Lu–Lu–Nolen scaling conjecture for concentrated-kernel SVGD
Lu–Lu–Nolen scaling conjecture. If the kernel is scaled proportionally to the number of particles as $N^\beta K(N^\beta\,\cdot)$ , then the behavior of the particle system should re…

Improved convergence rates for GB-SVGD in the small-data regime
Conjecture on GB-SVGD rates. The convergence rates of GB-SVGD can be improved even in the regime $n \ll KT$ . The paper establishes provably fast convergence guarantees for finite-p…
