In FWI, it's the difference between the forward-modeled wavefield and the recorded data. The optimal result is the set of parameters that result in the minimum difference or 'cost'. One way to find this minimum is gradient descent.</flowPara><flowPara

   id="flowSpan4983">g</flowSpan> to our guess, where α is some small number; if the gradient is positive, as shown, this has the effect of increasing the parameter for the next guess. Iterating, we eventually find the minimum. </flowPara></flowRoot>    <path
