RNN encoder-decoder model keeps overfitting
i've trainning a machine translation model (from english to vietnamese) with RNN, LSTM with 25000 example pairs (for training set -> 20000, test set -> 5000) the model i used like below but val_acc always reach to ~0,37 and does not increment…

Re-encoding a context vector after every step of decoding?
I am currently working on a sequence model which aims to predict the head orientation of somebody watching VR for an arbitrary amount of frames in the future.
Using an encoder-decoder paradigm, a person's previous 100 frames of head orientation and…

How to build a decoder using dynamic rnn in Tensorflow?
I know how to build an encoder using dynamic rnn in Tensorflow, but my question is how can we use it for decoder?
Because in decoder at each time step we should feed the prediction of previous time step.
Thanks in advance!
