How to identify which variables are important in a large dataset?




I am currently trying to explore the dataset on Human Activity Recognition on Smartphones, and the training dataset contains 561 variables.
How to identify the important variables from among such a large number of variables?



Hi Aditya,

One of the ways to find is to apply the algorithm upon the dataset and see the summary of the model which list outs the important variables.
