Pseudocode Yes Algorithm 1 SEM-UCB: Structural Equation Model-Upper Confidence Bound
Open Source Code No The paper does not provide any explicit statement or link regarding the open-sourcing of the code for the described methodology.
Open Datasets Yes We focus on the recorded daily new cases from 10 August to 15 October, 2020, for N = 21 regions within Italy.1 The Covid-19 dataset only provides us with the overall daily new cases of each region. ... 1https://github.com/pcm-dpc/COVID-19
Dataset Splits Yes We split the data into train and validation sets in 10:1 ratio. More specifically, we split the data into 6 subsets of 11 consecutive days. In each subset, one day is chosen uniformly at random to be included in the validation set while the remaining 10 days are added to the train set.
Hardware Specification No The paper does not provide any specific hardware details (e.g., CPU/GPU models, memory amounts) used for running the experiments.
Software Dependencies No The paper mentions 'OSQP solver [Stellato et al., 2020]' as an example for computational complexity but does not provide specific version numbers for this or any other software dependencies used in the experiments.
Experiment Setup Yes Finally, in our experiments, we choose s = 6, meaning that the algorithms can choose 6 base arms at each time of play. ... The regularization parameter λ is tuned by grid search over [0.0001, 1000].
