Iterative Refinement Coordinator

Software componentOrchestrationOrchestration & Toolsarc:IterativeRefinementCoordinator

A coordinator that runs repeated bidirectional exchange cycles between neural and symbolic components, feeding symbolic hypotheses back as attention cues, until confidence, diminishing-returns, or iteration-limit criteria are met.

Responsibility. Coordinates neural-symbolic feedback cycles until convergence or a stop criterion.

Also known as: Cooperative architecture, Iterative pattern controller

Design guidance

MUST define explicit termination criteria because convergence is not guaranteed.
SHOULD define information exchange protocols stating what each component communicates and how receivers interpret it.

Classification

Patterns: Cooperative (iterative) neural-symbolic integrationHypothesis-driven attention
Quality attributes: Functional suitability: correctness and validity (ISO/IEC 25010 | NIST AI RMF: valid)
Risks mitigated: Oscillation between competing hypothesesOne-way information flow of pipelines
