How to Put your Meetup on the Map (Literally)

This meetup, we go back to our roots!!! We will discuss an application of R programming, involving visualization, maps, optimization and reporting, using data from meetup.com.

We are excited to welcome our member, and Data Community DC Co-Founder and President Dr. Harlan Harris to talk about a project he has been working on with Alan Briggs.

ABSTRACT:
Meetup organizers have to face a problem that's common to many other organizations. Where should I put my event, or factory, or chain of convenience stores, or cell phone tower? You could pay consultants many thousands of dollars to give you recommendations, or you can figure it out over a weekend using R! In this presentation, we use home and work ZIP codes that Data Community DC collected from Meetup attendees to solve two location analysis problems: What is the best single location for one of our Meetup events? What are the best 3 locations that are convenient for everyone at least sometimes? Techniques that will be discussed include: working with latitude/longitude data, constructing geometric cost functions, mapping, continuous optimization, global optimization, and dynamic report generation. R packages used include: knitr, plyr, reshape2, ggplot2, ggmap, and DEoptim.

SPEAKER BIOS:
Harlan Harris has a PhD in Computer Science (Machine Learning) from the University of Illinois at Urbana-Champaign, and postdoctoral research experience in experimental psychology and cognitive science. He currently works as a solutions architect for Sentrana, Inc., in Washington, DC. Harlan is the co-founder and co-organizer of the Data Science DC Meetup, is the co-founder and President of Data Community DC, and recently wrote a short e-book about data scientists called "Analyzing the Analyzers".

    My walkthrough is here: http://harlanh.github.io/loc-opt-demo/loc-opt-demo.html There's a GitHub link at the top if you'd like to pull the source (Rmarkdown) and data and play with it! I'll get Alan's slides up presently...

    Great to see everyone!

    The PhD meetup delivers top content once again; thanks, Harlan! I would only hope Harlan would consider a few more iterations of his statistics, including subsets of the attendee data such as New Attendees, People who attend 2 | 4 | 6 | 8 times per year, people who attend 2 | 3 | 4 times in a row, etc. Likewise, you might want to consider whether time of year or topic is as big a determining factor as location. Plenty of work left to do on this one.

    Not going to be able to make it (traveling from the office in Springfield). Is the content going to be available online?

    Is this the same as "Learn. Network. Do." at: http://www.meetup.com/INFORMS-Maryland/events/138220312/ ???
