This study introduces a novel algorithm for diagnosing Parkinson's disease (PD) using speech data. By simultaneously selecting speech samples and features, it significantly improves classification accuracy for PD detection.

Area of Science:

  • Biomedical Engineering
  • Computational Linguistics
  • Neurology

Context:

  • Parkinson's disease (PD) diagnosis using speech data is an emerging field.
  • Existing methods focus on feature extraction and classifier design, neglecting instance selection.
  • Previous work indicated instance selection enhances classification accuracy.

Purpose:

  • To propose a novel algorithm for Parkinson's disease diagnosis by simultaneously selecting speech samples and features.
  • To leverage the synergy between speech samples and features for improved diagnostic performance.
  • To address the gap in understanding the relationship between speech samples and their relevant features.

Summary:

  • A new algorithm for PD diagnosis integrates relevant feature weighting and multiple kernel learning.
Keywords:
