Seismic Waveform Inversion by Stochastic Optimization

Figure 13

Inversion result for the SA approach with full averaging (𝑛=500) 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. Averaging over the full past dramatically deteriorates the reconstruction.
