We use language to communicate everyday rules and common sense bits of wisdom to others. “If you keep your key in the ignition with the radio blaring but the engine off for 2 hours, your car battery will probably be dead.” Or “Don’t touch the stovetop if the red light is still on.”
In addition to this simple IF-THEN logic, it’s also possible to communicate more complex LOOPs and variable assignments using words. …
Recently, I heard a loud crash in my backyard. As I rushed outside, I found a strange oblong and metallic craft, damaged and half-buried in a muddy crater, a gaping hole ripped in its side. When I peered cautiously inside, I discovered a shaken but unharmed alien staring back at me, its quivering gelatinous brain illuminated by billions of blinking lights, resembling a miniature data center.
“Are you OK?” I yelled.
The alien said nothing. Instead, a series of words flickered on a monitor attached to its chest:
EVENT E1 OCCURRED NOW AT UNKNOWN LOCATION L1
ANIMATE-OBJECT SELF S1 AT E1
How to progress toward Artificial General Intelligence (AGI)
What’s wrong with AI?
If you want to know what’s wrong with current theories of artificial intelligence (AI) — and avoid the next AI winter —just ask a neuroscientist.
In “How We Learn,” neuroscientist Stanislas Dehaene outlines how babies apply a rich assortment of prior models to understand people, objects, time, space and causality. Babies don’t use anything remotely like current AI techniques, except perhaps in the pattern recognition capacity of the senses.
Today’s AI neural networks are shallow and imperfect. They attempt to learn everything at the same level, gleaning superficial statistical regularities in data and shallow features in…
Scientists have discovered that an asteroid 230 million miles from Earth called “16 Psyche” appears to be 90% metallic, composed of nickel and iron. NASA has plans to visit the 120-mile-wide asteroid in 2026.
Psyche is large for an asteroid, but smaller than a planet. So small, in fact, that its surface gravity is only 0.015 times that of Earth. If you were to race across the surface of Psyche at 409 miles per hour, you’d achieve escape velocity and lift off into space.
The value of the metal in the asteroid is estimated at $10,000 quadrillion. That’s a lot…
At a minimum, Artificial General Intelligence (AGI) should explain how common human cognitive tasks are accomplished:
A graph is a handy way to enable these cognitive abilities and represent the state of the environment (observable world). For example, we might recognize a dog as a specific instance of a prototypical dog. …
Elon Musk famously warned that “with artificial intelligence (AI), we are summoning the demon.” He feared that AI might suddenly spin out of control and put society at risk. Ironically, AI must succeed if Musk is to deliver on his promise of self-driving autonomous cars that can navigate through bad weather, poorly marked roads, and novel emergency situations.
In the past two decades, AI has made great strides. Computers can now handily beat human chess masters, as well as world champions at the ancient game of Go. Two AI methods in particular — reinforcement learning (RL) and agent-based modeling (ABM)…
