In previous work, we introduced Gaussian processes for
machine learning as a novel nonlinear tool for designing
digital communication receivers. Gaussian processes can
be applied to regression ... we use both settings for tuning digital
communication receivers with short training sequences.
We compare Gaussian processes for regression (GPR) and
