These frequency tables currently need to be reduced in project in order to make them feasible for an on-line shiny app where speed of prediction is a significant factor and the size of the app is a significant consideration. I needed swiftkey teach myself a project amount of new concepts regarding n-grams, smoothing, Katz backoff models, and developing holdout data for text models. Next Steps This concludes the exploratory analysis. Assumptions It is assumed that the data has been downloaded, unzipped and placed into the active R directory, maintaining the folder structure. This report meets the following requirements:.

The project size of the words indicate how often the terms occur in the document with respect to one another. This Rmarkdown report describes exploratory analysis of the sample training data set and summarizes plans for creating the prediction model. This report meets the following requirements:. The app will process profanity in order to predict the next word but will not present profanity as a prediction. Future Plan Create an Ngram Table of unigrams, bigrams, and trigrams with preprocessed clarion nursing essay unigrams, and a word frequency column to sort the most reliable predictions.
