< 数据挖掘--实用机器学习技术及java实现> 一书结合数据挖掘和机器学习的知识,作者陈述了自动挖掘模式的基础理论,并且以java语言实现了具有代表性的各类数据挖掘方法.例如:class

<PRE>
public void <B>preProcess</B>()
                throws java.lang.Exception</PRE>

<DD>Perform any postprocessing. When this method is called, it indicates

 will be sent. The ResultProducer should call

<DL>
<DD>Gets the results for a specified run number. Different run
 numbers correspond to different randomizations of the data. Results
 produced should be sent to the current ResultListener, but only
 if the ResultListener says the result is required (it may already
 have that result). A single run may produce multiple results.<DD><DL>

 The names should not contain spaces (use '_' instead for easy 
 translation.)<DD><DL>

<A NAME="getCompatibilityState()"><!-- --></A><H3>
getCompatibilityState</H3>
<PRE>
public java.lang.String <B>getCompatibilityState</B>()</PRE>
<DL>
<DD>Gets a description of the internal settings of the result
 producer, sufficient for distinguishing a ResultProducer
 instance from another with different settings (ignoring
 those settings set through this interface). For example,
 a cross-validation ResultProducer may have a setting for the
 number of folds. For a given state, the results produced should
 be compatible. Typically if a ResultProducer is an OptionHandler,
 this string will represent those command line arguments required
 to set the ResultProducer to that state.<DD><DL>
