I think we have the mathematical tools to argue for the efficacy and outcomes of interventions in these situations, and the people conducting the experiments are well-equipped to use them.
The demand should be for rigorous analysis, not “you must use this approach”. We are not in primary school.

Have we some “explanation” or “reasoning” as to how instabilities are caused?
Could you explain how info is propagated across layers in your approach vs densenet in some more details over the conversation?
How do your approaches scale when we need to do RL on say LLMs?
2/2 (for now) Thanks again!

Beautiful work, thank you for the overview!
I haven’t done RL work in half a decade — I thought delayed updates with exp moving average of target networks helped deal with these instabilities. I assume it’s not enough given your paper.

If this is indeed it, then we have good reasons to be optimistic, no?

Maybe I am just seeing things, but it looks like we are past the upper inflection point of the sigmoid.

Don’t worry, scientists thought of that as well. There is a whole science of communicating with future people that don’t speak our language.

The very active isotopes of fast-breeder-reactor waste decay over 300 years and need containment.
The very inactive isotopes take thousands of years and are indistinguishable from background radiation. They pose a problem only when ingested or inhaled.

So personally, if the choice was living close to a nuclear reactor or storage facility vs living next to a battery factory or a solar factory, I’d take my chances with the former.

Your risk of developing cancer is hundreds of times higher tanning in the sun on a high UV day than living close to a containment facility.

For fast breeder reactors, the half-life of the more active isotopes is 300 years, then it gaps to thousands of years for the longer dated ones.
The longer dated isotopes are so inactive they might as well be background radiation. In fact, for them to do damage they need to be ingested or inhaled.

So the important thing to know is that longer lived isotopes are less dangerous than shorter dated isotopes. Inversely proportional actually [1].

It also implies not being dogmatic about particular solutions or fear mongering about things we don’t actually understand and shoving our head in the ground like ostriches.
It is in our best interest to think in 5 years, in 10, in 20, and in 50.

That implies reducing waste, improving efficiency, reducing reliance on complex chains, funding sciences, math, physics, material science, chemistry, biochemistry, biology, computational sciences and so on.

But because the constant supply chain issues reverberated across markets, resulted in difficult to predict outcomes, and threatened stability.
It follows then that the right thing to do to protect our society is reduce the fragility of the system.

As much as I hate to say this, the cynic in me believes that we did not make the decision to go off oil not because of climate change leading animals to extinction and threatening ordinary population.

Just assertions that can be dismissed with the same effort you spent writing them, and a “gotcha” that lost you any and all credibility.

Of course your argument is also a whole lot of bullshit because you are not arguing in good faith here.

After breeder reactor processing, the waste is primarily fission products that decay to safe levels in 300-500 years, leaving only seven very long-lived isotopes (200,000+ year half-lives) at very low activity levels.
