Researchers at Parc, a laboratory with links to some of Silicon Valley’s biggest breakthroughs, have just taken on a particularly thorny challenge: teaching intelligent machines to explain, in human terms, how their minds work.
The project, one of several sponsored by the US Defense Advanced Research Projects Agency (Darpa), is part of the search for an answer to one of the hardest problems in artificial intelligence.
Deep learning systems, the most advanced form of machine learning that is at the heart of recent breakthroughs in AI, have shown they can match humans in recognising images or driving a car. But even the experts cannot tell exactly why they come up with the answers they do.
