Gaussian Process Machine Learning
Gaussian Process Machine Learning. Gaussian processes (gps) provide statistically optimal predictions in the sense of unbiasedness and maximal precision. The red line shows the predicted mean value at.
It draws explicit connections to branches such as spline smoothing models and support vector machines in which similar ideas have been investigated. Treated within a bayesian framework, very powerful statistical methods can be implemented which offer valid estimates of uncertainties in our predictions and generic model. Consider the training set , where and , drawn from an unknown distribution.

•the problem of learning with gaussian processes is exactly the problem of learning the hyperparameters of the covariance function. They can be used to specify distributions over Although the modern implementation of gps as a machine learning technique is more capable and flexible than kriging, their employment in environmental science is less routine.
