"filter examples having values from an interval"

fritmore

HI there

how (if possible) can I filter only examples taht take on values from an interval?
e.g. att1=[1...9]

in the Filter examples>attribute_value_filter I managed to do only this e.g. att1=5 but not an interval......
???

Hi,

you can use this process:

<宏/ >

<运营商激活d="true" class="process" compatibility="5.1.008" expanded="true" name="Process">

<运营商激活d="true" class="retrieve" compatibility="5.1.008" expanded="true" height="60" name="Retrieve" width="90" x="45" y="30">


<运营商激活d="true" class="generate_attributes" compatibility="5.1.008" expanded="true" height="76" name="Generate Attributes" width="90" x="179" y="30">




<运营商激活d="true" class="filter_examples" compatibility="5.1.008" expanded="true" height="76" name="Filter Examples" width="90" x="313" y="30">



<运营商激活d="true" class="select_attributes" compatibility="5.1.008" expanded="true" height="76" name="Select Attributes" width="90" x="447" y="30">

You just need to specify the range in the Generate Attribute operator, rename the column from "Test" to whatever you need and you're good to go

thank you Marco,

it works, BUT I had to convert nominal label of interest into numerical and after filtering back into nominal. This is really clumsy way to do something like value range
selection. :-\

Hope this will be implemented as part of a single operator e.g. filter examples including nominal list filtering or perl like script selection.
cheers

Hi,

well it's always helpful to have a numerical value if you want to do range filtering
If you don't like the above process, you can do the same thing with the Execute Script operator, you will just need to write your own groovy script.
