Hi Zeyi 

For the data reduction question it asks use to perform numerosity "reduction using 
sampling and feature reduction." 

Does this mean we need to perform sampling and feature reduction on one version of the 
original data, and compare this to the original data.

Or do we perform sampling reduction on original data, and compare it with feature 
reduced original data?

thanks

The first one. You should perform sampling+feature reduction on the data set.
