R Programming Languaage Integration
The R Programming Language and integrating it with Microsoft Azure Machine Learning#
What is R?#
R is an open source statistical programming language
CRAN The comprehensive R Archive Network is the repo for tools and libraries
Using with Azure Machine Learning Studio#
There is a module called Execute R Script
You can write R code directly in the module
The module allows 2 input datasets, an R Script and an optional zipped set of R scripts
Principal Component Analysis (PCA)#
A Dimensionality reduction technique: it finds a new set of variables, principal components, that are linear combinations of the original dataset and are uncorrelated with all other variables
Note on Trained Models: You can only visualise the results of R algorithms, you cannot use results as input to other machine learning or save as trained models
Time Series#
You can use R Auto-ARIMA or R K-Nearest Neighbor for time series data
