Multiview representation learningRaman AroraJohns Hopskins UniversityApplied Math Seminar
View Abstract
Unsupervised learning of useful features, or representations, is one of the most basic challenges of machine learning. Unsupervised representation learning techniques capitalize on unlabeled data which is often cheap and abundant and sometimes virtually unlimited. The goal of these ubiquitous techniques is to learn a representation that reveals intrinsic lowdimensional structure in data, disentangles underlying factors of variation, and is useful across multiple tasks and domains. This talk will focus on multiview representation learning that uses multiple "views" of data to learn improved representations for each of the views. The views can be multiple measurement modalities (audio + video, text + images, tweets + friends network, transaction logs + credit history) but also different information extracted from the same source (words + context, document text + links). The different views often contain complementary information, and multiview representation learning methods can take advantage of this information to learn features that are useful for understanding the structure of the data and that are beneficial for downstream tasks. Multiple views can help by reducing noise (what is noise in one view is not in the other) or improving confidence (when one view is more confident than the other). In this talk, we will focus on novel methodology for multiview learning of representations (features) and applications to speech and language processing, social media analytics and computational healthcare.

Two Tales of FreenessProf. Michael DiPasqualeOklahoma State UniversityTime: 03:45 PMColloquium Series
View Abstract
A graded module over a polynomial ring is free if it has a set of generators so that every module element can be written uniquely as a polynomial combination of the given generators. This is the algebraic analog of a vector bundle over projective space splitting completely. I will discuss two contexts in which freeness plays a crucial role. The first, from approximation theory, is the module of piecewise polynomial functions (splines) over a fixed subdivision. The second, from the theory of hyperplane arrangements, is the module of derivations. Classical work on freeness in these contexts contains a beautiful interplay between combinatorial and geometric features, which we will spend most of the talk exploring. Towards the end we will discuss recent work on connections between splines and hyperplane arrangements.
