Intro

Field is a layer to define outputs of each Functional. It is very much similar to Keras' Dense layer.

It is not necessary to be defined explicitly, however, if you are expecting multiple outputs, it is better to be defined using Field. 

from sciann import Field

Fx = Field(name='Fx', units=10)

Field

sciann.functionals.field.Field(name=None, units=1, activation=<function linear at 0x7f87707bc8b0>, kernel_initializer=None, bias_initializer=None, kernel_regularizer=None, bias_regularizer=None, trainable=True, use_bias=True, dtype=None)

Configures the Field class for the model outputs.

Arguments

  • name: String. Assigns a layer name for the output.
  • units: Positive integer. Dimension of the output of the network.
  • activation: Callable. A callable object for the activation.
  • kernel_initializer: Initializer for the kernel. Defaulted to a normal distribution.
  • bias_initializer: Initializer for the bias. Defaulted to a normal distribution.
  • kernel_regularizer: Regularizer for the kernel. To set l1 and l2 to custom values, pass [l1, l2] or {'l1':l1, 'l2':l2}.
  • bias_regularizer: Regularizer for the bias. To set l1 and l2 to custom values, pass [l1, l2] or {'l1':l1, 'l2':l2}.
  • trainable: Boolean to activate parameters of the network.
  • use_bias: Boolean to add bias to the network.
  • dtype: data-type of the network parameters, can be ('float16', 'float32', 'float64').
