# CAPSTONE PROJECT DATA SCIENCE COURSERA GITHUB

This article was first published on Reimagined Invention , and kindly contributed to R-bloggers. This is a collection of notes from my learning journey that is attempt to be a cross reference between language implementations for common data science related tasks. The courses are well structured and focused on practical applications rather than on statistical theory. All probabilities for n-grams are computed with a discount smoothing strategy. You can see the analysis file, tidy dataset and codebook on Github. R-bloggers was founded by Tal Galili , with gratitude to the R community.

You will not see this message again. Therefore I have decided to include correct versions of the formulas for the model in this document. We follow exactly the same process, but this time we will pass the argument 2. This will create a unigram Dataframe, which we will then manipulate so we can chart the frequencies using ggplot.

Next, we will do the same for Bigrams, i.

rata Rda” ggplot head unigram. Python ranks 1, R at 7 in popularity. Before moving to the next step, we will save the corpus in a text file so we have it intact for future reference. This is a collection of notes from my learning journey that is attempt to be a cross reference between language implementations for common data science related tasks. Rda” ggplot head trigram. Rmd, which can be found in my GitHub repository https: In this project, I analyzed the provided dataset and created a regression model to answer questions on motor car trends.

This is available for educational purposes. This concludes the exploratory analysis. The correct definition is: Here you will find theoretical information of the model being constructed, an N-gram model with discounted smoothing and Katz backoff.

Here you can find R material that includes quizzes, assignments, exercises and my own tricks and functions that I created for courses contained in the specialization. Word Count Line Count Longest Line blogs news twitter I have completed this specialization nearly a year ago but I githuh wrote about it in detail.

I had the chance to find projects solved scidnce totally different approaches to mine and I did learn a lot from that. I am starting with the languages R and Python.

The main goal of the project is to design a Shiny application that takes as input a partial incomplete English sentence and predicts the next word in the sentence. Assumptions It is assumed that the data has been downloaded, unzipped and placed into the active R directory, maintaining the folder structure. Next, we need to load the data into R so we can start manipulating. Trigram Analysis Finally, we will follow exactly the same process for trigrams, i.

This gh-pages repository contains some additional information about the model I used for the Capstone Project of the Johns Hopkins Coursera Data Science Captsone.

In this project, I cleaned a raw data source and produced a tidy dataset. A predictive model that can recognize human activities like sitting-down and standing-up is created.

Is powered by WordPress using a bavotasan. What I did learn? The report concludes by identifying the top 10 events that cause the greatest casualties and projct monetary damage. This will create a unigram Dataframe, which we will then manipulate so we can chart the frequencies using ggplot.

This command can be used for obtaining text stats and is available on every Unix based system. Drew Conway Personal Projects Data Science Cross Reference Notes [On-going] This is a collection of notes from my learning journey that is attempt to be a cross reference between language implementations for common data science related tasks. As a next step a model will be created and integrated into a Shiny app for word prediction.

Then see Jurafsky-MartinEq. Now that we have our corpus item, we need to clean it. I did like it as I had no knowledge about Githyb, and I needed to use R to complete my thesis. These are the corrected formulas I have used for my model: Highlights — Built a multivariate linear regression model with R — Applied statistical techniques like t-tests and stepwise regression — Created a PDF report using R Markdown and knitr package.
