WebThe lengthscale ℓ determines the lengthscale function in the same way as in the SE kernel. Locally Periodic Kernel A SE kernel times a periodic results in functions which are periodic, but which can slowly vary over time. kLocalPer(x, x ′) = kPer(x, x ′)kSE(x, x ′) = σ2exp(− 2sin2 ( π x − x / p) ℓ2)exp(− ( x − x)2 2ℓ2) Web11. You want to sample posterior using the data and model given. In this case you can: sample from posterior normal distribution with given mean and covariance matrix - use model.predict with full_covariance=True in case; use built-in function model.posterior_samples_f that does the job for you. A sample code is below:
