Learning to Defer in Non-Stationary Time Series via Switching State-Space Models

arXiv:2601.22538v2 Announce Type: replace Abstract: Learning-to-defer (L2D) routes each decision to a system's own predictor or to an external expert. Streaming time-series settings break the offline-L2D assumptions: the data are non-stationary, expert availability shifts over time, and the internal predictor is trained online. We propose L2D-SLDS, a one-stage online L2D framework based on a factorized switching linear-Gaussian state-space model over all potential residuals: a discrete regime, a shared global factor, and per-expert idiosyncratic states. The always-observed internal residual co

Why this matters
Why now

This research addresses the growing need for robust AI decision-making in real-time, non-stationary environments, which is critical for increasingly dynamic AI agents.

Why it’s important

Advanced 'learning to defer' capabilities will enhance the reliability and adaptability of autonomous AI systems, reducing errors and improving performance in complex operational settings.

What changes

AI systems can now more effectively manage uncertainty and delegate tasks between internal models and human experts in fluctuating, real-time data streams.

Winners
  • · AI Agent developers
  • · Automation industries
  • · Real-time decision systems
Losers
  • · Outdated online learning algorithms
  • · Static AI deployment models
Second-order effects
Direct

More resilient and trustworthy AI deployments in critical applications like finance, logistics, and resource management.

Second

Accelerated adoption of AI agents in environments where human-AI collaboration on decision-making is paramount.

Third

Reduced burden on human experts by enabling AI to intelligently triage and manage tasks, potentially leading to new human-AI organizational structures.
