gpyconform 0.1.0

Extends GPyTorch with Gaussian Process Regression Conformal Prediction

GPyConform

GPyConform extends the GPyTorch library to implement Gaussian Process Regression Conformal Prediction based on the approach described in [1]. Designed to work seamlessly with Exact Gaussian Process (GP) models, GPyConform enhances GPyTorch by introducing the capability to generate and evaluate both 'symmetric' and 'asymmetric' Conformal Prediction Intervals.

Key Features

• Provides Provably Valid Prediction Intervals: Provides Prediction Intervals with guaranteed coverage under minimal assumptions (data exchangeability).
• Inherits All GPyTorch Functionality: Utilizes the robust and efficient GP modeling capabilities of GPyTorch.
• Supports Both Symmetric and Asymmetric Prediction Intervals: Implements both Full Conformal Prediction approaches for constructing Prediction Intervals.

Note

Currently, GPyConform is tailored specifically for Exact GP models combined with any covariance function that employs an exact prediction strategy.
