What's the practical difference between "text" and one-hots of said "text"? One-hots are the standard for inputting text into models. It is only recently that we expect models to learn their preferred encoding for raw text (cf. transformers). By taking a small shortcut, the authors of this paper get to show off their agent work without loss of generality: one could still give one-hot instructions to an agent that is learning to act in the real life.
The last time CM was mentioned on here I looked up his old videos about Fauci. In a video from Sept 2020 he made a very confident claim that NYC had already achieved 70% infections and thereby herd immunity. That turned out to be untrue:
So my prior for him is now skewed toward "pundit" rather than "honest inquirer."
Immune response is generally associated with age and lifestyle. What can you tell us about those factors?
it means contact tracing becomes easier and lockdowns more effective.
I read that oppositely. If the serial interval is shorter, contact tracers need to work faster to inform those exposed, lest those exposed become infected and transmitting. Likewise, lockdowns would only become more effective if the time each person is contagious is reduced. IIRC the delta variant, according to Indian accounts, is significantly contagious for three weeks from the date of infection as opposed to the usual two.
Re: quarantines for fully vaccinated travellers
The problem a national government has in setting quarantine standards for vaccinated people is that there are so many inconsistencies to vaccines, and the topic is wrapped in geopolitics.
The cost to administration of such an exemption program is high, the social, political, and medical perils are many, and there is the chance of quarantine escape in >5% of cases. Vaccine exemption from national quarantine is unlikely.
