Gradland study links physical interaction structure to phenomenal experience

VERA Brief

AI-generated. Grounded in the article and its cited sources.

A new paper proposes a model called Gradland where the structure of physical interactions, specifically gradients, characterizes phenomenal experience. The research introduces measures for Jacobian structure to account for various aspects of subjective experience.

Key facts

• A paper published on arXiv suggests that the first-order structure of physical interactions, termed gradients or Jacobians, may define the structure of phenomenal experience.
• The research introduces an idealized environment, Gradland, populated by differentiable neural networks where physical laws are known.
• Two metrics for Jacobian structure, effective rank and cohesion, are presented, drawing on Kirchhoff complexity.
• The study suggests this hypothesis explains phenomena including the duration of experience, the distinction between vivid and obscure perception, the experience of texture, and the confusion presumed in newborns.
• The framework is proposed to account for the difference between distinct and confused ideas, the nature of learning, and the function of rich, dense experience.
