# Intro to dimensionality reduction

Tags: : Statistics, Machine Learning

Gave a guest lecture on dimensionality reduction at Amir Geva’s “Clustering and Unsupervised Computer Learning” graduate course.
I tried to give a quick overview of major dimensionality reduction algorithms.
In particular, I like to present algorithms via the problem they are **aimed** to solve, and not via **how** they solve it.
