Welcome to Text Recovery Project 👋

A python library for training a Transformer neural network to solve the Running Key Cipher, widely known in the field of cryptography.

🚀 Objective

The main goal of the project is to study the possibility of using Transformer neural network to “read” meaningful text in columns that can be compiled for a Running Key Cipher. You can read more about the problem here.

In addition, the second rather fun 😅 goal is to train a large enough model so that it can handle the case described below. Let there be an original sentence:

Hello, my name is Zendaya Maree Stoermer Coleman but you can just call me Zendaya.

The columns for this sentence will be compiled in such a way that the last seven contain from ten to thirteen letters of the English alphabet, and all the others from two to five. Thus, the last seven characters will be much harder to "read" compared to the rest. However, we can guess from the meaning of the sentence that this is the name Zendaya. In other words, the goal is also to train a model that can understand and correctly “read” the last word.

⚙ Installation

Trecover requires Python 3.8 or higher and supports both Windows and Linux platforms.

1. Clone the repository:

git clone https://github.com/alex-snd/TRecover.git  && cd trecover

2. Create a virtual environment:

   • Windows:

   python -m venv venv
   

   • Linux:

   python3 -m venv venv
   

3. Activate the virtual environment:

   • Windows:

   venv\Scripts\activate.bat
   

   • Linux:

   source venv/bin/activate
   

4. Install the package inside this virtual environment:

   • Just to run the demo:

   pip install -e ".[demo]"
   

   • To train the Transformer:

   pip install -e ".[train]"
   

   • For development and training:

   pip install -e ".[dev]"
   

5. Initialize project's environment:

   trecover init
   

   For more options use:

   trecover init --help
   

👀 Demo

• 🤗 Hugging Face
  You can play with a pre-trained model hosted here.
• 🐳 Docker Compose
  
  • Pull from Docker Hub:

    docker-compose -f docker/compose/scalable-service.yml up

  • Launch the service:

    trecover up
    

🗃️ Data

The WikiText and WikiQA datasets were used to train the model, from which all characters except English letters were removed.
You can download the cleaned dataset:
