Mechanistic Interpretability: Unpacking Neural Network Algorithms

This paper provides a comprehensive overview of mechanistic interpretability, a field focused on reverse-engineering the internal algorithms of neural networks. It delves into Transformer circuit analysis, examining how components like attention mechanisms and induction heads contribute to complex tasks and in-context learning. The research also addresses the challenges of superposition and polysemanticity by showcasing tools like Sparse Autoencoders (SAEs) for decomposing network activations into interpretable features. Furthermore, the paper discusses methods for controlling model behavior through steering vectors and causal interventions, and connects these insights to neurosymbolic AI frameworks for translating neural representations into logical rules.
