Talk description (Track One)

Data is often high-dimensional - millions of pixels, frequencies, categories. A lot of this detail is unnecessary for data analysis - but how much exactly? This talk will discuss the basic principles and techniques of dimensionality reduction, provide (just a little!) mathematical intuition about how it's done, and use scikit-learn to show you how Netflix uses it to lead you from binge to binge.
