This Param Object is specifically used for SequenceMask
n-dimensional input array of the form [max_sequence_length, batch_size, other_feature_dims] where n>2
vector of sequence lengths of the form [batch_size]
The sequence axis. Only values of 0 and 1 are currently supported.
If set to true, this layer takes in an extra input parameter sequence_length to specify variable length sequence
The value to be used as a mask.
