Multi-channel LSTM Network Keras wih TensorFlow Utilize the GloVe 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 various corpus and embedding methods for better performance
Bidirectional LSTM network is used o encode sequential information on the embedding layers.
Dense layer to project fnal output classification
Use embedding... embeddings = transfer learning
? CNN vs BI-LSTM (RNN) this approach, BI-LSTM does not need a lot of data
Attention mechanism -- translate ... you can look back
... not a fixed vector size
