Updated January, 2020


James Madison University (JMU) has been chosen for a National Science Foundation Research Experiences for Undergraduates (REU) site in mathematics. All interested undergraduates (who are US citizens or permanent residents) are encouraged to apply for this eight week program, in which students will work in groups of 2-4 under the supervision of their faculty mentors.

Housing and a $4,500 stipend are supplied, as well as full use of university facilities and travel expenses.


May 25 2020 - July 17 2020.


Bias Mitigation for Machine Learning Estimators: As machine learning estimators are gaining more and more attentions, so is the study of the accuracy of these estimators. In this project, we will assess the accuracy of some most popular machine learning estimators, including random forest and boosting estimators. In many situations, the dominant component in the risk turns out to be the squared bias, which leads to the necessity of bias correction. We will focus on comparing the degree of biasedness of these estimators and exploring the effectiveness of adaptive bagging and bias correction bootstrap techniques in reducing bias.

The students will get familiar with the popular machine learning estimators and learn how to assess statistical risks. The students will also gain experiences with R programming.

Mentors: Lihua Chen and Prabhashi Gamage

Please visit mathprograms.org to apply. Application deadline is February 21, 2020.

Common reply date

This REU participates in the Mathematical Sciences REU Common Reply Date agreement. Any student who receives an offer from an REU that participates in the Common Reply Date agreement, including this REU, is not required to accept or decline the offer until March 8, 2020 (or later). The goal of the Common Reply Date agreement is to help students make informed decisions, particularly when faced with the potential of receiving offers from multiple REUs.

More Information

JMU is located in the beautiful Shenandoah Valley, bordered on the east by the Blue Ridge Mountains and on the west by the Allegheny Mountains. With sections of the George Washington National forest in both mountain ranges, there are excellent opportunities for hiking and camping in the area. Mountain biking is also very popular, and the rolling countryside makes for excellent road riding as well. There are a number of historical sites in the area, including the New Market Battlefield, for history buffs. Washington, D.C., with all its cultural opportunities, is only a 2-hour drive to the northeast. On-campus housing will be provided for mathematics and statistics REU students in the same building as the research students from other programs, and there will be a number of common social activities among these groups during the program.
