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.

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.
