Big Data Predictive Analytics with Revolution R Enterprise (Gartner BI Summit...Revolution Analytics
Presented by David Smith, Chief Community Officer, Revolution Analytics at Garner Business Intelligence and Analytics Summit, April 2014.
In this presentation, I'll introduce the open source R language — the modern standard for Data Science — and the enhanced performance, scalability and ease-of-use capabilities of Revolution R Enterprise. Customer case studies will illustrate Revolution R Enterprise as a component of the real-time analytics deployment process, via integration with Hadoop, database warehousing systems and Cloud platforms, to implement data-driven end-user applications.
This session will demonstrate how the all-star line-up featuring R and Storm enables real-time processing on massive data sets; a real home run! The presenters will use actual baseball data and a real-world use case to compose an implementation of the use case as Storm components (spouts, bolts, etc.) and highlight how R can be an effective tool in prototyping a solution. Attendees will leave the session with information that could easily be applied for other use cases such as video game analytics, fraud detection, intrusion detection, and consumer propensity to buy calculations.
The business need for real-time analytics at large scale has focused attention on the use of Apache Storm, but an approach that is sometimes overlooked is the use of Storm and R together. This novel combination of real-time processing with Storm and the practical but powerful statistical analysis offered by R substantially extends the usefulness of Storm as a solution to a variety of business critical problems. By architecting R into the Storm application development process, Storm developers can be much more effective. The aim of this design is not necessarily to deploy faster code but rather to deploy code faster. Just a few lines of R code can be used in place of lengthy Storm code for the purpose of early exploration – you can easily evaluate alternative approaches and quickly make a working prototype.

Analysts predict that the Hadoop market will reach $50.2 billion USD by 2020.1 Applications driving these large expenditures are some of the most important workloads for businesses today including:
• Analyzing clickstream data, including site-side clicks and web media tags. • Measuring sentiment by scanning product feedback, blog feeds, social media comments, and Twitter streams. • Analysis of behavior and risk by capturing vehicle telematics. • Optimizing product performance and utilization by gathering data from built-in sensors. • Tracking and analyzing people and material movement with location-aware systems. • Identifying system performance and intrusion attempts by analyzing server and network log. • Enabling automatic document and speech categorization. • Extracting learning from digitized images, voice, video, and other media types.
Predictive analytics on large data sets provides organizations with a key opportunity to improve a broad variety of business outcomes, and many have embraced Apache Hadoop as the platform of choice.
In the last few years, large businesses have adopted Apache Hadoop as a next-generation data platform, one capable of managing large data assets in a way that is flexible, scalable, and relatively low cost. However, to realize predictive benefits of big data, organizations must be able to develop or hire individuals with the requisite statistics skills, then provide them with a platform for analyzing massive data assets collected in Hadoop “data lakes.”
As users adopted Hadoop, many discovered performance and complexity limited Hadoop’s use for broad predictive analytics use. In response, the Hadoop community has focused on the Apache Spark platform to provide Hadoop with significant performance improvements. With Spark atop Hadoop, users can leverage Hadoop’s big-data management capabilities while achieving new performance levels by running analytics in Apache Spark.
What remains is a challenge—conquering the complexity of Hadoop when developing predictive analytics applications.
In this white paper, we’ll describe how Microsoft R Server helps data scientists, actuaries, risk analysts, quantitative analysts, product planners, and other R users to capture the benefits of Apache Spark on Hadoop by providing a straightforward platform that eliminates much of the complexity of using Spark and Hadoop to conduct analyses on large data assets.
[Presented to the 7th China R Users Conference, Beijing, May 2014.]
Adoption of the R language has grown rapidly in the last few years, and is ranked as the number-one data science language in several surveys. This accelerating R adoption curve has been driven by the Big Data revolution, and the fact that so many data scientists — having learned R at university — are actively unlocking the secrets hidden in these new, vast data troves.
In more than 6 years of writing for the Revolutions blog, I’ve discovered hundreds of applications of R in business, in government, and in the non-profit sector. Sometimes the use of R is obvious, and sometimes it takes a little bit of detective work to learn how R is operating behind the scenes. In this talk, I’ll begin by presenting some recent statistics on the growth of R. Then I’ll recount some of my favourite applications of R, and show how R is behind some amazing innovations in today’s world.

Since the acquisition of Revolution Analytics in April 2015, Microsoft has embarked upon a project to build R technology into many Microsoft products, so that developers and data scientists can use the R language and R packages to analyze data in their data centers and in cloud environments.
In this talk I will give an overview (and a demo or two) of how R has been integrated into various Microsoft products. Microsoft data scientists are also big users of R, and I'll describe a couple of examples of R being used to analyze operational data at Microsoft. I'll also share some of my experiences in working with open source projects at Microsoft, and my thoughts on how Microsoft works with open source communities including the R Project.

What is R and how useful is it for datajournalism? Isn't Excel enough? And how do you use R anyway?
This new School of Data skillshare by David Opoku will help you understand how R fits into the data pipeline and introduce you to the basics of using the software.
R is more than just a language. Many of the reasons why R has become such a popular tool for data science come from the ecosystem surrounding the R project. R users benefit from the many resources and packages created by the community, while commercial companies (including Microsoft) provide tools to extend and support R, and services to help people use R.
In this talk, I will give an overview of the R Ecosystem and describe how it has been a critical component of R’s success, and include several examples of Microsoft’s contributions to the ecosystem.

users of data
● Geared toward the power-user who has to work with large amounts
of data while avoiding coding as much as practically possible
● Why is it called R ???
● the co-creators were Ross & Robert!
● it was trendy to give languages letter names (B, C, S, etc)
● As R becomes more mainstream, it may have everyday applications
for people in roles requiring them to work with or 'be in the data'
9. R – What can it be used for?
● For presenting & solving data-oriented problems
● Exploratory Analysis
● discovering data about the data
● clustering & visualizing data
● quickly building summaries of the data being worked with
● Wrangling/Munging & re-shaping data

● score is a function of median household income and education level
● Top 5% are deemed the 'SuperZIPs'
● click to see the R + shiny powered Interactive data map
11. Recap & Resources
● R is an open-source environment that can be used for complex Data
'work'
● essential part of a Data Scientist's Toolbox
● Also a functional programming language
● can be used to create programs to automate routine, repetitive data
tasks and for general software development
● Becoming a mainstream tool
● benefiting from increased commercial support
● maturing ecosystem of Packages
● Agility, flexibility, growing talent pool, & low cost of ownership all a
part of R's appeal
