2013-14: LDHD: LDHD Summer School: August 11-16, 2013

Location

This summer school was held at the Radisson Hotel in Research Triangle Park, NC.

Description

Recent technological advancements allow for the collection of higher dimensional data as well as data with more complicated structure. A fundamental problem is to identify low- dimensional structure in high-dimensional systems (LDHD). The challenges in addressing these problems are theoretical as well as computational and intersect with many application areas. This summer school gave students an overview of the fast growing area of LDHD, as a prelude to the year-long SAMSI program on LDHD.

The school covered existing theoretical and computational tools to analyze LDHD. The short courses were at the graduate level; they were aimed at advanced PhD students, postdocs, and faculty.

The titles, lecturers, and prerequisites for the courses:

  1. Title: Topological and geometrical structures in data analysis
    Lecturer: Vin de Silva
    Prereqs: basic knowledge of analysis is assumed; some knowledge of topology is useful but not required
  2. Title: Bayesian learning from big data
    Lecturer: David Dunson
    Prereqs: basic familiarity with the Bayesian paradigm (course is aimed at advanced graduate students, postdoctoral fellows, and faculty with expertise in statistics); recommended background reading: the initial chapters in “A First Course in Bayesian Statistical Methods”, by Peter Hoff
  3. Title: Population and familial structure in genetic association studies
    Lecturer: Ann Lee
    Prereqs: none specified
  4. Title: Randomness in geometry and topology: finding order in the chaos
    Lecturer: Elizabeth Meckes
    Topics: topology of randomly constructed spaces; low-dimensional projections of high-dimensional distributions; random unitary matrices; probability and high- dimensional convex geometry
    Prereqs: undergrad-level probability theory and matrix analysis
  5. Title: Convex and nonconvex methods for high dimensional sparse estimation
    Lecturer: Tong Zhang
    Prereqs: prior exposure to sparsity and high dimensional statistics
  6. Title: Genomics and high-dimensional optimization
    Lecturer: Hua Zhou
    Prereqs: interest in modern genomics, computation, or both
