 ============
 We implement a **Deep Character-Level Neural Machine Translation By Learning Morphology** based on [Theano](https://github.com/Theano/Theano) and [Blocks](https://github.com/mila-udem/blocks). Please intall relative packages according to [Blocks](http://blocks.readthedocs.io/en/latest/setup.html) before testing our program. Note that, please use Python 3 instead of Python 2. There will be some problems with Python 2. 
 
-It is an improved version of [DCNMT](https://github.com/swordyork/dcnmt/tree/old-version), the architecture of DCNMT is shown in the following figure which is a single, large neural network. Please refer to the paper for the details.
