 In the context of Gaussian distributions, we recommend either the `Linearization` or `Unscented` method for delta node approximation. The `Linearization` method provides a first-order approximation, while the `Unscented` method delivers a more precise second-order approximation. It's worth noting that while the `Unscented` method is more accurate, it also requires a little more computational resources and has additional hyper-parameters, which may affect the result. By default, delta node approximation in RxInfer.jl employs the `Unscented` method.
