This course takes a use-case-based approach to walk through the knowledge discovery and data mining process using MRS in a local compute context (on a single server).
Location: Hyderabad, India. November 28 - November 30, 2016

#About the Course
Microsoft R Server (MRS) for Analysts is designed to help analyst’s familiar with other environments migrate their knowledge of data preparation and analysis to Microsoft R Server. This course takes a use-case-based approach to walk through the knowledge discovery and data mining process using MRS in a local compute context (on a single server). This course assumes sufficient knowledge of fundamental concepts in R (as laid out by the course prerequisites), and it allows an experienced analyst (and intermediate R user) to transition to using MRS’s set of tools and capabilities for scalable big data-processing and analytics..
# Prerequisites
There are a few things you will need in order to properly follow the course materials:
* Solid understanding of R data structures (vectors, matrices, lists, data frames, environments): for example, students should confidently tell the difference between a list and a data frame, or what each object is generally a good representation for and how to subset it.
* Understanding of how to write R functions: for example, students should be able to write functions that process data in bulk (multiple columns), be able to debug functions, know how R deals with variables that are out of scope, or how to use the ellipsis to pass arguments.
* Good understanding of data manipulation and data processing in R: students should be familiar with functions such as merge, transform, subset, cbind, rbind, lapply, apply and how these functions can be used to work with a data.frame; moreover, familiarity with 3rd party packages such as dplyr is also helpful
* Good understanding of control flow and other basic programming concepts: students should know for example what loops are, and how we can use the apply family of functions to rewrite loops, be familiar with functions such as do.call, assign, etc
# Modules

8. Basic data transformations (cleaning missing values, normalizing, rescaling)
9. Passing custom transformation functions to MRS to leverage existing R code
10. Visualize, explore, and summarize data using MRS
11. Summarizing numeric data (five-point summary, correlations, histograms and line plots) and categorical data (cross-
12. tabulations and barplots)
13. Benchmarking performance on different data types (XDF vs CSV)
