Reproducibility Variable Result LLM Response
Research Type Experimental Through experiments on several node classification benchmarks, we demonstrate that our proposed method outperforms existing attention-based graph models like GATs.
Researcher Affiliation Academia 1Department of Biosystems Science and Engineering, ETH Z urich, Switzerland 2SIB Swiss Institute of Bioinformatics, Switzerland.
Pseudocode No The paper describes the EM algorithm steps and mathematical formulations but does not include a formally labeled 'Pseudocode' or 'Algorithm' block.
Open Source Code Yes Our code is available at https://github.com/Borgwardt Lab/ fisher_information_embedding.
Open Datasets Yes We assess the performance of our method with six widely used benchmark datasets for node classification, including Cora, Citeseer, Pubmed (Sen et al., 2008) as semi-supervised transductive learning datasets and Reddit (Hamilton et al., 2017), ogbn-arxiv (Hu et al., 2020), ogbn-products (Hu et al., 2020) as mediumor large-scale supervised learning datasets.
Dataset Splits Yes All results are computed from 10 runs using different random seeds with the optimal hyperparameters selected on the validation set.
Hardware Specification Yes All experiments were performed on a shared GPU and CPU cluster equipped with GTX1080 and TITAN RTX.
Software Dependencies No The paper mentions 'Adam optimizer' and 'Light GBM classifier', and 'FLAML' but does not specify their version numbers.
Experiment Setup Yes Full details on the datasets, experimental setup and implementation details can be found in the Appendix. The hyperparameters for training FIE models on different datasets are summarized in Table 3 and Table 4, respectively for unsupervised and supervised modes of FIE. For supervised learning tasks, a dropout with rate equal to 0.5 is used for training supervised embeddings of FIE.
