RNN (LSTM)

Description

Gets the weights of the RNN layer selected by the name. Type : polymorphic.

 

Input parameters

 

 Model in : model architecture.
 name : stringname of layer.

 

Output parameters

 

 Model out : model architecture.

 weights_info : cluster

 index : integer, index of layer.
 name : string, name of layer.
 weights : cluster

 input_weights : array, 2D values. input_weights = [features, 4*units].
 hidden_weights : array, 2D values. hidden_weights = [units, 4*units].
biases : array, 1D values. biases = [4*units].

Dimension

  • input_weights = [features, 4*units]

The size depends on the LSTM layer input and the units parameter.
For example, if the input has a size of [batch = 10, timesteps = 8, features = 5] and units a value of 3 then input_weights will have a size of [features = 5, 4*units = 3].
Another example, if the input has a size of [batch = 15, timesteps = 8, features = 6] and units a value of 2 then input_weights will have a size of [features = 6, 4*units = 2].

 

  • hidden_weights = [units, 4*units].

The size depends on the units parameter of the LSTM layer.
For example, if units has a value of 6 then hidden_weights will have a size of [units = 6, 4*units = 6].
Another example, if units has a value of 3 then hidden_weights will have a size of [units = 3, 4*units = 3].

 

  • biases = [4*units]

The size depends on the units parameter of the LSTM layer.
For example, if units has a value of 6, then biases will have a size of [4*units = 6].
Another example, if units has a value of 3, then biases will have a size of [4*units = 3].
