This study introduces a novel geometrical prior distribution for inferring probability distributions from data. This method enhances solution specificity and uses numerical sampling for better visualization and probabilistic inference.

Area of Science:

  • Statistics
  • Probability Theory
  • Machine Learning

Background:

  • Inferring continuous probability distributions from finite data is a key challenge.
  • Prior approaches often rely on scalar field theory for prior distributions.

Purpose of the Study:

  • To present a more general, geometrically interpretable prior distribution for probability inference.
  • To demonstrate the utility of numerical sampling for posterior distribution analysis.

Main Methods:

  • Developed a novel prior probability distribution with a geometrical interpretation.
  • Employed numerical sampling of the posterior probability distribution.
  • Utilized histograms for visualization and probabilistic inference.

Main Results:
