New SBD framework challenges causality in language models

A new research paper proposes the System Behavior (SBD) framework, which incorporates system behavior as a fundamental component alongside data distribution. The framework theoretically identifies a "Causality Tax" phenomenon, suggesting that strict adherence to causality can be suboptimal due to overlooking system behavior. To mitigate this tax, the paper introduces Green Shell (GSH), a non-causal variational family that partitions system behavior components. Evaluations using Neural Tangent Kernel (NTK) indicate that GSH achieves tighter error bounds and superior generalization compared to causal approaches. AI

IMPACT Proposes a new theoretical abstraction for language models, potentially influencing future model design and optimization strategies.
