https://wz.ax/phase-spike-encoding-in-neurons
Not to sound arrogant but… reminds me of that famous paper where medical researcher rediscovers integration.

I mean, isn’t encoding data via phase difference about the only way you can transmit both continuous variables and events that is resistant both to “dc offset” and fading?

I always assumed biological neurons *have* to work this way…

Quanta Magazine Neurons Unexpectedly Encode Information in the Timing of Their Firing A temporal pattern of activity observed in human brains for the first time may explain how we can learn so quickly.

Deepmind Game theory as an engine for large-scale data analysis: EigenGame maps out a new approach to solve fundamental ML problems Our research explored a new approach to an old problem: we reformulated principal component analysis (PCA), a type of eigenvalue problem, as a competitive multi-agent game we call EigenGame.

Oh wow, a network that enhances photorealism of rendered images — we might finally see indie games that need realistic visuals, not just a heavily-stylized ones!
Also grass, hair, fur and other stuff still notoriously difficult to render conventionally
