}

Lookup table to store a fix number of vectors.

Params

• weight: Matrix of shape [n_embedding, d_model] initialized from a normal distribution: N(0, 1)

Fields

weight: Param<Tensor<B, 2>>

The learnable weights of the module of shape [n_embedding, d_model] initialized from a normal distribution N(0, 1).

Implementations
