Our method builds and improves upon the state-of-the-art Gaussian process (GP) change point model benchmark of Saatçi et al. (2010). The Student-t process generalizes the concept of a GP and hence yields a more flexible alternative. Additionally, unlike a GP, the predictive variance explicitly depends on the training observations, while the use of an entangled Student-t noise model preserves analytical tractability. Our approach also uses a Hilbert space reduced-rank representation of the TP kernel, derived from an eigenfunction expansion of the Laplace operator (Solin & Särkkä, 2020), to alleviate its computational complexity. Improvements in prediction and training time are demonstrated with real-world data sets."^^<http://www.w3.org/2001/XMLSchema#string> . <https://discovery.ucl.ac.uk/id/eprint/10180942>
