DARPA pushes for AI that can explain its decisions

Companies like to flaunt their use of artificial intelligence to the point where it’s virtually meaningless, but the truth is that AI as we know it is still quite dumb. While it can generate useful results, it can’t explain why it produced those results in meaningful terms, or adapt to ever-evolving situations. DARPA thinks it can move AI forward, though. It’s launching an Artificial Intelligence Exploration program that will invest in new AI concepts, including “third wave” AI with contextual adaptation and an ability to explain its decisions in ways that make sense. If it identified a cat, for instance, it could explain that it detected fur, paws and whiskers in a familiar cat shape.

Importantly, DARPA also hopes to step up the pace. It’s promising “streamlined” processes that will lead to projects starting three months after a funding opportunity shows up, with feasibility becoming clear about 18 months after a team wins its contract. You might not have to wait several years or more just to witness an AI breakthrough.

The industry isn’t beholden to DARPA’s schedule, of course. It’s entirely possible that companies will develop third wave AI as quickly on their own terms. This program could light a fire under those companies, mind you. And if nothing else, it suggests that AI pioneers are ready to move beyond today’s ‘basic’ machine learning and closer to AI that actually thinks instead of merely churning out data.

Science Fiction Cities: How our future visions influence the cities we build

For over a century science fiction filmmaking has presented us with depictions of our future cities. Some have been bright, shiny and positive, while others have been dark, dirty and rough. As we look forward to a 21st century filled with massive mega-cities, and extraordinary technological innovation, we must ask how are our science fiction visions influencing the cities we build, and what can we learn from some of these prescient fictional texts?

Uc Berkeley Aging Research And Technology Innovation Summit

August 17th sees our friends at UC Berkeley hosting an aging research summit which is shaping up to be pretty interesting.


Please join us for a day of speakers, awards, poster sessions, and valuable networking focused on cutting-edge aging research and technologies. Our aim is no less than to reimagine aging and elder care. A percentage of the proceeds from this event will support scholarships for students interested in research on aging & elder care…

The tools – and weapons – China can use for tech supremacy

Two weeks ago Abacus examined the extent to which China lags behind the world’s advanced economies in technological innovation, and looked at Beijing’s aim of closing the gap and taking the lead in key emerging technologies.


Some techniques Beijing will use are similar to past episodes of industrial planning. Others are newer, reflecting China’s recently acquired economic strength and confidence.

Science fiction becomes science fact as researchers create liquid metal heartbeat

In a breakthrough discovery, University of Wollongong (UOW) researchers have created a “heartbeat” effect in liquid metal, causing the metal to pulse rhythmically in a manner similar to a beating heart.

Their findings are published in the 11 July issue of Physical Review Letters, the world’s premier journal for fundamental physics research.

The researchers produced the heartbeat by electrochemically stimulating a drop of liquid gallium, causing it to oscillate in a regular and predictable manner. Gallium (Ga) is a soft silvery metal with a low melting point, becoming liquid at temperatures greater than 29.7C.
