Machine Learning with R
Self-paced Online Course
A programming language for statistical computing, R is one most widely used software environments for computational statistics, data science and visualisation. Millions of analysts and data scientists use R for problems ranging from quantitative finance and computational biology to market research and behavioural studies. Though a freeware, recent surveys show that the adoption of R is fast outpacing legacy, proprietary data analysis software, which continue to lag behind it in features and functionalities.
Who is this course for?
This is a course meant to introduce you to Machine Learning techniques such as Decision tree, Logistic Regression, Naive Bayes, Clustering, etc as well as a fundamental introduction to R programming. If you are unfamiliar with machine learning or you want to implement in your area of work, then this course is for you. The course provides elaborate explanation of the concepts, and other necessary techniques in R for beginners.
Why this course?
Machine Learning is a method of data analysis that automates analytical model building.
It is also a branch in computer science. The tasks in machine learning viz logistic regression,
clustering, decision tree are widely used in different field of studies.
It is equally important and useful to know the theories behind machine learning,
to know where and how to apply. This also helps one to better interpret the results.
This course on machine learning teaches,
• The theories and concepts behind the techniques.
• The way these techniques need to be applied in R.
• Interpreting and drawing conclusions from the outcomes.
How is this course taught?
We don’t believe in learning theories only. To gain confidence one have to apply the techniques in practical scenario. This course is taught through an unique simulated interface, wherein you will be taught the concepts and theories, the R-commands for the techniques, how they are to be executed in R and the interpretation of the results that R produces. Keep R running in another window, follow the steps as training demonstrates and you will easily get the skills to be able to apply them in your field of work.
