Can we add unimodal covariance to PPEs
Something like:
ppe.mean
ppe.covariance
all sorts of issues for multimodal, non-Gaussian cases, etc. The value "Covariance" is still perfectly valid, but then we would also need a way to support PPEs that give multimodal estimates (what are mean and covariances of top 3 distinct modes).
- This starts up all the GMM discussions, EM, Dirichlet Process, buffett/restaurant concentration parameter, etc.
- PS, that's what we'd like to build out more of here: https://github.com/JuliaRobotics/KernelExpectationMaximization.jl
