Regression Analysis and Classification (PetscRegressor)#

The Regression Analysis and Classification (PetscRegressor) component provides a simple interface for supervised statistical (or machine) learning regression (prediction of continuous numerical values) or classification (prediction of discrete labels or categories) tasks.

PetscRegressor internally employs Tao (or KSP for a few, specialized cases) to solve the underlying numerical optimization problems. PetscRegressor users can set Tao options or otherwise directly manipulate the underlying Tao context, which can be accessed via PetscRegressorGetTao().
