Education

edit

Rosenfeld received his B.Sc. in mathematics and physics from Tel Aviv University in 1985. He received his Ph.D. in computer science from Carnegie Mellon University in 1994. While a graduate student, he developed and open-sourced a statistical language-modeling toolkit to allow anyone to create statistical language models from their own corpora and experiment with and extend the toolkit's capabilities.[3] The toolkit has been used by more than 100 NLP laboratories in more than 20 countries.[4]

Rosenfeld's Ph.D. thesis, A Maximum Entropy Approach to Adaptive Statistical Language Modeling,[5] was advised by Raj Reddy and Xuedong Huang and won the 2001 Computer, Speech and Language award for "Most Influential Paper in the Last 5 Years."[6]

Career

edit

Shortly after receiving his Ph.D., Rosenfeld joined the faculty of the Carnegie Mellon School of Computer Science as an assistant professor. He was promoted to the rank of associate professor in 1999 and received tenure in 2001.[7] In 2005 he was promoted to professor of language technologies, machine learning computer science and computational biology in the School of Computer Science at Carnegie Mellon University. Rosenfeld also holds adjunct appointments at the University of Pittsburgh School of Medicine, department of computational and systems biology.[8][9]

From 2002 to 2003, Rosenfeld was a visiting professor at the University of Hong Kong.[7]

Rosenfeld is the director of Carnegie Mellon's Machine Learning for Social Good (ML4SG) program.[10] He has held educational leadership positions in a variety of programs, including the M.S. in computational finance (1997–1999), graduate computational and statistical learning (2001–2003), M.S. in machine learning (2017) and undergraduate minor in machine learning.[7]

Rosenfeld was appointed Head of Carnegie Mellon's Machine Learning Department in 2018.[1]

Research

edit

Rosenfeld's research interests include epidemiological forecasting, information and communication technologies for development (ICT4D), and machine learning for social good.[11]

Epidemiological forecasting

edit

Rosenfeld is a world expert in epidemiological forecasting.[12] He founded and directs the Delphi research group, which has won most of the epidemiological forecasting challenges organized by the U.S. CDC and other U.S. government agencies.[13] In December 2016, the CDC named his group the "Most Accurate Forecaster" for 2015–2016,[14] and in October 2017, the Delphi group's two systems took the top two spots in the 2016-2017 flu forecasting challenge.[15] The CDC recognized Rosenfeld's Delphi group at Carnegie Mellon University as having contributed the most accurate national-, regional-, and state-level influenza-like illness forecasts and national-level hospitalization forecasts to the site.[16][17] In 2019, the CDC recognized forecasts provided by the Delphi group at Carnegie Mellon as having been the most accurate for five seasons in a row,[18] and named the Delphi group an Influenza Forecasting Center of Excellence, a five-year designation that includes $3 million in research funding.[19]

Rosenfeld describes his forecasting research goal as "to make epidemiological forecasting as universally accepted and useful as weather forecasting is today."[20] His recent work in the area has focused on selecting high value epidemiological forecasting targets (e.g. Influenza and Dengue); creating baseline forecasting methods for them; establishing metrics for measuring and tracking forecasting accuracy; estimating the limits of forecastability for each target; and identifying new sources of data that could be helpful to the forecasting goal.

Honors and awards

  • 2017 Joel and Ruth Spira Teaching Award[21]
  • 2017 CDC Influenza Forecasting Challenge "Most Accurate Forecaster"[22][23]
  • 1992 Allen Newell Medal for Research Excellence[24]
