This study introduces a Gaussian process functional regression model for batch data analysis. The novel approach effectively models complex relationships for accurate curve fitting and prediction using covariates.

Area of Science:

  • Statistics
  • Machine Learning

Background:

  • Analyzing batch data requires sophisticated statistical models.
  • Existing methods may not fully capture complex functional relationships.

Purpose of the Study:

  • To propose a novel Gaussian process functional regression model for batch data analysis.
  • To simultaneously model covariance and mean structures, incorporating covariates.

Main Methods:

  • Developed a functional regression model for the mean structure.
  • Employed a Gaussian process regression model for the covariance structure.
  • Integrated covariates into both mean and covariance structures.

Main Results:

  • The proposed model effectively captures nonlinear relationships between functional outputs and covariates.

  • Simulation studies and applications demonstrate strong performance in curve fitting.
  • The method shows excellent predictive capabilities for batch data.

    • Conclusions:

    • The Gaussian process functional regression model offers a powerful tool for batch data analysis.
    • The simultaneous modeling of mean and covariance structures enhances predictive accuracy.
    • The inclusion of covariates provides flexibility and improves model interpretability.
