#

If we consider the Gaussian process model as a prior on functions, then many sparse GPs can be considered as alternative priors on functions.

#

Sparse GPs: approximate the posterior, not the model

#

This seems to help on some datasets. The beauty of this is that it is totally clear that improving the ELBO will improve the approximation:

#

Ed Snelson’s Publications

The construction is as follows. We can always add more inducing points:

#

Let's look at some concrete examples: Snelson, Edward, and Zoubin Ghahramani.

#

The approximation is nonparametric. A neat thing about this approach was that the locations of these pseudo-inputs could be found by unconstrained gradient-based snelosn of the marginal likelihood.

#

Outlook Variational Bayes gives a solid foundation for research in approximate inference for Gaussian processes.

#

This means that behaviour of the predictions away from the data takes the same form as the true posterior usually increasing ed snelson thesis variance away from the data. Should we modify the model switch to a different kernel or should we modify the approximation increase the dissertation proposal example of inducing points?

#

The model seemed to overfit.

#

Outlook Variational Bayes gives a solid foundation for research in approximate inference for Gaussian processes.

#

The whole process is included in the approximation, so we simply have to evaluate the approximate posterior GP to make a prediction. Further reading Two recent papers have made excellent contributions.

Let's look at some concrete examples:.

The term thezis from some of the original work in this area, where methods used a subset of the dataset to approximate the kernel matrix e.

#

This gives us a solid foundation on which ghesis build approximations to the posterior of many Gaussian process models, including GP classification, GP state-space models, and more.

#

But how are we to know if a dataset needs a heteroscedastic model? The model seemed to overfit.

#

Sparseness occurred through selection of the datapoints.

There is an accumulation of evidence that the FITC method overfits. It is clear what to do at predict time.

Even the most expert deep learning researchers will use a GP for regression problems with small numbers of data points Bengio or in the context of optimising hyper-parameters of deep learning models and algorithms Snoek et al.

A neat thing about this approach was that the locations of these pseudo-inputs could be found by unconstrained gradient-based optimisation of the marginal likelihood. This seems to help on some datasets. Sparseness occurred through selection of the datapoints. Two recent papers have made excellent contributions.

Now we understand that the variational method proposed by Titsias and other related methods, e. Advantages These expressions appear superficially similar to the approximate-prior approach, but the underpinning idea is where most of the value lies. For larger datasets, researchers have spent years trying to make reasonable approximations so that they can use GPs in those settings too: If I want such a model, I want to specify it, understand it and subject it to model comparison and criticism.

Equally, suppose we fit a model using FITC and it performs really well. A question I often get asked is: The FITC approximation conflated with early stopping, which made it hard to know what was wrong. Some immediate advantages include:. There is an accumulation of evidence that the FITC method overfits.
