that samples the posterior so in a sense by running the gradient flow we are aiming to solve the wrong problem so no wonder that we do a bit worse so that's not surprising but you know it's it's a non-trivial curve in this diagram so can we explain it can we kind of understand intuitively where it comes from so kind of the popular explanation of why for some parameters the gradient flow would be working and why for others it will not be working will be kind of this this cartoon with spurious local minima that either are
