This interface is used to construct a callable object of the ``FC`` class.
For more details, refer to code examples.
It creates a fully connected layer in the network. It can take
one or multiple ``Tensor`` as its inputs. It creates a Variable called weights for each input tensor,
which represents a fully connected weight matrix from each input unit to
each output unit. The fully connected layer multiplies each input tensor
with its corresponding weight to produce an output Tensor with shape [N, `size`],
where N is batch size. If multiple input tensors are given, the results of
multiple output tensors with shape [N, `size`] will be summed up. If ``bias_attr``
is not None, a bias variable will be created and added to the output.
Finally, if ``act`` is not None, it will be applied to the output as well.
When the input is single ``Tensor`` :
.. math::
Out = Act({XW + b})
When the input are multiple ``Tensor`` :
.. math::
Out = Act({\sum_{i=0}^{N-1}X_iW_i + b})
In the above equation:
* :math:`N`: Number of the input. N equals to len(input) if input is list of ``Tensor`` .
* :math:`X_i`: The i-th input ``Tensor`` .
* :math:`W_i`: The i-th weights matrix corresponding i-th input tensor.
* :math:`b`: The bias parameter created by this layer (if needed).
* :math:`Act`: The activation function.
* :math:`Out`: The output ``Tensor`` .
See below for an example.
.. code-block:: text
Given:
data_1.data = [[[0.1, 0.2]]]
data_1.shape = (1, 1, 2) # 1 is batch_size
data_2.data = [[[0.1, 0.2, 0.3]]]
data_2.shape = (1, 1, 3) # 1 is batch_size
fc = FC("fc", 2, num_flatten_dims=2)
out = fc(input=[data_1, data_2])
Then:
out.data = [[[0.182996 -0.474117]]]
out.shape = (1, 1, 2)
Parameters:
name_scope(str): The name of this class.
size(int): The number of output units in this layer.
num_flatten_dims (int, optional): The fc layer can accept an input tensor with more than
two dimensions. If this happens, the multi-dimension tensor will first be flattened
into a 2-dimensional matrix. The parameter `num_flatten_dims` determines how the input
tensor is flattened: the first `num_flatten_dims` (inclusive, index starts from 1)
dimensions will be flatten to form the first dimension of the final matrix (height of
the matrix), and the rest `rank(X) - num_flatten_dims` dimensions are flattened to
form the second dimension of the final matrix (width of the matrix). For example, suppose
`X` is a 5-dimensional tensor with a shape [2, 3, 4, 5, 6], and `num_flatten_dims` = 3.
Then, the flattened matrix will have a shape [2 x 3 x 4, 5 x 6] = [24, 30]. Default: 1
param_attr (ParamAttr or list of ParamAttr, optional): The parameter attribute for learnable
weights(Parameter) of this layer. Default: None.
bias_attr (ParamAttr or list of ParamAttr, optional): The attribute for the bias
of this layer. If it is set to False, no bias will be added to the output units.
If it is set to None, the bias is initialized zero. Default: None.
act (str, optional): Activation to be applied to the output of this layer. Default: None.
is_test(bool, optional): A flag indicating whether execution is in test phase. Default: False.
dtype(str, optional): Dtype used for weight, it can be "float32" or "float64". Default: "float32".
Attribute:
**weight** (list of Parameter): the learnable weights of this layer.
**bias** (Parameter or None): the learnable bias of this layer.
Returns:
None
