Training Char-RNN with The Count of Monte Cristo

📅 2015-Jul-08 ⬩ ✍️ Ashwin Nanjappa ⬩ 🏷️ char-rnn, lua, torch ⬩ 📚 Archive

Andrej Karpathy recently shared an interesting article about the capabilities of Recurrent Neural Networks here. He also shared an open-source character-level RNN named char-rnn that is easy to train with some text. Lots of people have had fun training it and seeing what it can produce! 😊

Installation of Torch and char-rnn is straightforward. Just follow the instructions and it should be done.

char-rnn needs a large amount of text to train and I used the massive 1500-page tome The Count of Monte Cristo which I read recently. The English translation of this book is available at Project Gutenberg here as a text file. I cropped off the Gutenberg-related text at the beginning and end of this file and trained the char-rnn with it.

With a low temperature, char-rnn returned text which was almost correct in grammar and spelling. However, since I have read the book, I noticed that it played safe, seeming like a nonsense regurgitation of the book:

to the count's steward, and the count was still as the door of the stranger to the
present of the count's power of the two features of the count's shoulders.

who had been so far as the door of his father's servant, who was still as the
countenance of the count with a smile of the procureur. "I am already said that the count was the

High temperature was more fun! There was more interesting and new conversations, more newly created phrases, but also more spelling mistakes. You can read it below and enjoy: 😊
