1.1.4. Manifold hypothesis - Wikipedia
The manifold hypothesis posits that many high-dimensional data sets that occur in the real world actually lie along low-dimensional latent manifolds inside that high-dimensional space.
If your space is non linear, maybe it’s linear in some high-dimensional abstract vector space nonsense

1.4. Renormalization group & Neural networks
- Resumen de Marco Tavora Alto nivel, se mete con algo de matemáticas pero no demasiado
- Renormalization Group connected to Neural Networks La mejor review del tema que he encontrado hasta el momento. Modelizar las NN como redes de spines (Ising, Boltzmann Machines…), las matemáticas son las mismas y hay muchas analogías.

1.8. Generative Adversarial Networks (GANs)
- The intuition behind adversarial attacks on NN -> Las imágenes adversarias podrían estar creadas por la función de activación de las neuronas (x*(x>0) en vez de más robustas como tanh(x) o sigm(x)) que se sobreexcita al no estar acotada por arriba.
