an interesting part of that chomsky quote is comparing russia's actions to a "hurricane" like it's political force majeure and not a series of choices. once again everyone (except the US of course) is mechanistically enacting the laws of history

Introducing NovGrid: a testbed for experimenting with RL agents facing novel environmental changes arxiv.org/abs/2203.12117 github.com/eilab-gt/NovGrid Novelty is a sudden change to the world dynamics at test time, after an agent’s policy has converged and learning is turned off.
On the left a grid environment with a door that takes a yellow key. Underneath a reward curve. On the right the same environment but the door needs a blue key. Underneath a shallow reward curve for non-novelty aware agents and an steep curve for novelty-aware agents.

The AI-Collaborative tool I use to make my new work should launch tomorrow, if all goes to plan server-side. Reminder that I still intend to collect several ETH of AI art this month into next, with preference given to work using this tool in the creative process. Can't wait.🌟
