ConvLSTM2D

class ConvLSTM2D[T] extends KerasLayer[Tensor[T], Tensor[T], T]

Convolutional LSTM. Data format currently supported for this layer is 'CHANNEL_FIRST' (dimOrdering='th'). Border mode currently supported for this layer is 'same'. The convolution kernel for this layer is a square kernel with equal strides 'subsample'. The input of this layer should be 5D.

When using this layer as the first layer in a model, you need to provide the argument inputShape (a Single Shape, does not include the batch dimension).

T

The numeric type of parameter(e.g. weight, bias). Only support float/double now.

    This function returns a table contains ModuleName, the parameter names and parameter value in this module.

    For example, get the weight of a module named conv1: table[Table]("conv1")[Tensor[T]]("weight").

    The names of the parameters follow such convention:

    1. If there's one parameter, the parameter is named as "weight", the gradient is named as "gradWeight"

    2. If there're two parameters, the first parameter is named as "weight", the first gradient is named as "gradWeight"; the second parameter is named as "bias", the seconcd gradient is named as "gradBias"

    3. If there're more parameters, the weight is named as "weight" with a seq number as suffix, the gradient is named as "gradient" with a seq number as suffix

    Custom modules should override this function the default impl if the convention doesn't meet the requirement.
