Seismic Waveform Inversion by Stochastic Optimization

Error between the inverted and true model for the SAA approach with various batch sizes and the full problem, (a) without noise, (b) with noise (SNR = 20 dB), and (c) with noise (SNR = 10 dB). On noiseless data, we achieve a qualitatively comparable result with , as can be seen from (a). For noisy data, however, the largest batch size is not enough to prevent overfitting.
