TransHInteraction

class TransHInteraction(p, power_norm=False)[source]

Bases: NormBasedInteraction[FloatTensor, Tuple[FloatTensor, FloatTensor], FloatTensor]

A stateful module for the TransH interaction function.

Initialize the norm-based interaction function.

Parameters
  • p (int) – The norm used with torch.linalg.vector_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.

Parameters
  • h (FloatTensor) – shape: (*batch_dims, dim) The head representations.

  • w_r (FloatTensor) – shape: (*batch_dims, dim) The relation normal vector representations.

  • d_r (FloatTensor) – shape: (*batch_dims, dim) The relation difference vector representations.

  • t (FloatTensor) – shape: (*batch_dims, dim) The tail representations.

  • p (int) – The p for the norm. cf. torch.linalg.vector_norm().

  • power_norm (bool) – Whether to return \(|x-y|_p^p\).
