#ChatGPT, despite all the indicia of #intelligence, appears to be nothing more than an exploitation of the #LawOfLargeNumbers.

Why is the Law of Large Numbers important when estimating likelihood ratio policy gradients?

Because it allows us to compute an unbiased estimate of an expectation as a sum, see the attached image.

Some of my notes on likelihood ratio policy gradients are here: http://www.1-4-5.net/~dmm/ml/lln_policy_gradient.pdf.

As always, questions/comments/corrections/* greatly appreciated.

#LawOfLargeNumbers Rang to chase a missing prescription - receptionist asked for my date of birth and then said - that's the same as mine - I said I don't think you were born in '59 - she said -your right but I was born on same date in '95 :)
