Seismic Waveform Inversion by Stochastic Optimization

Figure 4

Behavior of misfit for various 𝐾. Shown are five different stochastic realizations and the true misfit (dashed line) for (a) 𝐾=1, (b) 𝐾=5, and (c) 𝐾=10. The stochastic misfits approximate the true misfit fairly well for relatively small batch sizes.
