UROP

The Mathematics Department has hosted a wide diversity of Undergraduate Research Opportunities Program (UROP) experiences. Every year the Department hosts around 70 different UROP projects.

Here are some recent titles:

  • "Modeling Droplet Dispersion to understand Disease transmission"
  • "Quantum Groups and Hecke Algebras"
  • "Modular Representations of Cherednik Algebras"
  • "Combinatorics of the Bruhat Order"
  • "Eigenvalues and Eigenfunctions of the Laplacian and Schrodinger Operators"

Faculty UROP Coordinators:

More of these projects arose from conversations between the student and the advisor than as a project or idea proposed by the advisor. In almost every case the project represents individual research carried out by the student under the guidance of the advisor.

Mathematical Foundations of Big Data & Machine Learning

Project supervisors: Dr. Jeremy Kepner and Prof. Alan Edelman

Project description

Big Data describes a new era in the digital age where the volume, velocity, and variety of data created across a wide range of fields (e.g., internet search, healthcare, finance, social media, defense, ...) is increasing at a rate well beyond our ability to analyze the data. Machine Learning has emerged as a powerful tool for transforming this data into usable information. Many technologies (e.g., spreadsheets, databases, graphs, linear algebra, deep neural networks, ...) have been developed to address these challenges. The common theme amongst these technologies is the need to store and operate on data as whole collections instead of as individual data elements. This research explore the common mathematical foundation of these data collections (associative arrays) that apply across a wide range of applications and technologies. Associative arrays unify and simplify Big Data and Machine Learning. Understanding these mathematical foundations allows the user to see past the differences that lie on the surface of Big Data and Machine Learning applications and technologies and leverage their core mathematical similarities to solve the hardest Big Data and Machine Learning challenges. This projects seeks to strengthen the mathematical foundations of Big Data and Machine Learning. Participants will be paid.

Combinatorial Algebra and Pure O-Sequences.

Project supervisor: Prof. Fabrizio Zanello

Term: Fall 2017

Project description:

Combinatorics is the art of counting, hence the goal of combinatorial algebra is to count algebraic objects, or sometimes, to use algebraic methods to count combinatorial objects.

One of my recent interests in this area is called "pure O-sequences," a topic that finds (often surprising) applications to a number of different mathematical disciplines. Pure O-sequences can simply be defined as the integer vectors of the form h = (1, h_1, ..., h_N = T), where h_d counts the (monic) monomials of degree d dividing (any one of) T given monomials of degree N. There are several interesting open problems that can also be approached at the undergraduate level, and a good research project on this topic will likely be publishable in a fine international journal. A couple of useful reference are this AMS memoir I cowrote in 2012: https://arxiv.org/abs/1003.3825 , and this survey article: https://arxiv.org/abs/1204.5247 .

This is just one of a number of possible topics. Often, a pure math research project naturally arises from one-to-one discussions between the student and the potential advisor, and it also reflects the tastes of the student in a given area. Therefore, a priori, no combinatorial or ring-theoretic topic is off-limits for this project, and I encourage any interested student to get in touch with me for an informal discussion.

Qualifications:

At least one course in algebra (familiarity with some ring theory is necessary), and possibly one in combinatorics; lots of creativity and eagerness to learn new mathematics.

Learning From Data

Project supervisor: Prof. Gil Strang

Term: Fall 2017

Project description:

The goal is to understand the better success of neural nets for deep learning. With small experiments in machine learning (deep learning), we will start with the open software on playground.tensorflow.org. We need more data on the accuracy as the number of layers and neurons per layer are changed.

Perfect sampling in 2d statistical mechanics

Project supervisor: Prof. Vadim Gorin, Prof. Leonid Petrov

Term: Fall 2017, IAP, and Spring 2018

Project description:

In the recent years integrable random systems (i.e., systems which can be analyzed by means of exact formulas) have been successful in analyzing complicated real-world phenomena ranging from energy spectra of heavy nuclei to shapes of melted crystals and growing bacteria colonies. However, the applicability of exact formulas is (and will remain) limited to special systems, and in order to understand more general models one could try to simulate and visualize them.The goal of this project is to implement existing and develop new methods for perfect sampling (simulations) of large random systems such as the six-vertex (square ice) model and random lozenge tilings. Examples of such systems can be seen in galleries at http://lpetrov.cc/research/gallery/

The student will work with the faculty advisors to learn about integrable random systems and their simulation, and will develop publicly available software for visualization of large random systems. Participants will be paid.

Qualifications:

The student should have taken at least one course in probability, and should be familiar with Markov chains and processes. Coding ability in a language good for fast simulations (such as C/C++ or modern alternatives) is mandatory.

Applied category theory

Project supervisors: Dr. David Spivak

Project description

Category theory is an abstract language for composition---building new things from a collection of already-given things. It is used throughout mathematics and computer science, as well as in other areas of academia, building bridges between these domains. For example, one can use category theory to model information, communication, and interaction between agents.

Undergraduate research projects in applied category theory vary based on the mathematical (and categorical) background of the individual student. Some projects are more applied, others are more abstract. However, all of the projects are real research in the sense that the supervisor (me) doesn't have the 'answer', or even the 'right question' at the outset.

Combinatorial aspects of algebraic geometry and graph theory

Project supervisor: Dr. Dhruv Ranganathan

Project description:

There are a range of possibilities, but I’ve outlined one below.

Title: Graph associahedra and connections to algebraic geometry

Description: Graph associahedra are a large and interesting family of polytopes with a number of remarkable properties. These polytopes are associated to connected finite graphs and are constructed from a simplex by a truncation procedure. In addition to having interesting combinatorics, they arise naturally in fields that include Floer homology, moduli spaces, and knot invariants. In particular, the machinery of toric varieties provide an interesting mechanism to link finite graphs to certain algebraic varieties dubbed “toric graph associahedra". This goal of this project will be to learn, develop, and exploit a dictionary between these two objects. For instance, can one give an algorithm to compute the Betti numbers of a toric graph associahedron in a natural manner from the graph itself? Do natural numerical invariants of the graph encode particular geometric properties of the toric graph associahedron?

Qualifications:

Abstract algebra and basic analysis are the bare minimum requirements, as the rest can be learned "on the go". Courses in topology, algebraic topology, differential geometry, and algebraic geometry will all be useful and relevant, as will some basic knowledge of python/SAGE. A willingness to compute lots of examples will be paramount.

Revisiting the network scale-up method

Project supervisor: Philippe Rigollet

Project description

The network scale-up method has been successfully employed by sociologists to estimate hidden or hard to reach populations (drug injectors, sex workers,...). This method consists in sampling a population by asking the question "How many people do you know in population X?" rather than "do you belong to population X?". Surprisingly, this problem has connection to the matrix completion problem that arises in recommender systems (e.g. the Netflix problem). The goal of this project is to understand and simulate new methods for this kind of data in light of this connection. Other statistical applications, beyond estimation of hidden populations are foreseeable.

Qualifications:

The student should have taken a course on introductory probability and statistics and linear algebra. Interest in graph theory is a plus (for secondary goals) but is not required. Experience with coding is desirable, preferably with Matlab or R.
