Transformation of objective function of Knowledge Graph Representation Learning
I am currently reading a paper about Negative Sampling in Knowledge Graphs, and ran into the objective function of KG Representation Learning.
There are 2 nodes $u, v$ which composes a triple. And there are negative samples of $u$ given $v$, denoted…
