Types of Errors: Detection and Minimization

Error is the deviation of the obtained result from the true, expected value or the estimated central value. Errors are expressed in absolute or relative terms.
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
Systematic or...

This study introduces a support vector machine (SVM) method for detecting falls during daily activities. This advanced fall-detection system achieved high accuracy, outperforming traditional threshold methods.

Area of Science:

  • Biomedical Engineering
  • Gerontology
  • Machine Learning

Background:

  • Fall detection systems are crucial for monitoring and assisting individuals, especially the elderly.
  • Traditional threshold-based algorithms using accelerometers have limitations in detecting complex falling activities.
  • Activities of daily life (ADLs) involving rapid center of gravity decline are defined as falls.

Purpose of the Study:

  • To develop and evaluate a novel fall-detection system using a support vector machine (SVM) for improved accuracy.
  • To differentiate falling ADLs from non-falling ADLs based on center of gravity dynamics.
  • To replace traditional threshold methods with a more robust SVM-based approach for fall detection.

Main Methods:

  • Utilized a support vector machine (SVM) with a hyperplane as the separating boundary for fall detection.

Design and Analysis for Fall Detection System Simplification

Published on: April 6, 2020

  • Collected data from young (20 subjects) and elderly (5 subjects) volunteers performing scripted and unscripted ADLs.
  • Focused on parameters related to the body's center of gravity during various activities.

    • Main Results:

    • The SVM model achieved high accuracy, reaching 99.1% in training and 98.4% in testing using four input vector parameters.
    • During a one-hour continuous unscripted test, the system demonstrated low false positive rates: two for young volunteers and one for elderly volunteers.
    • The SVM approach proved effective in distinguishing falling ADLs from non-falling ADLs.

    Conclusions:

    • The SVM-based fall-detection system offers a significant improvement over traditional threshold methods.
    • This method shows high accuracy and reliability for detecting falls during activities of daily life in both young and elderly populations.
    • The proposed system has strong potential for real-world application in fall prevention and monitoring.
