The team proposes a “fairness-aware” path reranking algorithm for explainable recommendations to remedy this, following from the observation that knowledge graphs consider user-item paths as ...

Point-of-Interest (POI) recommendation is crucial in the recommendation system field. Graph neural networks are used for POI recommendations, but data sparsity affects GNN training.

Short algorithm, long-range consequences Date: March 2, 2013 Source: Massachusetts Institute of Technology Summary: A new technique for solving 'graph Laplacians' is drastically simpler than its ...

Graph analytics is a hot topic, but what does it mean? At the DC GraphTour, I learned the difference between graph queries, graph algorithms, and graph analytics. Next up: San Francisco GraphTour.

Refining with colors Mathematicians have developed various strategies to compare graphs. Since the 1970s, algorithms have been able to test graph isomorphism, but in exponential time.

New information about how various factors influence YouTube’s video recommendation algorithm is revealed by members of the team responsible for working on it. Having only been implemented in ...

“The new algorithm is a remarkable tour de force,” said Giuseppe Italiano, a computer scientist at Luiss University and a co-author of the 1996 paper describing what is now the second-fastest ...
