arXiv:2606.05797v1 Announce Type: new Abstract: Longitudinal treatment decisions require predicting potential outcomes under future treatment sequences in the presence of time-varying confounding, heterogeneous patient dynamics, and limited domain-specific data. Existing longitudinal causal estimators typically train a new model for each cohort or simulator. We introduce Causal Longitudinal Prior-Fitted Networks (CausalLongPFN), a prior-fitted in-context predictor for longitudinal causal prediction. The model is pretrained entirely on synthetic episodes sampled from a broad prior over temporal
The increasing sophistication of generative AI and deep learning methods is enabling more powerful causal inference techniques, especially relevant for dynamic, time-series data.
Accurate prediction of counterfactual outcomes is critical for robust decision-making in complex systems like healthcare and economic policy, where interventions have long-term, unfolding effects.
This advancement suggests a move towards more generalizable and less cohort-specific causal models, streamlining the development and deployment of predictive tools in dynamic environments.
