This study introduces a novel human-computer approach for exploring complex biomedical time series data. Our method facilitates the discovery of typical parameter evolutions and clinical scenarios through collaborative interpretation.

Area of Science:

  • Biomedical data analysis
  • Time series analysis
  • Artificial intelligence in healthcare

Background:

  • Exploring biomedical multivariate time series for parameter evolution is challenging due to data complexity.
  • Temporal and multivariate data characteristics, along with context-sensitive interpretation, hinder a priori knowledge formulation.

Purpose of the Study:

  • To propose a novel human-computer collaborative approach for exploring biomedical multivariate time series.
  • To facilitate the construction of typical parameter evolution scenarios through interactive data interpretation.

Main Methods:

  • A human-computer collaborative framework integrating specific annotations.
  • An agent-based design supporting principles of autonomy, adaptability, and emergence.
  • Co-construction of successive abstraction levels for data interpretation.
