Decomposition-Based Modular Conformal Prediction for Two-Stage Modeling

arXiv:2510.04406v2 Announce Type: replace-cross Abstract: Conformal prediction offers finite-sample coverage guarantees under minimal assumptions. However, existing methods treat the entire modeling process as a black box, overlooking opportunities to exploit and understand modular structure. We introduce a conformal prediction framework for two-stage sequential models, where an upstream predictor generates intermediate representations for a downstream model. By decomposing the overall prediction residual into stage-specific components, our method enables practitioners to attribute uncertainty

Why this matters
Why now

This research addresses a critical limitation in current AI model interpretability and reliability by introducing a methodical approach to uncertainty quantification in modular systems, crucial as AI systems become more complex.

Why it’s important

A strategic reader should care because improving the reliability and interpretability of multi-stage AI models directly impacts the trustworthiness and deployment potential of advanced AI systems in critical applications.

What changes

The ability to attribute uncertainty to specific stages within sequential AI models allows for more targeted improvements, better error diagnosis, and potentially more robust system design.

Winners
  • · AI developers
  • · High-stakes AI applications (e.g., medical, autonomous driving)
  • · AI explainability platforms
  • · MLOps platforms
Losers
  • · Black-box AI models
  • · Systems with undifferentiated error reporting
Second-order effects
Direct

Individual components of complex AI systems can be evaluated and optimized for uncertainty more effectively.

Second

This could lead to a proliferation of modular, verifiable AI architectures, increasing confidence in AI deployments for sensitive tasks.

Third

Improved modular reliability facilitates the development of larger, more complex AI agents that can attribute and mitigate errors internally, accelerating the 'ai-agents' paradigm.
