Teaching robots what humans want

Told to optimize for speed while racing down a track in a computer game, a car pushes the pedal to the metal … and proceeds to spin in a tight little circle. Nothing in the instructions told the car to drive straight, and ...

Predator and prey in cyber stasis

In the world of cybersecurity, just as in nature, there are predators and there is prey. The predators are the hunters, the ones that seek out the weak and the vulnerable on which to prey, that applies whether we are talking ...

Researchers reverse the flow of time on IBM's quantum computer

We all mark days with clocks and calendars, but perhaps no timepiece is more immediate than a mirror. The changes we notice over the years vividly illustrate science's "arrow of time"—the likely progression from order to ...

Research identifies key weakness in modern computer vision systems

Computer vision algorithms have come a long way in the past decade. They've been shown to be as good or better than people at tasks like categorizing dog or cat breeds, and they have the remarkable ability to identify specific ...
