📰 ArXiv cs.AI
Learn when LLM self-correction helps using a control-theoretic Markov diagnostic and verify-first intervention, and apply this knowledge to improve LLM systems
Action Steps
- Frame self-correction as a cybernetic feedback loop in LLM systems using a two-state Markov model
- Calculate the expected correction rate (ECR) and expected incorrect rate (EIR) for the LLM system
- Apply the diagnostic iterate only when ECR/EIR > Acc/(1 - Acc) to determine when self-correction helps
- Implement a verify-first intervention to validate the effectiveness of self-correction
- Test and refine the LLM system using the control-theoretic Markov diagnostic and verify-first intervention

Title: When Does LLM Self-Correction Help? A Control-Theoretic Markov Diagnostic and Verify-First Intervention
Abstract:
arXiv:2604.22273v1 Announce Type: new Abstract: Iterative self-correction is widely used in agentic LLM systems, but when repeated refinement helps versus hurts remains unclear. We frame self-correction as a cybernetic feedback loop in which the same language model serves as both controller and plant, and use a two-state Markov model over {Correct, Incorrect} to operationalize a simple deployment diagnostic: iterate only when ECR/EIR > Acc/(1 - Acc). In this view, EIR functions as a stability ma
