CPInteraction

class CPInteraction(*args, **kwargs)[source]

Bases: FunctionalInteraction[FloatTensor, FloatTensor, FloatTensor]

An implementation of the CP interaction as described [lacroix2018] (originally from [hitchcock1927]).

Note

For \(k=1\), this interaction is the same as DistMult (but consider the note below).

Note

For equivalence to CP, entities should have different representations for head & tail role. This is different to DistMult.

Initializes internal Module state, shared by both nn.Module and ScriptModule.

Attributes Summary

Methods Documentation

func(r, t)

Evaluate the Canonical Tensor Decomposition interaction function.

Parameters:

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

  • r (FloatTensor) – shape: (*batch_dims, rank, dim) The relation representations.

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

Return type:

FloatTensor

Returns:

shape: batch_dims The scores.
