SCDM: Scalable Causal Discovery in Nonlinear Temporal Systems with Meta-Learning
We propose SCDM, a shared-parameter meta-learning framework for scalable temporal causal discovery.
ProofPaper ↗
Key points
- Causal discovery from nonlinear multivariate time series is challenging in high-dimensional systems, where the number of candidate directed relations grows quadratically with the number of variables.
- SCDM treats each target variable as a task while learning a shared temporal predictor and a shared causal-strength matrix across tasks.
- After training, a post-training graph readout converts the learned predictor into continuous directed causal scores for threshold-independent evaluation.
- Experiments on controlled synthetic, neuroimaging-inspired, high-dimensional, and real-world temporal benchmarks demonstrate competitive causal recovery and improved scalability in large temporal systems.
