8.4.2 Building a Minimal Pg2vec Model

You can build a Pg2vec model using the minimal configuration and default hyper-parameters as described in the following code:

• JShell
• Java
• Python

opg4j> var model = analyst.pg2vecModelBuilder().
                setGraphLetIdPropertyName("graph_id").
                setVertexPropertyNames(Arrays.asList("category")).
                setWindowSize(4).
                setWalksPerVertex(5).
                setWalkLength(8).
                build()

Pg2vecModel model = analyst.pg2vecModelBuilder()
    .setGraphLetIdPropertyName("graph_id")
    .setVertexPropertyNames(Arrays.asList("category"))
    .setWindowSize(4)
    .setWalksPerVertex(5)
    .setWalkLength(8)
    .build();
    

model = analyst.pg2vec_builder(
    graphlet_id_property_name="graph_id",
    vertex_property_names=["category"],
    window_size=4,
    walks_per_vertex=5,
    walk_length=8)

You can specify the property name to determine each graphlet using the Pg2vecModelBuilder#setGraphLetIdPropertyName operation and also employ the vertex properties in Pg2vec which are specified using the Pg2vecModelBuilder#setVertexPropertyNames operation.

You can also use the weakly connected component (WCC) functionality in PGX to determine the graphlets in a given graph.
