How do you make a time series sing like a choir? Using the Hilbert-Huang transform to extract embedded frequencies from economic or financial time series [PDF]
The Hilbert-Huang transform (HHT) was developed late last century but has still to be introduced to the vast majority of economists. The HHT transform is a way of extracting the frequency mode features of cycles embedded in any time series using an ...

Signal Processing Methods Monitor Cranial Pressure [PDF]
, 2010 Dr. Norden Huang, of Goddard Space Flight Center, invented a set of algorithms (called the Hilbert-Huang Transform, or HHT) for analyzing nonlinear and nonstationary signals that developed into a user-friendly signal processing technology for analyzing ...

Distribution shifts in trustworthy machine learning
AI Magazine, Volume 47, Issue 1, Spring 2026.Abstract This article investigates the impact of distribution shifts in trustworthy machine learning. To this end, we start by summarizing fine‐grained types of distribution shifts commonly studied in machine learning communities. To tackle distribution shifts across domains, we present our research across various learning scenarios by enforcing ...

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.This work presents a deep learning model to autonomously recognize and classify the secretion retention into three levels for patients receiving invasive mechanical ventilation, achieving 89.08% accuracy. This model can be implemented to ventilators by edge computing, whose feasibility is approved.

Comparative analysis of series fault arc detection methods
Gong-kuang zidonghua, 2017 For uncertainty of line fault location, current series fault arc detection methods are mainly based on current signal analysis. By comparing current waveforms before and after series arc fault under different loads, characteristics and regularities of ...

cScience, Volume 2, Issue 1, March 2026.ABSTRACT The use of informatics for materials design has long promised revolutionary advances through data‐driven discovery; but the untrustworthiness of the available data continues to undermine progress. Indeed, materials knowledge remains fragmented across disciplines and organizations; collaboration faces structural barriers, and the gap between ...

The slow-flow method of identification in nonlinear structural dynamics [PDF]
, 2007 The Hilbert-Huang transform (HHT) has been shown to be effective for characterizing a wide range of nonstationary signals in terms of elemental components through what has been called the empirical mode decomposition.
