I have been working on LSTM for timeseries forecasting by using tensorflow. Now, i want to try sequence to sequence (seq2seq). In the official site there is a tutorial which shows NMT with embeddings . So, how can I use this new seq2seq module without embeddings? (directly using time series "sequences").
# 1. Encoder
encoder_cell = tf.contrib.rnn.BasicLSTMCell(LSTM_SIZE)
encoder_outputs, encoder_state = tf.nn.static_rnn(
encoder_cell,
x,
dtype=tf.float32)
# Decoder
decoder_cell = tf.nn.rnn_cell.BasicLSTMCell(LSTM_SIZE)
helper = tf.contrib.seq2seq.TrainingHelper(
decoder_emb_inp, decoder_lengths, time_major=True)
decoder = tf.contrib.seq2seq.BasicDecoder(
decoder_cell, helper, …
