... is also treated as a variable, which we hope to estimate. We use Voronoi cells and represent our 2D velocity model using certain nuclei points and employ a recently developed method called the Reversible Jump Hamiltonian Monte Carlo (RJHMC). RJHMC is an effective tool for model exploration and uncertainty...

... to the birth-death approach. Model updates are computed using gradient information and the Metropolis-Hastings criterion is used for model acceptance. We have applied this technique to pre-stack (angle stack) AVA inversion for estimating acoustic and shear impedance profiles. Our results demonstrate that RJHMC...
