I have trained the model using ModelNet40 train data(2048 points, 250 epochs) and results are good when I try to classify objects using ModelNet40 test data. Putting it together, we have the following SageConv layer. Training our custom GNN is very easy, we simply iterate the DataLoader constructed from the training set and back-propagate the loss function. This function calculates a adjacency matrix and I think my gpu memory cant handle an array with the shape of 50000 x 50000. As for the update part, the aggregated message and the current node embedding is aggregated. This function should download the data you are working on to the directory as specified in self.raw_dir. I trained the model for 1 epoch, and measure the training, validation, and testing AUC scores: With only 1 Million rows of training data (around 10% of all data) and 1 epoch of training, we can obtain an AUC score of around 0.73 for validation and test set. LiDAR Point Cloud Classification results not good with real data. When implementing the GCN layer in PyTorch, we can take advantage of the flexible operations on tensors. At training time everything is fine and I get pretty good accuracies for my Airborne LiDAR data (here I randomly sample 8192 points for each tile so everything is good). The superscript represents the index of the layer. The PyTorch Foundation supports the PyTorch open source with torch.no_grad(): PyTorch Geometric Temporal is a temporal (dynamic) extension library for PyTorch Geometric. Each neighboring node embedding is multiplied by a weight matrix, added a bias and passed through an activation function. The score is very likely to improve if more data is used to train the model with larger training steps. Message passing is the essence of GNN which describes how node embeddings are learned.
