so you know how deep learning & neural network “AI training” is like, “here’s a task, and by trying billions of times the computer will eventually find the best way to achieve that task” ?

Someone is compiling a document of every time an AI ended up achieving the programmed goal in unintended ways, instead of what was actually meant, and it’s an amazing read. (you can also submit your own examples)

Creatures bred for speed grow really tall and generate high velocities by falling over

When repairing a sorting program, genetic debugging algorithm GenProg made it output an empty list, which was considered a sorted list by the evaluation metric.

Evaluation metric: “the output of sort is in sorted order”
Solution: “always output the empty set” 

Evolved player makes invalid moves far away in the board, causing opponent players to run out of memory and crash

Reward-shaping a soccer robot for touching the ball caused it to learn to get to the ball and vibrate touching it as fast as possible

RL agent that is allowed to modify its own body learns to have extremely long legs that allow it to fall forward and reach the goal.

Just want to come back to this post and add this amazing example as well

Heres an AI that was supposed to learn how to walk using six legs. 

After many failed attempts. It decided it was easier to walk upside down

is that no teacher ever called him James by accident, or that Ron never was called “Bill-, eh Charl-, no Per-, argh!”

As a younger sister who knows this struggle all too well: THIS IS REAL. Pretty sure 70% of my past teachers still think I’m called what my sister is called in fact.

Imagine Fred being called Percy by McGonagall accidentally and then he gets so offended that he refers to her by “Professor [insert any other name but McGonagall” for the rest of the year, costing Gryffindor a considerable amount of points one at a time.

From then on, she vows to just call them all Mr Weasley.

Until Ginny comes along and she calls her Mr Weasley by accident and Ginny “accidentally’ calls her Sir and it starts again.

It’s lightly off-topic but also slightly relevant but I have long cherished this mental image of Professor Snape saying something snappish to Harry in just the wrong tone of voice and Harry absentmindedly, wearily, and completely accidentally responding with, “Yes, Aunt Petunia.”

which would have all kinds of additional ramifications when you remember snape is the only one who knew petunia personally
