Description
The tkipf/relational-gcn repository offers a Keras-based implementation of Relational Graph Convolutional Networks (R-GCNs). This tool is specifically engineered for semi-supervised node classification tasks on directed relational graphs. It serves as a valuable resource for researchers and practitioners aiming to replicate or build upon the findings presented in the paper "Modeling Relational Data with Graph Convolutional Networks" (2017).

The implementation focuses on the entity classification aspect of relational data modeling. Users can leverage this code to experiment with R-GCNs on various datasets, including AIFB, MUTAG, BGS, and AM, as detailed in the usage instructions. The project emphasizes the importance of specific dependency versions, recommending Keras 1.2.1 and Theano 0.9.0, as newer Keras versions may disrupt the Theano sparse matrix API. While TensorFlow can be used as a backend, users should be aware of potential limitations regarding sparse matrix size.
To ensure accurate reproduction of experimental results, the repository provides clear instructions for dataset preparation and model training. It also includes guidance on configuring the Keras backend to Theano and enforcing CPU execution, which is recommended due to potential GPU memory limitations for certain experiments. The project is licensed under the MIT license, promoting open access and modification. The associated paper, cited as [1], offers a deeper theoretical understanding of the R-GCN model and its applications in modeling relational data.
This implementation is particularly useful for those working with graph-structured data where relationships between entities are crucial. It enables the application of advanced deep learning techniques to understand and classify nodes within complex relational networks. The code is publicly available on GitHub, fostering collaboration and further development within the graph neural network community.

Getting Started with Relational Graph Convolutional Networks
Install dependencies: Run 'python setup.py install' after ensuring compatible versions of Keras and Theano.
Configure Keras backend: Create '~/.keras/keras.json' to set 'backend' to 'theano'.
Prepare dataset: Execute 'python prepare_dataset.py -d <dataset_name>' for specific datasets (e.g., aifb, mutag).
Enforce CPU execution: Use 'CUDA_VISIBLE_DEVICES=' before the training command.
Train the model: Run 'python train.py -d <dataset_name> --bases <num> --hidden <num> --l2norm <value> --testing'.
Reproduce paper results: Follow dataset-specific instructions for AIFB, MUTAG, BGS, and AM.
Adapt for new tasks: Modify scripts for custom datasets or variations of relational graph tasks.
