• Natural Language Processing (NLP) / Spark and Sparklyr
    You down with NLP? (yeah you know me) Richard Vlasimsky with IMIDEX will demonstrate some basic natural language processing concepts and techniques in R using data from the Open Lyrics database on Github. Spark and sparklyr Sean Lopp from Rstudio will go through how to get started with Spark and sparklyr. We'll also discuss what Spark is and where its used, and demo examples of data wrangling, machine learning, and spark streaming.

  • R + TensorFlow: GPU-Accelerated Computing / data.table
    R + TensorFlow: GPU-Accelerated Computing in the Age of Deep Learning by Matt Hergott ​ Today’s complex neural networks and large data sets make it difficult or impossible to solve problems with traditional computational methods. This talk will focus on how we can use R with TensorFlow and graphics processing units (GPUs) to achieve our goals in a dramatically accelerated fashion. Topics covered include: What is GPU computing? Why do we use libraries like TensorFlow? What is the relationship between TensorFlow and Keras? What does an R + TensorFlow program look like?​ Matt Hergott focuses on traditional econometric analysis, deep learning architectures, and complex quantitative visualizations through his firm MiaBella AI. His GPU programming experience includes the emerging field of 3D holograms, and a statistical visualization package he wrote made Microsoft’s top-16 list of “noteworthy HoloLens content.” **** data.table package by David Heisler This talk provides an overview of the data.table package including a brief history of data.table, basic and some advance syntax and a comparison with dplyr. **** Talks typically start at 7:30. 7 - 7:30 is time to chat, meet new people, relax.

  • Causal Inference/ Hans Rosling's Factfulness and googleVis / R Notebooks
    CausalImpact Package Karen Kazor - Oracle Data Cloud - CausalImpact is a package contributed by the folks at Google to estimate the effect of a treatment or intervention on a individuals observed over time. In online advertising a common example is estimating additional clicks or other actions attributed to a campaign. Karen will discuss some of the ins and outs of this package. Matt Pocernich - Oracle Data Cloud Hans Rosling - Truthfulness and googleVis Inspired by Hans Rosling's book - Factfulness, I will re-visit the googleVis package which was inspired by the very cool animated plots used in his 2006 Ted Talk. This talk will illustrate some the topics from recent book using goolevis and ggplot. Question for discussion: When and why do you use R Notebooks in lieu of traditional Markdown documents?

  • R package development
    ( In case an R Meetup isn't your idea of a good way to spend Valentines Day, we bumped this meetup up a day.) Peter DeWitt will be presenting. The focus will be on reproducible reporting, documenting, and collaboration. The presentation will first show that relying on a script is insufficient for sharing code and having reproducible results. The movement from `important-analysis.R` script to an R package will be shown. Expanding on the R package structure, Peter will provide examples of when version control and continuous integration tools not only provide for higher quality documentation and work, but can be essential for keeping each developer on a team accountable. We will cover SVN and Git log and blame. Using the testthat package, and using CI.

  • Webscraping in R/ Accessing databases
    Webscraping Ryan Elmore will introduce an newish R package (ballr, pronounced baller) for scraping data from basketball-reference.com (http://basketball-reference.com/). He will highlight the use of the rvest package, along with the selectorgadget tool. He would love it if others are interested in contributing to this project! Databases in R Matt Pocernich will discuss accessing databases in R. This introductory talk will focus on accessing data using a functions found in RODBC, touch a little on dplyr, but then show how dbplyr extends dplyr to access databases.

  • Lightning Talks
    Danny Inman - NREL Using R for selecting efficient production frontiers for local sensitivity analysis. - Sean Lopps - Rstudio Group Choice (pick one) 1. RStudio 1.1 Updates (List Viewer, Databases, Terminals) 2. Turning R code into RESTful APIs 3. Intro to testthat Andy Pickering Have you every found yourself saying "It seems hotter/colder than normal lately"? I do all the time (maybe I just really like weather). Now you can check the data yourself with the WeatherComparer Shiny App. I'll show the app and talk a little about some issues I encountered when making it. Laura Kinney Metro State - discusses analyzing survey results using the tidytext package and built a shiny app evaluating Likert scale questions to measure the effectiveness of the Colorado Youth at Risk program. Peter DeWitt - Neptune A quick talk about Non Standard Evaluation with dplyr and how to move away from the (depreciated) select_, mutate_, filter_, .... functions. Ed Wolfrum - NREL Ed has been using RMarkdown to simplify reporting of data in standard formats from multiple Excel files which contain different types of analytical chemistry data that must be combined and summarized before being reported out. In this lightning talk, Ed will talk about what he has learned about using RMarkdown, and also ask for advice in improving the current workflow. Taylor Larsen is a Data Science Engineer at Health Catalyst and is part of the team responsible for healthcareai." healthcareai is an open source machine learning package developed with healthcare use cases in mind. We'll do a quick overview of healthcareai's current features, implemented use cases, and the community behind the package.
