user based discretization

satyendra

hiii all,
          i facing problem in userbased discretization. i am working on medical dataset.in that data set i want to divide an attribute 'pregnant' in three parts in the folloing manner

low(0,1)
medium(2,4,5,6)
high(6<)

now my problem is how to do it.please help me in this......
                                                  with regards,
                                                        satyendra ???

Hi Satyendra,
if you are really going to get to know which of your patients are medium pregnant, here's the way to go:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.0">
  <context>
    <input>
      <location/>
    </input>
    <output>
      <location/>
      <location/>
    </output>
    <macros/>
  </context>
  <operator activated="true" class="process" expanded="true" name="Process">
    <process expanded="true" height="-20" width="-50">
      <operator activated="true" class="generate_data" expanded="true" height="60" name="Generate Data" width="90" x="131" y="90"/>
      <operator activated="true" class="rename" expanded="true" height="76" name="Rename" width="90" x="327" y="98">
        <parameter key="old_name" value="att1"/>
        <parameter key="new_name" value="pregnant"/>
      </operator>
      <operator activated="true" class="discretize_by_user_specification" expanded="true" height="94" name="Discretize" width="90" x="530" y="95">
        <parameter key="attribute_filter_type" value="single"/>
        <parameter key="attribute" value="pregnant"/>
        <list key="classes">
          <parameter key="flow" value="1.0"/>
          <parameter key="medium" value="6.0"/>
          <parameter key="high" value="Infinity"/>
        </list>
      </operator>
      <connect from_op="Generate Data" from_port="output" to_op="Rename" to_port="example set input"/>
      <connect from_op="Rename" from_port="example set output" to_op="Discretize" to_port="example set input"/>
      <connect from_op="Discretize" from_port="example set output" to_port="result 1"/>
      <portSpacing port="source_input 1" spacing="0"/>
      <portSpacing port="sink_result 1" spacing="0"/>
      <portSpacing port="sink_result 2" spacing="0"/>
    </process>
  </operator>
</process>

Anyway an interesting philosophical question: Can one be a little bit pregnant?
