TimeDistributed(layer)

Bidirectional(layer, merge_mode = "concat")

`layer`	a layer instance (must be a recurrent layer for the bi-directional case)
`merge_mode`	Mode by which outputs of the forward and backward RNNs will be combined. One of 'sum', 'mul', 'concat', 'ave', None. If None, the outputs will not be combined, they will be returned as a list.
