Data Scrubbing Operation: Dimension Reduction
This lesson will introduce you to the concept of dimension reduction.
We'll cover the following...
Quick overview
Dimension reduction, also known as descending dimension algorithms, transforms data to a lower dimension. This can help to lessen computational resources and visualize patterns in the data.
Dimensions are the number of variables describing the data, such as the city of residence, country of residence, age, and gender. Four variables can be plotted on a scatterplot, but three-dimensional and two-dimensional plots are easiest for the human eye to interpret.
The goal of a descending dimension ...
