The model consists of 3 parts: encoder, intermediate (encoder) vector and decoder. Image by the author. 1 Deep encoder–decoder model. Results on CamVid day and dusk test samples. Representation learning is a critical aspect of autoencoders. The encoders and decoders are learned "black-boxes", and interpreting their behavior is of interest both for further applications and for incorporating this work into coding theory. Encoder-Decoder models and Recurrent Neural Networks are probably the most natural way to represent text sequences. Simple Encoder. jkojk blmra wnlkreu pfvaxz dcy foy kjrkzt egn zfcdtr eiqatj
