GNN Algorithm Instructions

Pytorch on Angel provides the ability to run graph convolution network algorithm. We follow Pytorch-Geometric to define the graph convolution networks while using the parameter server of Angel to store the network structure and features of nodes.

Introduction

1. How to predict

change the input data path and output path
change actionType to predict
you can get hdfs://modelPath/xx.pt to local, then use it as training; Or you can use the hdfs path, and set --files hdfs://modelPath/xx.pt, in this way the torchModelPath can be remove

2. How to train incrementally

change the input data path and output path, or you can use the same data to train incrementally
set actionType as train
you can get hdfs://modelPath/xx.pt to local, then use it as training; Or you can use the hdfs path, and set --files hdfs://modelPath/xx.pt, in this way the torchModelPath can be remove

3. How to calculate the resource

In order to know how to set the resources, you should figure out where the data saved firstly, and then calculate how much data storage space, finally set 2~3 times of data storage. The detail calculation method refer to Resource Calculation Method

Example of GraphSage

GraphSage generates embeddings by sampling and aggregating features from a node’s local neighborhood. Here we give an example of how to run GraphSage algorithm beyond Pytorch on Angel.

Generate pytorch sciprt model First, go to directory of python/graph and execute the following command:
dense/low-sparse data:
```
 python graphsage.py --input_dim 1433 --hidden_dim 128 --output_dim 7 --output_file graphsage_cora.pt
```
high-sparse data:
```
 python graphsage.py --input_dim 32 --input_embedding_dim 8 --input_field_num 20 --encode one-hot --hidden_dim 128 --output_dim 7 --output_file graphsage_sparse.pt
```
This script utilizes TorchScript to generate a model file which contains the dataflow graph of graphsage. After that, you will obtain a model file named "graphsage_cora.pt". Here we use the Cora dataset as an example, where the feature dimension for each node is 1433 with 7 different classes.
Detailed parameter introduction reference Python Model Parameters
Preparing input data There are three inputs required for graphsage, including the edge table, the node feature table and the node label table.
The detail info see Data Format

Submit model to cluster After obtaining the model file and the inputs, we can submit a task through Spark on Angel.

Example of DGI/Unsupervised GraphSage

Here we give an example of how to run DGI algorithm beyond Pytorch on Angel.

Generate pytorch sciprt model First, go to directory of python/graph and execute the following command:
for DGI pt model:

