Accurate GraphSage Embedding Generation

Hi,
I am training the GraphSage model for embeddings with 64 dim like below

CALL gds.beta.graphSage.train(
  'products',
  {
    modelName: 'productsGraphSage',
    nodeLabels: ['Group', 'Group1'],
    relationshipTypes: ['HAS_GROUP1'],
    featureProperties: ['group1_count', 'length'],
    embeddingDimension: 64,
    projectedFeatureDimension: 2,
    epochs: 10
  }
)

The model converged but generated embeddings are quite close to each other. Generated embeddings are always in this range

[0.0125671e-16, 0.0125672e-16, .......]

I am doing binary node classification by taking embeddings as input. The classification result gives me accuracy near to 50% only.

However, If I generate embeddings with FastRP algo, generated embeddings are quite good. It varies from +1 to -1 and my node classification algorithm also gives me 95% accuracy.
Seems like something is missing in GraphSage algo. Can someone help me to identify the actual cause of this issue?

Currently, GraphSage is not that much fast and accurate. Maybe in the coming years Neo4j will work on it.
