Built me a little "Goldilocks" zone finder. It's based on a feedback-loop with a convolutional shader that has 13 parameters - the problem is that about 95% of random parameter combinations result in a dead system that either goes to full black or white, but there is a zone where the parameters are just right and the system stays alive, but it's not a simple "stay in this range" issue. So I trained a small model which tries to predict which parameter combinations are promising in order to explore the space of interesting systems. And now the model keeps improving itself by continuously testing its assumptions and retraining itself. And its "hit" rate is much better than me pressing the space bar.

@niko_kukushkin I guess spirals come from phase-coupled oscillators dynamics. They are common in dissipative systems (en.wikipedia.org/wiki/Belousov%…{

@lerandomart @monkantony_tez @zzznah @MIT @medialab Very interesting conversation! A small nitpick: in the part where Alex describes what came after CPPNs, the term "narrowed rendering fields" is used. I couldn't find this term anywhere in the internet except this article. Maybe you've meant neural radiance fields?

@zzznah Happy DeepDream day!

Ten years ago I woke up in the middle of the night from an uncanny dream. Unable to sleep, I decided to try an experiment that had been on my mind for days. In half an hour, the strange phenomenon that would flood the internet that summer was born. Happy DeepDream day! youtu.be/YqhdzaclxKo

Here's a new preprint on #bioelectricity from our voltage imaging and developmental biology wizard @DrPTMcMillen: osf.io/preprints/osf/… "The neural crest as a bioelectric Rosetta Stone: translating the analog and digital bioelectric code with Fluorescent Lifetime Imaging (FLIM)" Abstract: "Translating the bioelectric code remains one of the core challenges to widespread biomedical translation of bioelectric interventions, as well as a better evolutionary understanding of how developmental ionic signaling became the basis of neural intelligence. Thus, it is essential to develop model systems and protocols in which diverse bioelectrical parameters can be quantitatively studied together, in the living state, and connected to cell- and tissue-level outcomes. Here, we apply state-of-the-art quantitative Fluorescent Lifetime Imaging (FLIM) optical estimation of membrane potential (Vmem) to map the bioelectric dynamics of spreading Xenopus laevis neural crest cells over roughly 18-hour time periods. We identify a slow “analog” bioelectric component that functions on the scale of hours, and a faster “digital” component that acts on the scale of seconds. We then use information theory to show that digital NCC Vmem dynamics are largely distinct from calcium dynamics. Finally, we provide a survey of diverse bioelectric events revealing a deep complexity in collective bioelectric dynamics, likely involving tunneling nanotubes in their transmission, which suggests numerous avenues for further investigation."
