Robustness of Algorithms for Causal Structure Learning to Hyperparameter Choice

We find that, while the choice of algorithm remains crucial to obtaining state-of-the-art performance, hyperparameter selection in ensemble settings strongly influences the choice of algorithm, in that a poor choice of hyperparameters can lead to analysts using algorithms which do not give state-of-the-art performance for their data.

We also find hyperparameter tuning and model evaluation are much more important than causal estimators and ML methods.
