Happy to share that I'll be talking about neuron position learning on the second day!

I have cleaned up the notebooks for my course on Optimal Transport for Machine Learners and added links to the slides and lecture notes. github.com/gpeyre/ot4ml

If it were an episode of Friends, it would be: The one where Causal Abstractions (finally) meet Causal Representation Learning! Speakers and CFP are out! See you in Rio🌴 #UAI #causality #workshop

Efficient Event-based Delay Learning in Spiking Neural Networks
Spiking Neural Networks (SNNs) are attracting increased attention as a more energy-efficient alternative to traditional Artificial Neural Networks. Spiking neurons are stateful and intrinsically recur...

That might be the most useful @neuripsconf.bsky.social post I've seen btw

Interested in estimating posterior predictives in Bayesian inference? Really want to know if your approximate inference "is working"? Come to our poster at the NeurIPS BDU workshop on Saturday - see TL;DR below.

See you at #NeurIPS2024! We’ll present two papers: 1) “Interventionally Consistent Surrogates for Complex Simulation Models”. Here, we propose a method for learning causal abstractions (“interventionally consistent surrogates”) of complex simulation models! openreview.net/pdf?id=UtTjg... (1/3)
