AI models were better than human experts at predicting the ratings Belgian beers received on a popular review site:

To compare the models, they split the data into a training set and a test set. Once a model was trained on the data within the training set, they evaluated its ability to predict the test set.

The researchers found that all the models were better than the trained panel of human experts at predicting the rating a beer had received from RateBeer.

Through these models, the researchers were able to pinpoint specific compounds that contribute to consumer appreciation of a beer: people were more likely to rate a beer highly if it contained these specific compounds. For example, the models predicted that adding lactic acid, which is present in tart-tasting sour beers, could improve other kinds of beers by making them taste fresher.

"We had the models analyze these beers and then asked them 'How can we make these beers better?'" says Kevin Verstrepen, a professor at KU Leuven and director of the VIB-KU Leuven Center for Microbiology, who worked on the project. "Then we went in and actually made those changes to the beers by adding flavor compounds. And lo and behold—once we did blind tastings, the beers became better, and more generally appreciated."

    I know I'm supposed to be horrified, and maybe part of me is... but mostly I just want to try the best beers that the AI has come up with.

      I wouldn't be horrified if AI could "sudo make me a sandwich". https://xkcd.com/149/ [xkcd.com] Just saying.

    AI Could Make Better Beer. Here’s How.

    Ah... micro-brewed!

    It seems to me that the AI did what it was asked to do.... determine how to increase the ratings for beer, and did so by suggesting the addition of a compound. That's the equivalent of teaching to the test, rather than teaching to produced better educated students. Making actually better beer which happened to contain that compound would have entailed telling the brewmaster how to alter the beer-making process or the mix of ingredients to get that result.

      Tsk. You missed the main point of the study: researchers got a grant to taste Belgian ales for five years.

      Their study results might not amount to much -- I'm fairly sure that wasn't part of the plan anyway -- but I can assure you that, over all that time and on average, they went home in a much better mood than the average employee.

      I can only suggest a pint if you do not realize the utter brilliance of their project.

    Aaaand, we are supposed to be impressed by this? An AI says to add some addictive drug or fake flavoring because its statistical model shows other product's sales increase after adding it. Nobody could have predicted that.

    Right, if something goes wrong then they just blame the the AI sock puppet. Or, if customers come shaking to the door demanding more, then good for profits, and you can thank the magical AI for it all.

    Sadly this is the future.

    I look forward to my future breakfast of healthy, delicious, Sediment Shaped Sediment.

    Microsoft AI comes up with perfect beer, says "Hold my beer", then says "Dear Aunt, let's set so double the killer delete select all"

      I assume the end quote was supposed to be gibberish?

        Nah...it's a quote from Microsoft's Vista speech to text

        During a demonstration of the speech recognition feature new to Windows Vista at Microsoft's Financial Analyst Meeting on July 27, 2006, the software recognized the phrase "Dear mom" as "Dear aunt". After several failed attempts to correct the error, the sentence eventually became "Dear aunt, let's set so double the killer delete select all"

          Nice, I would definitely put that one up there with Bill Gates' "Blue Screen" moment when present Windows 95 to the world.
