25.11.2021 · I am trying to implement a GCN layer using tensorflow, but it is not learning. Can someone check what potential issue could be? I have tried normalizing the adjacency matrix and even replaced it with

18.10.2019 · Our code is based on the orginal GCN framework, and takes inspirations from GraphSAGE and FastGCN. The core of this code is that we separate the sampling (i.e. sampler) and propagation (i.e. propagator) processes, both of which are implemented by tensorflow. Please note that it is possible that the results by this code would be slightly ...

T-GCN: A Temporal Graph Convolutional Network for Traffic Prediction. Accurate and real-time traffic forecasting plays an important role in the Intelligent Traffic System and is of great significance for urban traffic planning, traffic management, and traffic control.

In this experiment, we are going to build and train a GCN model using Spektral API that is built on Tensorflow 2.

Creating the GCN layers and data input using StellarGraph. Training and evaluating the model using TensorFlow Keras, Pandas and scikit-learn.

built a TensorFlow Keras model and data generator with the StellarGraph library. trained and evaluated it using TensorFlow and other libraries. For problems with only small amounts of labelled data, model performance can be improved by semi-supervised training. See the GCN + Deep Graph Infomax fine-tuning demo for more details on how to do this.

23.01.2020 · In this work, we present new ways to successfully train very deep GCNs. We borrow concepts from CNNs, mainly residual/dense connections and dilated convolutions, and adapt them to GCN architectures. Through extensive experiments, we show the positive effect of these deep GCN frameworks. [Tensorflow Code] [Pytorch Code]
