Joint Sampling and Optimisation for Inverse Rendering
SIGGRAPH Asia 2023 Conference Papers, 2023 When dealing with difficult inverse problems such as inverse rendering, using Monte Carlo estimated gradients to optimise parameters can slow down convergence due to variance. Averaging many gradient samples in each iteration reduces this variance trivially. However, for problems that require thousands of optimisation iterations, the computational cost

Joint Inversion of Geophysical Data [PDF]
Geophysical Journal of the Royal Astronomical Society, 2007 Summary. By jointly inverting several different kinds of geophysical measurements at a site we avoid some of the ambiguity inherent in the individual methods. We show how this can be done for the combination of DC resistivity and magnetotelluric measurements on a layered medium by considering a simple 3-layer model.

Structural joint inversion on irregular meshes
Geophysical Journal International, 2019 SUMMARY Structural joint inversion of several data sets on an irregular mesh requires appropriate coupling operators. To date, joint inversion algorithms are primarily designed for the use on regular rectilinear grids and impose structural similarity in the direct neighbourhood of a cell only.
