mindelec.architecture.FCSequential

class mindelec.architecture.FCSequential(in_channel, out_channel, layers, neurons, residual=True, act='sin', weight_init='normal', has_bias=True, bias_init='default')[source]

The dense layer sequential.

Parameters

  • in_channel (int) – The number of channels in the input space.

  • out_channel (int) – The number of channels in the output space.

  • layers (int) – The total number of layers, include input/hidden/output layers.

  • neurons (int) – The number of neurons of hidden layers.

  • residual (bool) – full-connected of residual block for the hidden layers. Default: True.

  • act (Union[str, Cell, Primitive, None]) – activate function applied to the output of the fully connected layer, eg. ‘ReLU’.Default: “sin”.

  • weight_init (Union[Tensor, str, Initializer, numbers.Number]) – The trainable weight_init parameter. The dtype is same as input x. The values of str refer to the function initializer. Default: ‘normal’.

  • has_bias (bool) – Specifies whether the layer uses a bias vector. Default: True.

  • bias_init (Union[Tensor, str, Initializer, numbers.Number]) – The trainable bias_init parameter. The dtype is same as input x. The values of str refer to the function initializer. Default: ‘default’.

Inputs:

  • input (Tensor) - Tensor of shape \((*, in\_channels)\).

Outputs:

Tensor of shape \((*, out\_channels)\).

Supported Platforms:

Ascend

Examples

>>> import numpy as np
>>> from mindelec.architecture import FCSequential
>>> from mindspore import Tensor
>>> inputs = np.ones((16, 3))
>>> inputs = Tensor(inputs.astype(np.float32))
>>> net = FCSequential(3, 3, 5, 32, weight_init="ones", bias_init="zeros")
>>> output = net(inputs).asnumpy()
>>> print(output.shape)
