TransRInteraction

class TransRInteraction(p, power_norm=True)[source]

Bases: pykeen.nn.modules.TranslationalInteraction[torch.FloatTensor, Tuple[torch.FloatTensor, torch.FloatTensor], torch.FloatTensor]

A stateful module for the TransR interaction function.

See also

pykeen.nn.functional.transr_interaction()

Initialize the translational interaction function.

Parameters

  • p (int) – The norm used with torch.norm(). Typically is 1 or 2.

  • power_norm (bool) – Whether to use the p-th power of the L_p norm. It has the advantage of being differentiable around 0, and numerically more stable.
