Graph Data Science 2.3.2

GDS 2.3.2 is compatible with Neo4j 5 & 4.4 versions (≥ 4.4.9).

For GDS compatibility with previous releases, please use GDS Compatibility Table.

New features

Neo4j Database Compatibility

• This release is compatible with all Neo4j 5.x database version <= 5.6.0. Please see our compatibility matrix above.

Bug fixes

• Graphs imported via Arrow no longer cause invalid node mappings that produced ArrayIndexOutOfBoundsExceptions
• Correct memory estimation of Leiden for very small graphs
• KNN no longer result in an AIOOB exception if the array node properties did not exist for some nodes
• CELF no longer returns negative gains for some nodes
• GraphSage will no longer return NaN values because of incorrect neighbor sampling

Improvements

• More accurate memory estimation on Node Similarity and filtered Node Similarity algorithms for high topN or topK values.
• The gds.alpha.modularity procedures for computing modularity no longer require each community to be smaller than the size of the graph.
• Improve the progress logging of gds.graph.project.cypher to be more accurate. Especially, this avoids underestimating when the relationship query is more complex.
