Vivian Zhang(VZ) -
SupStat was born in 2012 out of the collaboration of 60+ individuals(Statistician, Computer Engineers, Mathematician,Professors, graduate students and talend Data genius)who met through a well-known non-profit organization in China, Capital of Statistics. The SupStat team met through various collaborations on R packages and analytic work. In 2013, SupStat became involved in the New York City data science community through hosting the NYC Open Data Meetup, and soon began offering formal courses through the NYC Data Science Academy. SupStat offers consulting services in the areas of R development, data visualization, and big data solutions. We are experienced with many technologies and languages including R, Python, Hadoop, Spark, Node.js, etc. Courses offered include Data Science with R (Beginner, Intermediate), Data Science with Python (Beginner, Intermediate), and Hadoop (Beginner, Intermediate), as well as many targeted courses on R packages and data visualization tools.
Allen and I, the two co-founders, have been passionate about Data Mining since a young age (we talked about it back in 1997). With industry experience as Chief Data scientist/Senior Analyst and a spirit of entrepreneurship, we started the firm by gathering all the top R/Hadoop/D3.js programmers we knew.

June 2012, Established in Beijing
July 2012, Offered R intensive Bootcamp in Beijing to 50+ college students
June 2013, Established in NYC
Nov 2013, Launched our NYC training brand: NYC Data Science Academy
Jan 2014, Became premium partner of Revolution Analytics in China
Feb 2014, Became training and reseller partner of RStudio in US and China
April 2014, Became Exclusive reseller partner of Transwarp in US
Started to offer R built-in and professional services for Hadoop/Spark
May 2014, Organized and sponsored R conference in Beijing
NYC Open Data Meetup had 1800+ members in one year
Jun 2014, Sponsored UCLA R conference (Vivian was panelist for female R programmer talk.)
The major turning point was in November, 2013, when we decided to start our NYC office and launched the NYC Data Science Academy.
We are committed to helping our clients make distinctive, lasting and substantial improvement in their performance, sales, clients and employee satisfaction by fully utilizing data. We are a value-driven firm. For us this means:

Applying a structured problem-solving approach where all options are considered, researched, and analyzed carefully before recommendations are made
Our Vision: Be a firm that attracts exceptional people to meet the growing demand for data analysis and visualization.
With engaged clients, we want to share the excitement, unlimited potential and methodologies of using data to create business value. We want to be the go-to firm when people think of getting data analytic training, consulting, and big data products.
With top data scientists, we want to be the home for those who want different data challenges all the time. We promote their open data/demo work in the community and expand the impact of the analytic tools and methodologies they developed. We connect the best ones to build the strongest team.
With new college students and young professionals, we want to help them succeed and be able to handle real world problems right away though our short-term, intensive training programs and internship programs. Through our rich experience, we have tailored our training program to solve some of the critical problems people face in their workplace.
Through our partnerships we want to spread the best technologies between the US and China. We want to close the gap and bring solutions and offerings to clients we serve. We are at the frontline to pick what is the best product for our clients.
We are glad we have the opportunity to do what we love and are good at, and will continue to enjoy doing it with a growing and energetic team.
DS -What is the state of open source statistical software in China? How have you contributed to R in China and how do you see the future of open source evolve there?
VZ- People love R and embrace R. In May 2014, We helped to organize and sponsor the R conference in Beijing, with 1400 attendants. See our blog post for more details: http://www.r-bloggers.com/the-7th-china-r-conference-in-beijing/
We have helped organize two R conferences in China in the past year, Spring in Beijing and Winter in Shanghai. And we will do a Summer R conference in Guangzhou this year. That’s three R conferences in one year!
DS- Describe some of your work with your partners in helping sell and support R in China and USA
VZ- Revolution Analytics and RStudio are very respected in the R community. We are glad to work and learn from them through collaboration.
With Revolution, we provide services to do proof-of-concept and professional services including analytics and visualization. We also sell Revolution products and licenses in China. With RStudio, we sell Rstudio Server Pro and Shiny and promote training programs around those products in NYC. We plan to sell these products in China starting this summer. With Transwarp, we offer the best R analytic and paralleling experience through the Hadoop/Spark ecosystem.
DS- You have done many free workshops in multiple cities. What has been the response so far.
VZ- Let us first talk about what happened in NYC.
I went to a few meetups before I started my own meetup group. Most of the presentation/talks were awesome but they were not delivered and constructed in a way that attendants could learn and apply the technology right away. Most of the time, those events didn’t offer source code or technical details in the slides.
When I started my own group, my goal was “whatever cool stuff we showed you, we will teach you how to do it.” The majority of the events were designed as hands-on workshops while we hosted a few high profile speakers’ talks from time to time (including the chief data science scientist for the Obama Campaign).
My workshops cover a wide range of topics, including R, Python, Hadoop, D3.js, data processing, Tableau, location data query, open data, etc. People are super excited and keep saying “oh wow oh wow”, “never thought that I could do it”, ”it is pretty cool.” Soon our attendants started giving back to the group by teaching their skills and fun projects, offering free conference room, and sponsoring pizzas.
We are glad we have built a community of sharing experience and passion for data science. And I think this is a very unique thing we can do in NYC (due to the fact everything is close to half-hour subway distance). We host events 2-3 times per week and have attracted 1900 members in one year.
In other cities such as Shanghai and Beijing, we do free workshops for college students and scholars every month. We promise to go to the colleges as far as within 24 hours distance by train from Beijing. Through partnerships with Capital of Statistics and DataUnion, we hosted entrepreneur sharing events with devoted speeches and lighting talks.
In NYC, we typically see 15 to 150 people per event. U.S. sponsors have included McKinsey & Company, Thoughtworks, and others. Our Beijing monthly tech event sees over 500 attendees and gains attraction from event co-hosts including Baiyu, Youku and others.
DS- What are some interesting projects of Supstat that you would like to showcase.
VZ- Let me start with one interesting open data project on Citibike data done by our team. The blog post, slides and meetup videos can be found at http://nycdatascience.com/meetup/nyc-open-data-project-ii-my-citibike/
Citibike provides a public bike service. There are many bike stations in NYC. People want to take a bike from a station with at least one available bike. And when they get to the destination, they want to return their bike to a station with at least one available slot. Our goal was to predict where to rent and where to return Citibikes. We showed the complete workflow including data scraping, cleaning, manipulation, processing, modeling, and making algorithms into a product.
We built a program to scrape data and save it to our database automatically. Using this data we utilized models from time series theory and machine learning to predict bike numbers in all the stations. Based on the models, we built a website for this citibike system. This application helps users of citibike arrange their trips better. We also showed a few tricks such as how to set up cron job on Linux, Windows and Mac machines, and how to get around RAM limitations on servers with PostgreSQL.
We’ve done other projects in China using R to solve problems ranging from Telecommunications data caching to Cardiovascular disease prevention. Each of these projects has required a unique combination of statistical knowledge and data science tools, with R being the backbone of the solution.
