8.3.6 Inferring Embeddings for a Unsupervised GraphWise Model

You can use a trained model to infer embeddings for unseen nodes and store them in the database as described in the following step:

1. Infer embeddings for a Unsupervised GraphWise Model as shown in following code:
   Inferring Embeddings Using JShell

   opg4j> var vertexVectors = model.inferEmbeddings(fullGraph, fullGraph.getVertices()).flattenAll();
   opg4j> vertexVectors.write().
       db().
       name("vertex vectors").
       tablename("vertexVectors").  // indicate the name of the table in which the data should be stored
       overwrite(true).             // indicate that if there is a table with the same name, it will be overwritten (truncated)
       store();

   Inferring Embeddings Using Java

   PgxFrame vertexVectors = model.inferEmbeddings(fullGraph,fullGraph.getVertices()).flattenAll();
   vertexVectors.write()
       .db()
       .name("vertex vectors")
       .tablename("vertexVectors") // indicate the name of the table in which the data should be stored
       .overwrite(true)            // indicate that if there is a table with the same name, it will be overwritten (truncated)
       .store();

   Inferring Embeddings Using Python

   vertexVectors = model.infer_embeddings(fullGraph,fullGraph.getVertices()).flattenAll()
   vertexVectors.write().db(name="vertex vectors", "tablename", overwrite=True)

   The schema for the vertexVectors will be as follows without flattening (flattenAll splits the vector column into separate double-valued columns):

   
   +---------------------------------------------------------------+
   | vertexId                                | embedding           |
   +---------------------------------------------------------------+

   Note:

   All the preceding examples assume that you are inferring the embeddings for a model in the current logged in database. If you must infer embeddings for the model in a different database then refer to the examples in Inferring Embeddings for a Model in Another Database.
