By Gijs J. O. Vermeer

A vital factor for profitable 3-D seismic survey layout is a simple figuring out of the spatial houses of the seismic wavefield. those homes have been defined for 2-D seismic info in Seismic Wavefield Sampling by way of an identical writer. This ebook extends the outline into the even more complicated box of three-D seismic facts. A bankruptcy on directions for survey layout interprets thought into perform. a few case histories illustrate the innovations. Noise suppression, answer, and imaging are mentioned intimately. Converted-wave survey layout is roofed in a separate bankruptcy. This publication presents crucial wisdom for any acquisition or processing geophysicist and is suggested to all people facing 3-D seismic information. An incorporated CD-ROM additionally comprises an Acquisition layout Wizard and survey optimization software program.

Zur Verzweigung wird das "statistischsignifikanteste" Merkmal benutzt. Er zahlt zu den direkten TopDown-Verfahren ohne die Verwendung einer nachfolgenden Pruning-Phase. Aufgrund Ihrer leichten Anwendbarkeit und Interpretierbarkeit haben Entscheidungsbaumverfahren auch in gangigen Statistikpaketen, Entscheidungsunterstutzungssystemen oder Data Mining Toolkits Einzug gefunden. Beispielsweise sind Implementierungen und entsprechende Modifikationen von CHAID auch in den bekannten Statistikpaketen SPSS und SAS verfugbar.
