Abstract:  Abstract: Multidimensional scaling (MDS) is used to visualize pairwise similarity between objects. Given a distance matrix between objects, we will see how MDS can be used to generate points in some vector space which respect these distances. We will also talk about how this can be extended to a non-linear dimensionality reduction technique known as the Isomap.
