A.I. accurately predicted the full baseball post-season back in July

- vecter 10y agoHi and welcome to Hacker News! Please only post comments that add something meaningful to the topic of discussion (a proclaimed artificial intelligence that claims to have predicted this result much earlier).
- Tangokat 10y agoNot to be overly critical but: It does not match my definition of A.I: "UNU enables groups of online users to think together as a unified emergent intelligence -- a "brain of brains" that can express itself as a singular entity. Touted to as the world's first "hive mind," the UNU platform has had over 60,000 human participants in swarming sessions this year, together answering over 250,000 questions." Also I would reasonably expect some of those 250.000 questions to beat the odds and get answered right.
- Cortexia 10y agoExcept this was a prediction that was done formally for the Boston Globe, at their request. You can see their article about it here: https://www.bostonglobe.com/sports/redsox/2016/10/04/group-globe-readers-predicted-nine-mlbs-playoff-teams/Fssfk351Wgy3xhRBXkg2CJ/story.html https://www.bostonglobe.com/sports/redsox/2016/10/04/group-g...
- 1024core 10y agoStill, this is not "AI" in the traditional sense of the phrase. Asking a bunch of humans and then deciding an outcome is not AI.
- amperexorange 10y agoWell, I think it's pretty clearly an "emergent intelligence" that is distinct from any of the individuals' unique intelligence. In other words, whose intelligence is being represented by the swarm?
- psyc 10y agoCorporations have been collectively intelligent for centuries, but we don't call that AI.
- AnimalMuppet 10y ago"Wisdom of crowds" might be the correct term.
- no_protocol 10y agoNothing about this seems to add up. They claim they made the prediction in early July, but link to a newspaper article dated 4 August that indicates the predictions were made just one day earlier. They picked the team with the best record all season long to win the championship. They got one of the division winners wrong. Just publishing the current favorites from MLB.com's probability page [0] as of 3 August would have also gotten 9 of 10 postseason teams correct, including going 6/6 on division winners. So the 'knowledge' of fans voting actually did worse than a monte carlo simulation. I'm not impressed. There's no way this should be considered predicting the "full baseball post-season," and I am not seeing any evidence that it happened in July. Wish they'd have shared it.

- fleitz 10y agoThere's also the issue of the full suite of predictions, if these were the only predictions made then it's impressive, but if they made lots of predictions then some of their predictions coming true may be no better than chance.
- Cortexia 10y agoThey also predicted which managers would win the MVP awards, and which players would win the CY YOUNG awards but those don't get announced for 2 weeks.
- hvs 10y agoManagers don't win MVP awards.
- FonzieBear 10y agoWell, The Boston Globe only made the one set of predictions.
- Cortexia 10y agoThey tend to publish academic papers about the predictions. This one is obviously too recent to review, but here is an academic paper (IEEE) about their SUPERBOWL PREDICTIONS, complete with formal statistics: http://unu.ai/wp-content/uploads/2016/10/Crowds-Vs-Swarms-SHBI2016-Final-PDF-confirmed-by-IEEE.pdf http://unu.ai/wp-content/uploads/2016/10/Crowds-Vs-Swarms-SH...
- Cortexia 10y agoHere is the latest UNU election pick: http://unu.ai/election-fatigue/ http://unu.ai/election-fatigue/
- llamataboot 10y agoUNU seems to get their press releases on here a lot. As far as I can see there's not much "AI" involved, just a UI over the "wisdom of crowds" method of making predictions. In this case, the Cubs were heavily favored all season to win the World Series, had arguably one of the best GMs and managers in baseball, and a raft of all-star players. Goat aside, it was fairly smart money to lean towards them from mid-season on. Same thing with their Kentucky Derby prediction this year. The swarm literally decided the horses in the exact odds they were going off at (which makes sense since gambling odds by their very nature are "the wisdom of the crowd") and that's how they finished.
- wrsh07 10y agoAgreed - predicting that the Cubs would win the world series isn't impressive - the majority of SI writers [4/7] did that at the beginning of the season: http://www.si.com/mlb/2016/03/31/playoff-picks-awards-picks-mvp-cy-young-rookie-of-the-year http://www.si.com/mlb/2016/03/31/playoff-picks-awards-picks-... Correctly predicting who would advance in the post season is mostly luck.
- Xeroday 10y agoHas Unu made any incorrect predictions? Their blog only seems to cover the big, successful ones.
- Cortexia 10y agoIn response to such skepticism, reporters come up with their own questions and ask UNU to make predictions. And the reporters monitor the process. That's what this set of picks is - it was done for the BOSTON GLOBE, at their request, with their own participants: https://www.bostonglobe.com/sports/redsox/2016/10/04/group-globe-readers-predicted-nine-mlbs-playoff-teams/Fssfk351Wgy3xhRBXkg2CJ/story.html https://www.bostonglobe.com/sports/redsox/2016/10/04/group-g...
- macintux 10y agoThat doesn't actually answer the question.
- bluetwo 10y agoThis reminds me very much of delta polling, where you survey experts in a field with a complex and unsolvable question, tally the results, send that information back to the experts, and then ask them again. After a few rounds this tends to arrive at what is usually a pretty solid answer. It is used sometimes in scientific and medical research. An automated tool is pretty neat, but like others said, it doesn't really classify as AI. I'm not sure how much money I would really put down on the bets the site makes, but it is similar in some ways to the scandal that rocked Draft Kings/Fan Duel, where admins were using high-level data to make bets on opposing systems. They did in fact make money.
- macawfish 10y agoIt irritates me that this is called "A.I".
- sixhobbits 10y agoThis reminds me of one of the chapters from "How Not to Be Wrong: The Power of Mathematical Thinking" by Jordan Ellenberg (highly recommended). He describes how "stock brokers" would send out a "free stock prediction" to thousands of email addresses. The prediction would be a simple up/down prediction for a specific stock. The prediction was randomly chosen. But these "brokers" would send an equal number of up and down predictions, ensuring that they got a correct prediction for half of their recipients. They would then throw away half of the emails (the wrong half), and repeat with the remaining half. After ten predictions, there would still be a small number of people remaining for whom they'd sent only correct predictions to (10 in a row, which seems really impressive if you can't see the full picture). They would then contact these few people and offer to keep selling them predictions for a fee. Stories like this (And Paul the Octopus, who I see was mentioned already) are exactly the same thing. Thousands of people are trying to using deep learning (i.e. stats), or other crazy methods as in this article, to make predictions. Of course every now and then one of them is going to work better than expected. This would be the case even if people were simply using random numbers. But we ignore all the ones that fail and give heaps of attention to the Pauls.

