Seismic Waveform Inversion by Stochastic Optimization

Error between the inverted and true model for the SA approach with full averaging for various batch sizes and the full problem, (a) without noise, (b) with noise (SNR = 20 dB), and (c) with noise (SNR = 10 dB). Averaging over the full past slows down the convergence dramatically.
