New field theory framework aids transformer interpretability

Researchers have developed a new theoretical framework for understanding interventions in transformer models, drawing parallels to field theory. This approach treats the transformer's residual stream as a depth-token field, enabling the formulation of patching as localized source insertion and patch effects as sensitivity predictions. The framework was tested on GPT-2 style models, identifying a local linear regime and demonstrating the ability to predict patch effects from first-order sensitivities. AI
