. Then there’s the “generative” part, which, based only on the vectors created earlier, predicts what a different part of the scene would look like.

(A video showing a bit more of how this works is available here.)

Think of it like someone handing you a couple of pictures of a room, then asking you to draw what you’d see if you were standing in a specific spot in it. Again, this is simple enough for us, but computers have no natural ability to do it; their sense of sight, if we can call it that, is extremely rudimentary and literal, and of course machines lack imagination.

Yet there are few better words that describe the ability to say what’s behind something when you can’t see it.

“It was not at all clear that a neural network could ever learn to create images in such a precise and controlled manner,” said lead author of the paper, Ali Eslami, in a release accompanying the paper. “However we found that sufficiently deep networks can learn about perspective, occlusion and lighting, without any human engineering. This was a super surprising finding.”

It also allows the system to accurately recreate a 3D object from a single viewpoint, such as the blocks shown here:

I’m not sure I could do that.

Obviously there’s nothing in any single observation to tell the system that some part of the blocks extends forever away from the camera. But it creates a plausible version of the block structure regardless that is accurate in every way. Adding one or two more observations requires the system to rectify multiple views, but results in an even better representation.

This kind of ability is critical for robots, especially because they have to navigate the real world by sensing it and reacting to what they see. With limited information, such as some important clue that’s temporarily hidden from view, they can freeze up or make illogical choices. But with something like this in their robotic brains, they could make reasonable assumptions about, say, the layout of a room without having to ground-truth every inch.

“Although we need more data and faster hardware before we can deploy this new type of system in the real world,” Eslami said, “it takes us one step closer to understanding how we may build agents that learn by themselves.”

Facebook’s longtime head of policy and comms steps down

A prominent figure that helped shape Facebook public perception over the course of the last decade is on the way out. In a Facebook post today, Elliot Schrage, vice president of communications and public policy, announced his departure.

Schrage joined the company in 2008 after leaving his position in the same role at Google. He had come under fire over the last year at Facebook for his influence in shaping Facebook’s highly criticized public reaction to a series of scandals that began with the platform’s policies during the 2016 U.S. presidential election. In response to questions about Facebook’s potential unwitting role in influencing the outcome of the election, Mark Zuckerberg famously dismissed such concerns as a “pretty crazy idea.”

In a Facebook post, Schrage elaborates:

After more than a decade at Facebook, I’ve decided it’s time to start a new chapter in my life. Leading policy and communications for hyper growth technology companies is a joy — but it’s also intense and leaves little room for much else. Mark, Sheryl and I have been discussing this for a while. I’ll lead the search to identify someone new to oversee our communications and policy teams. We expect to find someone with the same passion, integrity, determination and energy that our teams bring to Facebook every day. Mark and Sheryl have asked me to stay to manage the transition and then to stay on as an advisor to help on particular projects – and I’m happy to help.

Earlier this week, Schrage reportedly apologized for comments made in response to questions from Arjuna Capital Managing Partner Natasha Lamb during an investor meeting. Lamb inquired about Facebook’s plans to correct its gender pay gap among other uncomfortable lines of questioning for the company. Schrage reportedly told Lamb that the company would not answer her questions because she was “not nice.” It’s not clear if that event influenced the timing of Schrage’s departure.

Developers, hack your way to free passes to Disrupt SF 2018

You’ve heard how TechCrunch Disrupt San Francisco 2018 is going to be the biggest, most ambitious Disrupt ever — and we’re serious. So serious, in fact, that we’re super-sizing the Hackathon, taking it online and making it global. Thousands of the world’s most talented developers, programmers, hackers and tech makers can participate and submit their hacks from anywhere in the world. The clock starts now — you have a little less than 6 weeks to build your team and start creating your projects — so sign up today to get started.

We’re asking you to show us how you’d creatively produce and apply technology to solve various challenges. Judges will review all eligible submitted hacks and rate them on a scale of 1-5 based on the quality of the idea, technical implementation of the idea and the product’s potential impact. The 100 top-scoring teams will receive up to 5 Innovator Passes for their team to attend TechCrunch Disrupt SF 2018.

Plus, the 30 highest-scoring teams will advance to the semi-finals, where they get to demo their newly created product at Disrupt SF. From there, we’ll choose 10 of those teams to pitch their hack on The Next Stage in front of thousands of Disrupt SF attendees. One of those 10 teams will win the $10,000 grand prize and be the first-ever TechCrunch Disrupt Virtual Hackathon champ.

But that’s not all! We’ll also have some fantastic sponsor contests already announced from BYTON, TomTom and Viond:

What can AI do for you while on the move?

What will people want to do in a car that has a 49” screen and drives autonomously? How can we create an enjoyable time with a vehicle that’s able to communicate with other vehicles on the road or smart city infrastructure? We challenge you to think creatively and develop unique solutions to give people their “time to be” while on the move. Smart agendas, recommendations and digital assistants are only some of the ways we’re thinking about doing artificial intelligence during the age of autonomy.

At BYTON we define ourselves by giving customers their “time to be” while in our cars through a unique user experience, interior design, and autonomous driving. The BYTON Concept is designed to make technology benefit life, providing an enjoyable time for people on the move. BYTON Life is the core of that experience. It is an open digital cloud platform that connects applications, data and smart devices. When integrated with innovative human-vehicle interaction, it takes the intelligent experience with the vehicle to a whole new level.

Sponsor Prizes: $5,000 and an invitation to a BYTON Co-creation Event to meet the creators of BYTON Life will be awarded to the top team that utilizes existing technology and APIs of their choice to develop a unique and creative solution. Awards for second prize will be $2,000 and third prize will be $1,000.
