What about a clock that has 3 "hands" that are just complete 360 motionless disks? Then it's right from every possible perspective

A clock that's off by even a single minute is never right. :)

A clock not running at all is exactly right twice a day. A clock one minute off is never right.

Wrong with probability one though, but I suppose almost all clocks are

You just need a correctly-tuned strobe to read it (or a pair of shutter glasses, I guess).

This is why we need loss functions.
-
How do you define loss functions here?
-
Thanks a lot. I have read it but I only understood parts. Mind explaining, how would a loss function be built here? How would it help?
-
In Eliezer's example, the clock is right many times, but wrong by six hours on average. A loss function is that chosen measure of deviation.
-
I understand the very high level concept but what does the loss function look like actually here?
-
It's the average distance from the truth. Inputs are the estimated and true time of day, and outputs are average distance between them.

Wrong metric. In either L1 or L2 (and especially in Linf!) metrics such a clock sucks. The joke is funny though.
