Seismic Waveform Inversion by Stochastic Optimization

Figure 9

Inversion result for the SA approach without averaging for various batch sizes and noise levels. The rows represent different batch sizes 𝐾=1,5,10, while the columns represent different noise levels: no noise, SNR = 20 dB, and SNR = 10 dB. We obtain good results with 𝐾=1, and the quality does not improve dramatically for larger batch sizes, except for the highest noise level.
