Modules … WebApr 14, 2024 · For the linear example, note that the GPy model ended up with a fairly low variance (~0.07) whereas in your GPflow example the variance ended up being much higher (~1.7). What happens if you initialise the linear kernel in GPflow with a lower variance (try gpflow.kernels.Linear(variance=0.1) )? WebThose who have used the GPy or GPflow Python packages will find the syntax for construction mean and covariance functions somewhat familiar. When first instantiated, the mean and covariance functions are parameterized, but not given their inputs yet. ... Using gp.Latent for the example, the syntax to first specify the GP is: gp = pm. gp.
