Job Summary

The Professional Research Experience Program (PREP) encourages applications for a Professional Research Assistant! This position will apply machine learning methods to classical statistics procedures.

NIST statisticians recently devised an innovative regression slope estimator based on an artificial neural network (ANN). This ANN estimator outperforms the standard least-squares (LS) estimator in the difficult limited-data/high-noise regime, yielding in this regime 20% or more reduction in standard error with nearly zero bias. Equivalently, for a given target standard error, this ANN estimator performs as well as the LS estimator, but with as much as 30% fewer measurements.

This project will extend this ANN-based method of estimation into different domains to better understand its potential. These domains will include joint estimation of intercept and slope in linear regression and in logistic regression and will consider both uniformly and non-uniformly spaced regression design points. Different ANN architectures will be explored to test the sensitivity of ANN estimation to architecture choice. And architectures will be sought for which the ANN slope estimator’s bias is identically zero by construction.

This project’s results will be presented orally and in written report(s).

The University of Colorado Boulder is committed to building a culturally diverse community of faculty, staff, and students dedicated to contributing to an inclusive campus environment. We are an Equal Opportunity employer, including veterans and individuals with disabilities.
