You will be given a definition of a task first, then some input of the task.
In this task, you will be presented with a context from an academic paper and a question separated with a
. You have to answer the question based on the context.

For training, three types of Recurrent Neural Network (RNN) layers are used an encoder layer, a decoder layer and an output layer. These layers together form a LSTM model. LSTM is typically used in seq2seq translation.
Question: What is the architecture of the system?
Output:
seq2seq translation
