Step-by-step community detection in volume-regular graphs

Theoretical Computer Science, 2020
Spectral techniques have proved amongst the most effective approaches to graph clustering. However, in general they require explicit computation of the main eigenvectors of a suitable matrix (usually the Laplacian matrix of the graph). Recent work (e.g., Becchetti et al., SODA 2017) suggests that observing the temporal evolution of the power method ...

Step-Counting Accuracy of a Commercial Smartwatch in Mild-to-Moderate PD Patients and Effect of Spatiotemporal Gait Parameters, Laterality of Symptoms, Pharmacological State, and Clinical Variables

Sensors, 2022
Commercial smartwatches could be useful for step counting and monitoring ambulatory activity. However, in Parkinson’s disease (PD) patients, an altered gait, pharmacological condition, and symptoms lateralization may affect their accuracy and potential ...

HARE: Explainable Hate Speech Detection with Step-by-Step Reasoning

Findings of the Association for Computational Linguistics: EMNLP 2023, 2023
With the proliferation of social media, accurate detection of hate speech has become critical to ensure safety online. To combat nuanced forms of hate speech, it is important to identify and thoroughly explain hate speech to help users understand its harmful effects. Recent benchmarks have attempted to tackle this issue by training generative models on

Step-by-step instructions for detecting whirlpool sign in adnexal torsion

Journal of Rural Medicine, 2023
Objective: Adnexal torsion is a common gynecological emergency whose prompt diagnosis is essential because a delay may lead to ovarian dysfunction. Although the whirlpool sign is reliable for diagnosing ovarian cyst torsion, technical difficulties hinder its use by sonographers.

Step Sequence and Direction Detection of Four Square Step Test [PDF]

IEEE Robotics and Automation Letters, 2017
Poor balance control and falls are big issues for older adults that due to aging decline have a lower postural balance and directional control in balance performance than younger age groups. The four square step test (FSST) was developed to evaluate rapid stepping that is often required when changing direction and avoiding obstacles while walking ...

Pedestrian Dead Reckoning for Multiple Walking Styles Using Classifier-Based Step Detection

IEEE Journal of Indoor and Seamless Positioning and Navigation, 2023
Traditional pedestrian dead reckoning (PDR) systems have been designed for scenarios where users walk straight ahead. However, user behavior observation at the museum revealed that users often stop or walk sideways to look at the exhibits.
