LSTM

Description

Defines the weights of the LSTM layer selected by the index. Type : polymorphic.

Input parameters

 Model in : model architecture.
index : integer, index of layer.

Output parameters

 Model out : model architecture.

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].
