New research explores identifiability in neural networks for interpretability

A new research paper titled "Complete or Sparse: A Tale of Two Identifiabilities" explores the conditions under which neural networks learn interpretable representations. The study focuses on identifiability, which is the ability to recover true latent variables from data using supervised learning. The paper introduces two data generation processes, one generative and one discriminative, and proves that optimal encoders are linear in latents when the representation has sufficient dimensions, but become nonlinear when dimensions are insufficient. The research also demonstrates that additional constraints can lead to the recovery of individual latent variables, offering insights into selective neuron responses and sparse dictionary learning.
