Seq2VecEncoder#
class Seq2VecEncoder(_EncoderBase, Registrable)
A Seq2VecEncoder
is a Module
that takes as input a sequence of vectors and returns a
single vector. Input shape : (batch_size, sequence_length, input_dim)
; output shape:
(batch_size, output_dim)
.
We add two methods to the basic Module
API: get_input_dim()
and get_output_dim()
.
You might need this if you want to construct a Linear
layer using the output of this encoder,
or to raise sensible errors for mis-matching input dimensions.
get_input_dim#
class Seq2VecEncoder(_EncoderBase, Registrable):
| ...
| def get_input_dim(self) -> int
Returns the dimension of the vector input for each element in the sequence input
to a Seq2VecEncoder
. This is not
the shape of the input tensor, but the
last element of that shape.
get_output_dim#
class Seq2VecEncoder(_EncoderBase, Registrable):
| ...
| def get_output_dim(self) -> int
Returns the dimension of the final vector output by this Seq2VecEncoder
. This is not
the shape of the returned tensor, but the last element of that shape.
