Drinking Bleach Won’t Cure Cancer or Anything Else, F.D.A. Says
Alarmed about misinformation online, the agency warned about bleach solutions that are being marketed as cures for autism, H.I.V./AIDS and cancer.
Superstition in the Network: Deep Reinforcement Learning Plays Deceptive Games
Deep reinforcement learning has learned to play many games well, but failed
on others. To better characterize the modes and reasons of failure of deep
reinforcement learners, we test the widely used Asynchronous Actor-Critic (A2C)
algorithm on four...
Just say no
“The difference between successful people and very successful people is that very successful people say no to almost everything.” That is Warren Buffett, quoted in Farnam Street. I’m always delighted when something I’ve been doing is vindicated by...

Object Discovery with a Copy-Pasting GAN
We tackle the problem of object discovery, where objects are segmented for a
given input image, and the system is trained without using any direct
supervision whatsoever. A novel copy-pasting GAN framework is proposed, where
the generator learns to...
Judgments of Effort for Magical Violations of Intuitive Physics
People spend much of their time in imaginary worlds, and have beliefs about the events that are likely in those worlds, and the laws that govern them. Such beliefs are likely affected by people’s intuitive theories of the real world. In two...
