Advanced Analytics and Machine Learning

13 - 17 Aug 2018 // Speaker: Dr. Leila Etaati

R has become a language for data analysis and machine learning hence creating a need to understand it better. Furthermore, Microsoft has introduced R server as a comprehensive platform for using machine learning and R functionality inside the data analysis tools such as SQL Server 2016 and Power BI. In this 5 days course, you will learn how to do Machine Learning in cloud using Azure ML, learn about basics of R, how to use R inside Power BI and R in SQL Server 2016.

Some of the visual from ggplot2 package will be introduced. Using the Facet chart to show 5 different variables in a chart, how to show different types of chart in facet chart, how to create slope chart just to show the difference of a variable in two dimensions (e.g. two time). How to draw a column width chart to show a bar chart with different weight, how to draw polar chart from our bar charts in different ways, how to draw a correlation chart for correlation analysis, how to draw a calendar chart, how to draw a map chart with desire sub chart in it and so on.

Create a Custom Visual chart:  The main process of how to create a custom R visual will be explained. From installing desired component to writing the code in command prompt to create a template. How to change the R files, how to change the name of chart using Jason files, how to create pbiviz file so you able to import it into Power Bi. In addition, the plotly package will be shown and how it makes the visual more interactive than before.
