UnverifiedThe optimization problem of weighted MMD is non-convex, and when the number of particles is insufficient, gradient flow easily falls into spurious local minima.70% similarUnverifiedFree tiers usually rate-limit; the danger is not the rate limiting itself but silent failure, such as logging a 429 as an error and retrying infinitely in a loop.70% similarUnverifiedOrdinary gradient descent is equivalent to solving the gradient flow ODE using the explicit Euler method, and the Euler method is extremely inefficient when facing stiff equations, requiring very small step sizes to maintain stability.66% similarUnverifiedAt time zero the Markov chain cannot move, so a finite diffusion time must be chosen, which introduces error63% similar
