What problem does it solve?
This skill addresses the need to extend the reference-free quality estimation pipeline in the ek framework, allowing developers to integrate custom signals, calibrators, and decision policies for robust extraction validation.
Core Features & Use Cases
- Custom Signal Integration: Add deterministic verifiers, intrinsic confidence signals, or agreement-based ROVER voting to the estimation pipeline.
- Calibration & Decision Logic: Implement custom calibrators like Platt or Isotonic scaling and define selective policies such as Conformal or Cost-Sensitive gates.
- Use Case: When building an OCR system, use this skill to add a custom regex-based verifier signal that flags extracted dates that do not match a valid calendar format before the decision policy accepts the output.
Quick Start
Register a new custom signal component by implementing the Signal protocol and adding it to the ek registry for use in the estimate_quality pipeline.
