Is this a joke? $12,000 to make a paper open access that we submit & review for free?? Even in industry research I can’t justify such a cost.
It’s the price of
-1 year rent for room in NYC
-5 cars
-10 laptops
-1/3rd annual PhD student salary
-1/2 annual nyc min wage
Outrageous.
In this scenario, the cost of publication is covered by an Article Processing Charge (APC) paid at the time of publication. The APC for Nature Neuroscience in 2022 is €9,500/US $11,390/£8,290.

I’d been surprised by the stark difference in reaction to Ukraine vs Palestine or Afghanistan. Cue the dehumanization of Afghanistan & Iraq, among the oldest civilizations, saying “oh no not in civilized Europe where we don’t expect this”. Not where the US/UK are used to bombing.
"This isn't a place, with all due respect, like Iraq or Afghanistan who has seen conflict rage for decades. This is a relatively civilized, relatively European - I have to choose those words carefully - city where you wouldn't expect that or hope that it was going to happen."

and I discuss why she's always cherished learning myriad subjects, the role of philosophy in her world, the reinforcement learning landscape, successor representations in RL, and how to name constellations.

Many science fiction stories mention uploading consciousness into a machine. Do you know of stories where they explain how they do this? No matter how banal or scientifically crazy, I’d love to read about those references if you recall any.

Episodic memory Twitter:
What are some tasks for which episodic memory is *necessary* to solve?
Asking to use as tasks to test a model on. Would appreciate any pointers! 🙏🏼

When we remember something, its associates are a bit activated too. Our model, SAMPL: Spearing Activation and Memory PLasticity, models both forgetting & enhancement of those further associations in memory. 1/n

Thanks for this, been weighing on me but didn’t share: Twitter is less supportive lately & the struggle against imposed hijab in iran is not to be confused w western islamophobia or a cry for neocolonial intervention.
Iranian women:
drop a DM if I can offer support💚

has been beaten to death by the Iranian “morality police”. As I’m writing this many have been beaten and some have died in the protests that broke out after. You might ask what the hell is a morality police and why is this happening? …

I have optimization jokes, but they're stuck in local minima.

A case for explorers communicating reward location to other agents in multi-agent RL. I wish I could see footage of the interaction!

What do you want to see in computational models of replay that is missing from existing models? I'd especially love to hear from biologists & electrophysiologists –recently I gave a talk at the Buzsaki lab & I'm still inspired by their questions.

Next meta will propose a novel alternative vision for time, which will call the temporal window during which a location of earth receives sunlight (even if cloudy) “day” and the rest “night”. They’ll add a sketch too, which is a collage of textbook images from 3 decades ago. 🤦🏻♀️
