Elektrische Me?ger?te und Me?verfahren in the workload of an interpreter. An automatic tracker is described in this chapter, based on artificial neural networks (ANNs), which enables horizons to be tracked in three dimensions with less input from an interpreter compared to most commercial automatic trackers. More time can therefore be s

Each peak represents a single seismic wavelet, and each pre-processed data item corresponds to one neuron in the Hopfield network. The constraint conditions for detecting seismic horizons are us

For example, the conventional method of designing a shaping filter for a minimum-delay wavelet, requires the computation of a fixed filter by the method of least-squares. An alternative approach, considered in this chapter

During training, the global minimum of the energy function is determined using a decimal-encoded genetic algorithm. It is necessary to use weights and thresholds of neurons as a gene group. To determine the weights and thresholds corresponding to the
