What is a causal model and how is it different from a "common" statistical model?
π
Thread on a mental picture and intuition how one may think about (a subclass of) causal models and the causal discovery problem.

Why?
We need ππππππ performance metrics to guide the development of ππππππ structure learning algorithms.
Existing graph distances are non-causal,
ignore causal order, or slow π
We develop new algorithms for
the too fast π΄ββοΈ and too causal

Using Neuro-Symbolic AI can boost the prediction accuracy... but are you learning the right concepts? π€
The answer is very tricky, but it is "no" in general π±
