Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T.

Research Type Experimental 5 Empirical Evaluation We evaluate our proposed meta dynamic DAG learning algorithm against some of the existing DAG learning algorithms, designed for dynamic time series datasets and/or with multi-domain capabilities. We test the algorithms on synthetic datasets as well as a simulated reinforcement learning (RL) environment, Sprites World, with intervention datasets.

Dataset Splits Yes For the online setting where we use a sliding window size of 3 previous time domains to meta-train and the current domain as the meta-test dataset.
Hardware Specification Yes The experiments are run on a machine with a 3.2 GHz CPU and 64 GB of memory.
Software Dependencies No Sprites world [69] is a Python-based RL environment in which objects of various shapes interact with each other in 2-dimensional space.
Experiment Setup Yes We search for the best value of each of 5 parameters sequentially, including two L1 penalty coefficients for W a and W b, the threshold to obtain final W a and W b, and the hidden neuron size. For λa and λw, we search over a value range of {10 5, 10 4, 10 3, 10 2, 10 1}. Graph threshold search range is set to be {0.001, 0.01, 0.05, 0.1, 0.2, 0.3}, and neuron size range is searched over {8, 16, 32, 64}. We use a two-layer MLP architecture in the experiments: Xi = W1σ((Wp,i(Ws) Ws)Xi)), where W1 is the MLP layer weight and σ is the Re LU activation function.
