Influence of the Bounds of the Hyperparameters on the Reconstruction of
  Hubble Constant with Gaussian Process
  The cosmological model-independent method Gaussian process (GP) has been
widely used in the reconstruction of Hubble constant $H_0$, and the
hyperparameters inside GP influence the reconstructed result derived from GP.
Different hyperparameters inside GP are used in the constraint of $H_0$ derived
from GP with observational Hubble parameter $H(z)$ data (OHD), and the
influence of the hyperparameters inside GP on the reconstruction of $H_0$ with
GP is discussed. The discussion about the hyperparameters inside GP and the
forecasts for future data show that the consideration of the lower and upper
bounds on the GP's hyperparameters are necessary in order to get an
extrapolated result of $H_0$ from GP reliably and robustly.
