Graph Data Science 2.3 was just released! Check out the new features like the Minimum Directed Steiner Tree, super useful for understanding the shortest or least expensive routes when travelling from multiple locations to a specific destination. Or HashGNN, where, instead of doing neural transformations like most GNNs, transformations are done by locality-sensitive min-hashing.
We are also introducing negative relationships, which provide negative relationship examples for more options to train link prediction models and get them into production quickly. Learn more about it here.

Cheers,

Yolande Poirier
