The PIDC has accumulated millions of seismic phase readings for the current
threecomponent stations, which were not availableat the timeofthe originalneural

Modern 3-D seismic surveys, with their increased quantities of recorded data,
have only exacerbated this bottleneck in the productivity of processing seismic
data. Previous efforts to automate the picking of first-arrival times, rely on various
models of the refraction process (Hatherly, 1982; Gelchinsky and Shtivelman,
1983; Coppens, 1985; Spagnolini, 1991). Recently, neural networks have been
brought to bear on many pattern recognition problems. Quite naturally then, they
have ...

Abstract We train an artificial neural network to perform decon- volution of seismic
data and thereby recognize and remove multiple arrivals in reflection seismic
data. Basis for the learning process is a well log that is typical for the area in
which the data were gathered. Modeling data from this well log and comparing it
to real recorded data allows deduce relations between the subsurface model in
the recorded data. In contrast to conventional geophysical data processing
techniques, ...

6 Feedback Process Neural NetWorks A feedback neural network is an artificial
neural network model that has been widely applied to signal processing ",
optimal computation", convex nonlinear programming", seismic data filtering", etc.
A traditional feedback neural network model generally has time-invariant inputs.
However, when a biological neural organization processes information, it actually
feeds back time-delay information and the inputs of external signals will last for a
period ...

As a result, the conventional nonparametric methods have found wide use in
advanced radar, sonar, communication, speech, biomedical, geophysical, and
other data processing systems. However, two problems plague nonparametric
spectral estimation methods, namely, high estimation variances and low
resolution, particularly, in the cases that the data are short and the signal-to-noise
ratio is low. As an alternative, parametric spectral estimation methods have been
proposed and ...
