🧠 New paper by Clark et al. (2025) shows that the #dimensionality of #PopulationActivity in #RNN can be explained by just two #connectivity parameters: effective #CouplingStrength and effective #rank. Uses networks with rapidly decaying singular value spectra and structured overlaps between left and right singular vectors. Could be useful for interpreting large scale population recordings and connectome data I guess:

Hebden Bridge has lost a phone mast. No prior warning just everyone on some networks like O2 just losing signal overnight. But hey the Government wants us all to have digital ID so that’s alright even if we can no longer even access the internet! #rural #connectivity #DigtialID
