The Potential of Ensemble‐Based Automated Sleep Staging on Single‐Channel EEG Signal From a Wearable Device

Journal of Sleep Research, EarlyView.
ABSTRACT Machine‐learning‐based sleep staging models have achieved expert‐level performance on standard polysomnographic (PSG) data. However, their application to EEG recorded by wearable devices remains limited by non‐conventional referencing montage and the lack of benchmarking against PSG.

Characteristic kernels on Hilbert spaces, Banach spaces, and on sets of measures

We present new classes of positive definite kernels on non-standard spaces that are integrally strictly positive definite or characteristic. In particular, we discuss radial kernels on separable Hilbert spaces, and introduce broad classes of kernels on ...

Strong and Weak Episodic Memories Are Shaped by Multiple Cycles of NREM Spindles and REM Alpha Bursts

Journal of Sleep Research, EarlyView.
ABSTRACT Prior research has built up the notion that non‐rapid eye movement sleep (NREM) and rapid eye movement sleep (REM) are separately important for specific types of memory. However, growing evidence suggests that these sleep stages work in conjunction to jointly shape memory.

partial translation algebras for certain discrete metric spaces

, 2010
The notion of a partial translation algebra was introduced by Brodzki, Nibloand Wright in [11] to provide an analogue of the reduced group C*-algebrafor metric spaces.

Adaptive Estimation for Weakly Dependent Functional Times Series

Journal of Time Series Analysis, EarlyView.
ABSTRACT We propose adaptive mean and autocovariance function estimators for stationary functional time series under 𝕃p−m‐approximability assumptions. These estimators are designed to adapt to the regularity of the curves and to accommodate both sparse and dense data designs.
