"Pick the most unsafe environment", followed by pictures of a house, a park, a volcano, a bed. My sense is that IBM's Watson could tackle this particular question. Also interesting to note that the question introduces external considerations, such as whether or not there's someone dangerous near the house, bed, park, etc. A human respondent will have to ignore the matter of whether there's additional context and seco…

Like Deep Blue, Watson represented a major advance in the state of weak AI. However at its core, it's still just a text-based statistical search engine. It has no ability to "learn" new abilities. Its algorithms will use previous answers to adjust ranking of answers, but once a category is finished, that data is lost. For new data, its database needs to be re-indexed. For new behavior like recognizing pictures or pla…

Yes its interesting; you can easily imagine that the following trends are detected:

* "home and safe" "safe as houses" etc

* "safe in bed" "safely tucked up in bed" etc

* "volcano" ... no clear data. Certainly dangerous being a volcanologist, but that'd be great AI googlefu

* "pensioner attacked in park" .. "our parks are not safe" etc... Hmm, Parks are the most dangerous.

Because frequency of local newspaper reports is a bad measure for volcanos I guess.

Reminds me of a hack day at Yahoo where one team made a captcha where you had to match a photo with its tags and another team made an algorithm that would assign tags to a photo. Both based on Flickr humans meant that the captcha was easily solvable by the algorithm.

He's also one of the few famous entrepreneurs from Guatemala.

That's fantastic. I was trying to guess from the name. Latin American? German? Vietnamese?

Most likely of German descent. I seem to remember when travelling through Guatemala about 10 years ago that one of the locals that I got to know explained that the wealth in Guatemala, especially around Antigua, is concentrated in a number of immigrant families of European (primarily German) descent. There are about 13 large families and they tend to marry within that group.

Google software could use their 99% successful algorithm to filter potential captchas. Then show the 1% they can't crack to humans.

Now the race becomes who can write the better captcha solver, Google or the spammers? As spammers learn to identify things in the 1%, Google will hopefully improve faster and continue to narrow the "hard to solve" band.

>CAPTCHA images correctly solved by the algorithm

well, isnt that great? Because I, HUMAN, can maybe solve _one_ of those (lower right one).

I frickin HATE google Captchas and simply close the page if it wants me to solve one, they are too hard for me.

Does google aggregate&correlate data in vision algo?

For example for street numbers they not only have picture of a number, they also have knowledge of all the other numbers on that street and guesses for those other numbers. Easy to guesstimate order of a number by checking neighbouring ones.

Same for book words, they have n-gram database. http://storage.googleapis.com/books/ngrams/books/datasetsv2....

Thats a lot of useful MAP/ML data.

But the example they give for the new captchas all look like random crap, "mhhfereeeem" and the like. Its like they are not interested in structure, just pure geometry of letters/numbers.
