RotatE
- class RotatE(*, embedding_dim=200, entity_initializer=<function xavier_uniform_>, relation_initializer=<function init_phases>, relation_constrainer=<function complex_normalize>, regularizer=None, regularizer_kwargs=None, **kwargs)[source]
Bases:
pykeen.models.nbase.ERModelAn implementation of RotatE from [sun2019].
RotatE models relations as rotations from head to tail entities in complex space:
\[\textbf{e}_t= \textbf{e}_h \odot \textbf{r}_r\]where \(\textbf{e}, \textbf{r} \in \mathbb{C}^{d}\) and the complex elements of \(\textbf{r}_r\) are restricted to have a modulus of one (\(\|\textbf{r}_r\| = 1\)). The interaction model is then defined as:
\[f(h,r,t) = -\|\textbf{e}_h \odot \textbf{r}_r - \textbf{e}_t\|\]which allows to model symmetry, antisymmetry, inversion, and composition.