That's pretty different than sending out thousands of random predictions. This was ONE prediction about MLB.
- vannevar 10y agoBut we don't know how many other predictions were also formally done, by other entities. We're only hearing about this one because it was right.

- losteverything 10y agoAnyone remember Tamara Rand. [0] Well, one of the greatest Tamara Rand jokes was from CNN sports tonight: "The Cubs are predicted to win the World Series. Only thing is it was predicted by Tamara Rand." Quite cool at a time when tv commentary was never light hearted.

- pgodzin 10y agoThe article mentions "swarm intelligence" that essentially forms a hive-mind. Where is the AI/ML when it seems like it just picks the most popular responses from its many respondents?
- lawnchair_larry 10y agoSurvivorship bias. Also why the stated historical performance for your 401k funds are probably tricking you.
- orasis 10y agoOh cool. How many AIs did they have doing the predictions? Survivorship bias.
- andrewclunn 10y agoHow many AIs screwed it up? Remember the hits, forget the misses.
- gnicholas 10y agoI'd be curious to know what else they predicted that turned out to be wrong. This could be an impressive run, or it could be that the company's press release highlights several victories and omits several (or more) failures. I have no evidence one way or the other but would be interested to see more context.

- davesque 10y agoWhat are the chances? Probably not that slim considering how many people are trying to make predictions using methods like this.
- zitterbewegung 10y agoWhat UNU does is more like "An live online poll of a group of people picked the post-season in July".

- mehwoot 10y ago1) The AI was just sythesizing answers given by human readers. It didn't do any of its own analysis of the data set. 2) The experiment was published in August, when the regular season was already two thirds completed. The cubs were well ahead of everybody at that point and were favourites to win (although in baseball that doesn't necessarily mean you are going to win in the postseason). Here are the standings at that Date: http://www.baseball-reference.com/games/standings.cgi?year=2016&month=8&day=4&submit=Submit+Date http://www.baseball-reference.com/games/standings.cgi?year=2... You can see that the 10 playoff teams were ranked 1-5 in each league at that point. So predicting the playoff teams was just "Which 10 teams are leading right now", which they asked humans about. The AI didn't predict the full post-season, just which two teams would be in the World Series, which happened to be the team everybody thought it would be from one league and the second placed team from the other.
