Multi-channel LSTM Network Keras wih TensorFlow Utilize the CloVe and FastText Skipgram pretrained embeddings, allows he underlying network to access larger feature space to build complex features on top of.

Can use utilize combinations of vaious corpus and embedding methods for better performance

Bidirectional LSTM network is used o encode seuential information on the embedding layers.
