SL-BiLEM: Structured Learnable Behavior-in-the-Loop Epidemic Modeling for Forecasting and Policy Evaluation

arXiv:2605.26704v1 Announce Type: new Abstract: Epidemic forecasting faces a fundamental challenge: human behavior dynamically responds to disease spread, creating feedback loops that induce distribution shifts at policy intervention points. This renders data-driven models unreliable under distribution shift. We propose \textbf{SL-BiLEM} (Structured Learnable Behavior-in-the-Loop Epidemic Model), leveraging physical constraints as regularization for robust extrapolation. The framework decomposes effective transmission as $\beta_{\text{eff}}(t,g) = \beta_0(g) \times m_{\text{policy}}(t) \times

Why this matters
Why now

This research addresses the ongoing challenge of accurate epidemic forecasting in the face of dynamic human behavior, a persistent issue highlighted by recent global health crises.

Why it’s important

Accurate epidemic modeling that accounts for human behavior and policy intervention is crucial for public health, economic stability, and effective governance.

What changes

Epidemic models could become more robust and reliable, providing better foresight for policy decisions and reducing the economic and social disruption of future outbreaks.

Second-order effects
Direct

Improved epidemic forecasting models that account for human behavioral feedback loops.

Second

More effective and timely public health interventions due to better predictive capabilities, potentially reducing disease spread and economic disruption.

Third

Enhanced trust in government responses to health crises and potential for early warning systems that dynamically adapt to population behavior.
