One of the biggest mysteries among people working on salmon recovery in Puget Sound and the Salish Sea is what happens to juvenile fish once they head for the ocean. Survival rates of Chinook, Coho and Steelhead have all declined since the 1980s, but resource managers don’t know why.

A new grant from Microsoft is using artificial intelligence to greatly improve the computer models used to tackle the question.

When You're Not Quite Sure If Your Teacher Is Human

May 8, 2017

A couple of years ago, Ashok Goel was overwhelmed by the number of questions his students were asking in his course on artificial intelligence.

Goel teaches computer science at Georgia Tech, sometimes to large classes, where students can ask thousands of questions online in a discussion forum.

With a limited number of teaching assistants, or TAs, many of those questions weren't getting answered in time. So, Goel came up with a plan: make an artificial intelligence "teaching assistant" that could answer some of students' frequently asked questions.

The terms of the next loan you get might depend less on your credit score and more on what a computer program thinks of your habits.

Digital lending is expected to double in size over the next three years, reaching nearly 10 percent of all loans in the U.S. and Europe. There are now some 2,000 digital startups, many of which are using artificial intelligence to analyze the troves of data created every day.

But government regulators are struggling to keep up with the pace of change.

At a luncheon hosted by the Technology Alliance in Seattle, Microsoft Chief Executive Satya Nadella weighed in on whether computers will one day put a lot of us out of work, and his take is that people are right to be concerned.

An artificially intelligent computer system built by Google has just beaten the world's best human, Lee Sedol of South Korea, at an ancient strategy game called Go. Go originated in Asia about 2,500 years ago and is considered many, many times more complex than chess, which fell to AI back in 1997.

The five-game clash pitting man against machine is over, with Google's artificial intelligence program winning the series.The program — called AlphaGo — took four of five games against Korean Lee Sedol, an 18-time world champion of the board game Go.

"I feel a little regrettable because I believe that there is more that a human being could have shown in a match against artificial intelligence," Lee said following the final match.

In the first of a series of games pitting Google's AI computer against a human world champion in the ancient game of Go, Google DeepMind's AlphaGo program has narrowly taken Round 1 from Lee Sedol.
