Research Type Experimental Numerical experiments with decentralized control systems showcase the effectiveness and stability of the proposed ST-GNNs. Our theoretical findings are also supported by thorough experimental analysis based on decentralized control applications.
Researcher Affiliation Academia Department of Electrical and Systems Engineering University of Pennsylvania EMAIL
Pseudocode No No pseudocode or algorithm blocks were found in the paper.
Open Source Code No We used the GNN library at https://github.com/alelab-upenn/graph-neural-networks
Open Datasets No The dataset is generated according to the mobility model in (95) and (96). The dataset consists of 500 time-varying graph signals {Xm}500 m=1 that are calculated under optimal centralized policies {U m}500 m=1.
Dataset Splits Yes We split the data into 460 examples for training, 20 for validation and 20 for testing.
Hardware Specification No No specific hardware details (e.g., GPU/CPU models, memory amounts) used for running experiments were mentioned in the paper.
Software Dependencies No We used the GNN library at https://github.com/alelab-upenn/graph-neural-networks
Experiment Setup Yes We train a 2-layer ST-GNN on the training data and optimize the mean squared loss using ADAM algorithm with learning rate 0.01 and decaying factors β1 = 0.9 and β2 = 0.999.
