Dimensionality Reduction

Dimensionality reduction is the process of transforming high-dimensional data into a reduced dimension space that best characterizes the full space. In this talk, Misty will discuss two highlights in the history of dimensionality reduction that present two radically different approaches to the problem. The first is the use of matrix factorization, specifically Singular Value Decomposition. The second is the use of a specific type of neural network structure called an autoencoder. The talk will explore both the mechanisms behind the approaches and their uses in different aspects of machine learning.

Presenter: Misty Nodine

    Will the presentation be publicly posted? I have a last minute conflict with work and cannot attend tonight's talk.

      We don't have the infrastructure in place to record presentations right now, but I'll ask Misty if she will post her slides online.

    Will there be any presentations accessible after the meetup?

    May 5, 2014

    • Megan G.

      Yes, like last time, if anyone wants to do a short presentation on something they've been working on, the floor will be open afterwards for that.
