mindelec.architecture.LinearBlock

class mindelec.architecture.LinearBlock(in_channels, out_channels, weight_init='normal', bias_init='zeros', has_bias=True, activation=None)

The LinearBlock. Applies a linear transformation to the incoming data.

Parameters

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

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

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

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

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

• activation (Union[str, Cell, Primitive, None]) – activate function applied to the output of the fully connected layer. Default: None.

Inputs:

• input (Tensor) - Tensor of shape $(\ast ,in\mathrm{\_}channels)$.

Outputs:

Tensor of shape $(\ast ,out\mathrm{\_}channels)$.

Supported Platforms:

Ascend

Examples

>>> import numpy as np
>>> from mindelec.architecture import LinearBlock
>>> from mindspore import Tensor
>>> input = Tensor(np.array([[180, 234, 154], [244, 48, 247]], np.float32))
>>> net = LinearBlock(3, 4)
>>> output = net(input)
>>> print(output.shape)
(2, 4)
