Efficient AD for the simulation of gradients

6

## Introduction: How would you simulate gradients If you want to simulate the gradient of a random function $Z$, it turns out that you simply need to take derivatives of...

Sum of independent kernels

7

Following this [discourse discussion](https://discourse.julialang.org/t/gps-sum-of-independent-kernels/98542). Currently, there is no building block to sum independent Kernels, analog to `KernelTensorProduct` but with addition instead of multiplication: For inputs $x = (x_1,\dots,x_n)$ and $x'...

To agree with our style guide, we should have underscores separating words (snake_case), and `kernelmatrix` (as well as other functions) should follow this rule

Define `isequal` and `==` more widely between `Kernel`s

16

It would be nice to define `isequal` and/or `==` as widely as possible between `Kernel`s and `Transform`s. At the moment some basic cases seem to be missing, such as ```Julia...

Quick question

Hi All, Thanks for the wonderful package. I'm just starting to explore the source code. I was curious about a very small decision. If I do: ```julia k = SqExponentialKernel()...

Fix docs build

The current docs job is failing due to one of the examples erroring: https://github.com/JuliaGaussianProcesses/KernelFunctions.jl/actions/runs/13119973055/job/36603405080#step:5:46 This looks like a simple update to apply
