Project two – implementing an RNN for character-level language modeling in TensorFlow

Language modeling is a fascinating application that enables machines to perform human-language-related tasks, such as generating English sentences. One of the interesting efforts in this area is the work done by Sutskever, Martens, and Hinton (Generating Text with Recurrent Neural Networks, Ilya Sutskever, James Martens, and Geoffrey E. Hinton, Proceedings of the 28th International Conference on Machine Learning (ICML-11), 2011 https://pdfs.semanticscholar.org/93c2/0e38c85b69fc2d2eb314b3c1217913f7db11.pdf).

In the model that we'll build now, the input is a text document, and our goal is to develop a model that can generate new text similar to the input document. Examples of such an input can be a book or a computer program in a specific programming language.

In character-level language modeling, the input is broken down into a sequence of characters that are fed into our network one character...
