Local Change Point Detection and Cleaning of EEMD Signals with Application to Acoustic Shockwaves

no code implementations1 Mar 2021 Kentaro Hoffman, Jonathan M. Lees, Kai Zhang

Using this technique, we demonstrate improved signal cleaning performance for acoustic shockwave signal detection.

Effects of Epileptiform Activity on Discharge Outcome in Critically Ill Patients

no code implementations9 Mar 2022 Harsh Parikh, Kentaro Hoffman, Haoqi Sun, Wendong Ge, Jin Jing, Rajesh Amerineni, Lin Liu, Jimeng Sun, Sahar Zafar, Aaron Struck, Alexander Volfovsky, Cynthia Rudin, M. Brandon Westover

Having a maximum EA burden greater than 75% when untreated had a 22% increased chance of a poor outcome (severe disability or death), and mild but long-lasting EA increased the risk of a poor outcome by 14%.

Do We Really Even Need Data?

no code implementations14 Jan 2024 Kentaro Hoffman, Stephen Salerno, Awan Afiaz, Jeffrey T. Leek, Tyler H. McCormick

As artificial intelligence and machine learning tools become more accessible, and scientists face new obstacles to data collection (e. g. rising costs, declining survey response rates), researchers increasingly use predictions from pre-trained algorithms as outcome variables.

From Narratives to Numbers: Valid Inference Using Language Model Predictions from Verbal Autopsy Narratives

no code implementations3 Apr 2024 Shuxian Fan, Adam Visokay, Kentaro Hoffman, Stephen Salerno, Li Liu, Jeffrey T. Leek, Tyler H. McCormick

In this paper, we develop a method for valid inference using outcomes (in our case COD) predicted from free-form text using state-of-the-art NLP techniques.
