Validating CircaCP: a Generic Sleep-Wake Cycle Detection Algorithm

  title={Validating CircaCP: a Generic Sleep-Wake Cycle Detection Algorithm},
  author={Shanshan Chen and Xinxin Sun},
Sleep-wake cycle detection is a key step when extrapolating sleep patterns from actigraphy data. Numerous supervised detection algorithms have been developed with parameters estimated from and optimized for a particular dataset, yet their generalizability from sensor to sensor or study to study is unknown. In this paper, we propose and validate an unsupervised algorithm – CircaCP – to detect sleep-wake cycles from minute-by-minute actigraphy data. It first uses a robust cosinor model to…

A Generic Algorithm for Sleep-Wake Cycle Detection using Unlabeled Actigraphy Data
A generic, training-free algorithm to detect sleep-wake cycles from minute-by-minute actigraphy, leveraging a robust nonlinear parametric model, circumventing the laborious label collection step in developing customized classifiers for sleep detection.
Sleep/wake state prediction and sleep parameter estimation using unsupervised classification via clustering
A novel approach for integrating unsupervised learning algorithms and domain knowledge heuristics, based on statistical properties of clustered sleep and wake epochs, to develop reliable sleep/wake state prediction models using unlabeled wrist actigraphy data is introduced.
An unbiased, efficient sleep-wake detection algorithm for a population with sleep disorders: Change Point Decoder.
A novel and unbiased data-driven method for detection of sleep-wake and compared its performance to the well-established Oakley algorithm relative to polysomnography in elderly men with disordered sleep achieved balanced performance and higher AUC, despite underestimating sleep/wake transitions.
Actigraphy-based sleep/wake detection for insomniacs
Combining the new and the traditional actigraphic features led to a markedly improved performance in sleep/wake detection compared to that using the traditional feature only, with an increase in Cohen's kappa from 0.49 to 0.55.
Estimating sleep parameters using an accelerometer without sleep diary
The heuristic algorithm uses the variance in estimated z-axis angle and makes basic assumptions about sleep interruptions to detect the SPT-window and shows the value of this algorithm lies in studies such as UK Biobank where a sleep diary was not used.
Wake detection capacity of actigraphy during sleep.
The very low ability of actigraphy to detect wakefulness casts doubt on its validity to measure sleep quality in clinical populations with fragmented sleep or in situations where the sleep-wake cycle is challenged, such as jet lag and shift work.
Sleep and Wakefulness State Detection in Nocturnal Actigraphy Based on Movement Information
The proposed method combines two linear discriminant classifiers, trained with two different criteria involving movement detection to generate a first state estimate, which is refined by a Hidden Markov Model-based algorithm.
Benchmark on a large cohort for sleep-wake classification with machine learning techniques
This work processed the data of the recently published MESA Sleep study to have both PSG and actigraphy data synchronized, and implemented and compared state-of-the-art methods to score sleep-wake stages, which range from the widely used traditional algorithms to recent machine learning approaches.
Automated Method for Detecting Acute Insomnia Using Multi-Night Actigraphy Data
The developed model provides a signature of the condition of acute insomnia obtained from actigraphy only and is very promising as a tool to detect the condition in a non-invasive way and without sleep diaries or any other subjective information.
The National Sleep Research Resource: towards a sleep data commons
The National Sleep Research Resource (NSRR) provides a single point of access to analysis-ready physiological signals from polysomnography obtained from multiple sources, and a wide variety of clinical data to facilitate sleep research.
