WebDec 31, 2024 · To fit a Gaussian Process, you will need to define a kernel. For Gaussian (GBF) kernel you can use GPy.kern.RBF function. Task 1.1: Create RBF kernel with variance 1.5 and length-scale parameter 2 for 1D samples and compute value of the kernel between 6-th and 10-th points (one-based indexing system).
