I always heard the version that went the other way around. After it was shown that single layer perceptrons were unable to deal with data sets that weren't linearly separable, there was an effort to figure out how the single layer tank classifier was working.
- gwern 9y agoThat's an interesting variant - none of the versions I've seen so far link it to Minsky's perceptron book. Any chance you recall where you saw that one?
- gok 9y agoThis was from a prof giving an undergrad ML lecture at Cornell about 10-12 years ago. Wikipedia's coverage of _Perceptrons_ suggests my lecturer also had only heard the mistaken version of Minky's XOR example, so this could have been entirely wrong :)
- gwern 9y agoOh. How boring. Wonder if I should include that as an example... It's a valid example of how urban legends evolve, after all.
