ConvLSTM2D

Description

Defines the weights of the ConvLSTM2D layer selected by the index. Type : polymorphic.

 

Input parameters

 

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

conv_lstm_2d_weight : cluster

kernel : array, 4D values. kernel = [4*n_filters, channels, size[0], size[1]].
recurrent_kernel : array, 4D values. recurrent_kernel = [4*n_filters, n_filters, size[0], size[1]].
bias : array, 1D values. bias = [4*n_filters].

Output parameters

 

Β Model out :Β model architecture.

Dimension

  • kernel = [4*n_filters, channels, size[0], size[1]]

The kernel size depends on the input of the ConvLSTM2D layer and the parameters n_filters and size of the ConvLSTM2D cell.
For example, if the input of the layer has a size of [samples = 10, time = 8, channels = 5, rows = 3, cols = 2], n_filters a value of 6 and size the value [3, 3], then kernel will have a size of [4*n_filters = 6, channels = 5, size[0] = 3, size[1] = 3].

 

  • recurrent_kernel = [4*n_filters, n_filters, size[0], size[1]]

The size of recurrent_kernel depends on the parameters n_filters and size of the ConvLSTM2D cell.
For example, if n_filters has a value of 6 and size the value [3, 3], then recurrent_kernel will have a size of [4*n_filters = 6, n_filters = 6, size[0] = 3, size[1] = 3].

 

  • bias = [4*n_filters]

The size of bias depends on the parameter n_filters of the ConvLSTM2D cell.
For example if n_filters has a value of 6 then the bias size will be [4*n_filters = 6].
