GraphEmbedding
GraphEmbedding is a graph network representation library and node embedding framework. It provides a toolkit for transforming complex network nodes into low-dimensional vector spaces, enabling the integration of relational graph data into machine learning workflows.
The library functions as a dimensionality reduction toolkit and network topology analysis tool. It uses matrix-factorization techniques to preserve global connectivity and employs random-walk sampling with skip-gram based vector optimization to learn numerical representations of nodes.
The framework covers several domain-specific capabilities, including node classification analysis, link prediction modeling, and network topology visualization. It also supports graph-based feature engineering by converting discrete node identifiers into continuous vectors for predictive modeling.
