Schema Integration

Schema integration represents the process by which new information is incorporated into existing knowledge structures. Within the active inference framework, it implements hierarchical model updating through precision-weighted prediction errors that optimize the balance between existing schemas and new evidence.

Mathematical Foundations

Schema Dynamics

1. Integration Process

   S'(t) = S(t) + α(E(t) - P(t))W(t)
   

   where:

   • S'(t) is updated schema
   • S(t) is current schema
   • E(t) is new evidence
   • P(t) is prediction
   • W(t) is precision weight
   • α is learning rate

2. Prediction Error

   ε(t) = E(t) - P(S(t))
   

   where:

   • ε(t) is prediction error
   • E(t) is evidence
   • P(S(t)) is schema prediction

Knowledge Organization

1. Hierarchical Structure

   P(h|e) = P(e|h)P(h)/P(e)
   

   where:

   • h represents hierarchical level
   • e represents evidence
   • P(h) is prior probability
   • P(e|h) is likelihood

2. Integration Cost

   C(S,E) = D_KL(P(S')||P(S)) + λH(S')
   

   where:

   • D_KL is KL divergence
   • H is entropy
   • λ is complexity cost
   • S,S' are old/new schemas
