TARDIS

Tardis stands for Time And Relative Dimension In Space. Yes, it is the TARDIS from Dr. Who.

Did I mention the TARDIS looks like a BLEU telephone box. Oops, I meant blue telephone box.

We have switched to use cudnn, updated code will be made available soon.

Features

• Standard Seq2seq model (we won't update this for now)
• Seq2seq with attention
• Fast LSTM/GRU
• Bilinear/Dot attention mechanism
• Hard Attention (using REINFORCE update rule)

Code Organization

The code is organized as follow

• src/core Contains core modules, such as fast LSTM, GRU, MemoryBlock, ... These are building units of more complicated models,
• src/seq2seq Neural machine translation modules,
• src/data Data processing scripts, to create/load bitext or monolingual data,
• src/misc some ultility functions
• src/tardis search engine, probably should rename to search
• src/test unit tests

Planing

• Recurrent Memory Networks (in progress)
• Character LSMT models
• REINFORCE training NMT (in progress)
• Efficient padding/bucketting sentences to speed up training