 python dgi.py --input_dim 1433 --hidden_dim 128 --output_dim 128 --output_file dgi_cora.pt
```
for Unsupervised GraphSage pt model:
```
 python unsupervised_graphsage.py --input_dim 1433 --hidden_dim 128 --output_dim 128 --output_file unsupervised_graphsage_cora.pt
```
This script utilizes TorchScript to generate a model file which contains the dataflow graph of dgi. After that, you will obtain a model file named "dgi_cora.pt". Here we use the Cora dataset as an example, where the feature dimension for each node is 1433.
Detailed parameter introduction reference Python Model Parameters
Preparing input data There are two inputs required for dgi, including the edge table and the node feature table.
The detail info see Data Format

Submit model to cluster After obtaining the model file and the inputs, we can submit a task through Spark on Angel. The only difference between DGI and Unsupervised GraphSage is pt model, the submit scriptis same；

Example of Relation GCN (RGCN)

Relation GCN is semi-supervised graph convolution network which can utilize the types of edges. The difference between RGCN and GCN is that each edge can has different types.

Here we give an example of using RGCN over pytorch on angel.

Generate pytorch sciprt model First, go to directory of python/graph and execute the following command:
```
 python rgcn.py --input_dim 32 --hidden_dim 16 --n_class 2 --output_file rgcn_mutag.pt --n_relations 46 --n_bases 30
```
This script utilizes TorchScript to generate a model file which contains the dataflow graph of rgcn. After that, you will obtain a model file named "rgcn_mutag.pt". Where n_class is the number of classes, n_relations is the number of types for edges and n_bases is a parameter of RGCN to avoid overfitting. Detailed parameter introduction reference Python Model Parameters
Preparing input data There are three inputs required for graphsage, including the edge table with type, the node feature table and the node label table.

Example of EdgeProp

EdgeProp is an end-to-end Graph Convolution Network (GCN)-based algorithm to learn the embeddings of the nodes and edges of a large-scale time-evolving graph. It consider not only node information and also edge side information.

Here we give an example of using EdgeProp over pytorch on angel.

Generate pytorch sciprt model First, go to directory of python/graph and execute the following command:
```
 python edgeprop.py --input_dim 23 --edge_input_dim 7 --hidden_dim 128 --output_dim 7 --output_file edgeprop_eth.pt
```
This script utilizes TorchScript to generate a model file which contains the dataflow graph of edgeProp. After that, you will obtain a model file named "edgeprop_eth.pt". Where edge_input_dim is the dimension of edge feature, other parameters are same as GraphSAGE. Detailed parameter introduction reference Python Model Parameters

Example of HAN

HAN is a semi-supervised graph convolution network for heterogeneous graph. In order to capture the heterogeneous information, HAN defined two different attentions: node-level and semantic level. Here a simplified version of HAN is implemented, which accepts bipartite graph in the form of "user-item", where item nodes could have multiple types. In another words, the input graph has multiple meta-paths in the form of "user-item-user". HAN classifies user nodes, and outputs their embeddings if needed.

Here we give an example of using HAN over pytorch on angel.

Generate pytorch sciprt model First, go to directory of python/graph and execute the following command:
dense/low-sparse data:
```
 python semi_han.py --m 64 --input_dim 32 --hidden_dim 16 --output_dim 2 --item_types 5  --output_file han.pt
```
high-sparse data:
```
 python semi_han.py --m 64 --input_dim 32 --input_embedding_dim 8 --input_field_num 20 --encode one-hot --hidden_dim 16 --output_dim 2 --item_types 5 --output_file han_sparse.pt
```
This script utilizes TorchScript to generate a model file which contains the dataflow graph of han. After that, you will obtain a model file named "han.pt". Detailed parameter introduction reference Python Model Parameters
Preparing input data There are three inputs required for han, including the edge table with type, the node feature table and the node label table.
HAN requires an edge file which contains three columns including the source node column, the destination column and the node type column. The third column indicates the destination nodes' types, each type indicates a meta-path of "A-B-A".

Example of Semi Bipartite GraphSage

Semi Bipartite GraphSage is a semi-supervised graph convolution network for Bipartite graph.

Here we give an example of using Semi Bipartite GraphSage over pytorch on angel.

Generate pytorch sciprt model First, go to directory of python/graph and execute the following command:
dense/low-sparse data:

 python semi_bipartite_graphsage.py --input_user_dim 2 --input_item_dim 19 --hidden_dim 128 --output_dim 2 --output_file semi_bipartite_graphsage.pt --task_type classification

high-sparse data:

 python semi_bipartite_graphsage.py --input_user_dim 10 --input_item_dim 10 --hidden_dim 128 --output_dim 2 --output_file semi_bipartite_graphsage_sparse.pt --task_type classification --input_user_field_num 3 --input_item_field_num 3 --input_user_embedding_dim 8 --input_item_embedding_dim 16

This script utilizes TorchScript to generate a model file which contains the dataflow graph of Semi Bipartite GraphSage. After that, you will obtain a model file named "semi_bipartite_graphsage.pt". Detailed parameter introduction reference Python Model Parameters

Preparing input data There are three inputs required for han, including the edge table, the user node feature table, the item node feature table and the label table for user node.

Example of INDUCTIVE MATRIX COMPLETION BASED ON GRAPH NEURAL NETWORKS(IGMC)

IGMC IGMC trains a graph neural network (GNN) based purely on 1-hop subgraphs around (user, item) pairs generated from the rating matrix and maps these subgraphs to their corresponding ratings

Here we give an example of using IGMC over pytorch on angel.

Generate pytorch sciprt model First, go to directory of python/graph and execute the following command:
classification:
```
 supervised_igmc.py --input_user_dim 23 --input_item_dim 18 --hidden_dim 32 --edge_types 5 --output_dim 5 --output_file igmc_ml_class.pt
```

 python supervised_igmc.py --input_user_dim 23 --input_item_dim 18 --hidden_dim 32 --edge_types 5 --output_dim 5 --method regression --output_file igmc_ml_reg.pt
```
This script utilizes TorchScript to generate a model file which contains the dataflow graph of Unsupervised Bipartite GraphSage. After that, you will obtain a model file named "igmc_ml_class.pt or igmc_ml_reg.pt". Detailed parameter introduction reference Python Model Parameters
Preparing input data There are three inputs required for IGMC, including the edge table(with rating), the node feature table.
