This was fun! We talked about one of my favorite papers/collaborations -- the WEGD (within ensemble graph distance), and we can use graph distances to study things like *teleology* in networks.

The breakthroughs just keep coming in machine learning.
And at a faster and faster pace.

IMHO, diffusion models are as big a breakthrough as transformer models. It's a rare development when an architecture requires fewer compute resources than previous proposals. lilianweng.github.io/posts/2021-07-

Comparison of virtual communication vs in-person groups. Interesting how the study tries to come up with a mechanism explanation for why it would be different.
What makes art great? Connections.
This paper examines 500,000 artists and finds long-term success is determined by the prestige of their first exhibits & how connected those galleries are. It is hard to break into fame if you don’t start with high status science.org/doi/full/10.11

Remote teams need to be set up to be bursty, switching between solo work & intense group bursts where everyone is exchanging info together at the same time. The bursts allow idea exchange & solo time gets work done. A 1 SD increase in burstiness increases team performance by 29%.

Frauen in der Gruppe steigern die kollektive Intelligenz, so lautet eines der Ergebnisse einer Metaanalyse über Teamleistungen. Am wichtigsten sind nicht individuelle Fähigkeiten, sondern die Zusammenarbeit in der Gruppe.
