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

🔥 Got a great work on causal representation learning, abstraction, high-dimensional discovery, or other hot topics in causality?

🇧🇷 Don’t miss your chance to present in Rio at the CAR Workshop at #UAI2025!

⏰ Deadline is in 1 week – May 26!

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🌴

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...

NeurIPS 2024 officially started yesterday!

Over 60 papers on causality have been accepted this year, but...

...that's not all!

You can also attend 2 causal workshops (another tutorial took place yesterday) and a workshop on sequential experiment design.

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)

This work leverages Causal Abstraction theory to build causally consistent surrogates for complex simulation models, enabling more efficient policy evaluation and decision-making.

Interventionally Consistent Surrogates for Complex Simulation Models
Large-scale simulation models of complex socio-technical systems provide decision-makers with high-fidelity testbeds in which policy interventions can be evaluated and _what-if_ scenarios explored....
