| # Graph Embeddings for the Collaborative Axis of KGD-BMTP | |
| The collaborative axis uses embeddings learned from a user-item graph with the following configuration: | |
| - **Embedding model**: LightGCN [1] | |
| - **Embedding dimension**: 256 | |
| - **Nodes**: Drawn from the full corpus. | |
| - **Edges**: Built from interactions in the training split only, preventing train-test leakage. | |
