Bigger issue with offline RL in the real world (I.e. not Atari video games) has been the assumption of reward labeling. Who’s giving you reward labels at scale? In my opinion that’s why we haven’t seen any large scale real world success sto

I am talking about the accumulated error part near the end of the article, so your (uncharitable) assumption is not correct.

That is not the only problem however, because if it were self driving would be solved by 2018. The problem is central to using ML tricks for anything: when you use maximum likelihood estimates for training anything, you get no guarantees fo

The problem with ACT is very similar to the problem with MPC: if your forward model of the world is not great, it will come back to bite you. So much so that afaik ACT policies can have difficulty transferring between two instances of the s

As someone who is doing robotics and behavior cloning for a while, it’s incredibly funny to see the self-taught genius rediscover what’s been known in the field for 30 years and can be found by walking in to the first two lectures of any de

Here’s a question for you: why do we punish people who have already committed a crime? As a deterrence. This may as well be making an example of a whistleblower to signal potential future whistleblowers to stay silent.

This reminds me of a quip I heard on twitter and found quite funny. “Elon is the stupid people’s fantasy of what being smart is like, just like Trump can be a poor person’s fantasy of what being rich is like.” Don’t agree entirely in the po

A great way to be transparent would be to admit that some enormous egos prevented work that should be open from being open, and counterfactually opening them up. Sure, it may piss off microsoft, but statistically things that piss off micros

Once again, it’s a literary device; you’re doing the same thing when you call it “doomsaying”. The goal of it is to evoke a certain emotion out of the reader, which is fine in a discussion. Otherwise any conversation would be dry as a docto

So many of us know about Goodhart’s law but willfully ignorant about how that applies to modern economies. We made money to be the metric we judge things by, and now we get to enjoy or suffer the results of overoptimization on that metric.

Hyperbole is often (successfully) used as a literary device to express sentiments. Is there a sentiment expressed in the parent comment you don’t agree with? Then let’s talk about that instead of the form of the argument.

Since log(xy) = log(x) + log(y), you can simply calculate sum(log2(i) for i in range(1, 53)) :) might be a nicer formulation for when you don’t have arbitrary precision support.

Firstly, do these models learn a good physics grounding for nonsense actions? Like keep pressing down even when you are in the ground? Or will they phase you through the ground? Secondly, why are all videos like half a second long? I though
