Searching to Sparsify Tensor Decomposition for N-ary Relational Data [article]

Shimin Di, Quanming Yao, Lei Chen
2021 arXiv   pre-print
Specifically, we propose a new tensor decomposition framework, which allows embedding sharing to learn from facts with mixed arity.  ...  First, they suffer from the data-sparsity issue since they can only learn from the N-ary relational data with a specific arity, i.e., parts of common N-ary relational data.  ...  To handle the data sparsity issue, we propose to partially share embeddings across arities and jointly learn embeddings from the N-ary relational data with mixed arity.  ...
