 There is a long history of [statistical language models](https://en.wikipedia.org/wiki/Language_model) in [natural language processing](https://en.wikipedia.org/wiki/Natural_language_processing), beginning with the humble [n-gram model](https://en.wikipedia.org/wiki/N-gram), which gathers statistics over a [corpus](https://en.wikipedia.org/wiki/Text_corpus) about the co-occurrence of n (1, 2, 3, 4...) words or sub-word tokens, to the [probabilistic context free grammar](https://en.wikipedia.org/wiki/Probabilistic_context-free_grammar), which imposes statistical likelihood over a pre-defined grammar, to [neural language models](https://en.wikipedia.org/wiki/Language_model#Neural_network), which harness biologically inspired [neural networks](https://en.wikipedia.org/wiki/Artificial_neural_network) in a variety of architectures to tackle the problem of language modeling.

-In addition to being an example of transfer learning for text generation, this project is also an example of the power of [React](https://reactjs.org/) and [Material-UI](https://material-ui.com/) for building modern web apps. The entire [mobile- and touch-friendly, shiny modern user interface](https://tell-me-a-story-5.herokuapp.com/) was built with fewer than 1000 lines of highly readable code. Check it out!
