The problem is the result of clustering

jabra

Hello
Dear engineers
I want to cluster
I have five columns
I want to cluster in the third column, which is the text
With the select attribute operator I chose the third column for clustering.
I want to put the clustering result at the end of the clustering, in the output of all the columns, plus the column.
what should I do???
Thank you so much if you help me

Hi @jabra,

 

Can you share your dataset and your process, please ?

Otherwise, can you give an example of what you want to obtain : I have difficulties to understand what you want to do.

 

Regards,

Hello
thanks for your response
I have no access to the data and my rapidminer file. Which I send.
But
look
I have five columns with the names: idiot. name . lable. Address. Description . I have
I want to cluster the description based on the column name.
But
At the end of the clustering on the output. I have all the columns with the cluster output column. that's mean
  Idiot name . lable. Address. Description and cluster
In the output, I can tell which sentence in the cluster has the x lable.
Thank you very much if you help me

Hi @jabra

 

I propose you this process (to adapt and complete with your own data) : 

<?xml version="1.0" encoding="UTF-8"?><process version="8.2.000">
  <operator activated="true" class="select_attributes" compatibility="8.2.000" expanded="true" height="82" name="Select Attributes" width="90" x="313" y="34">
    <parameter key="attribute_filter_type" value="single"/>
    <parameter key="attribute" value="label"/>
    <parameter key="attributes" value=""/>
    <parameter key="use_except_expression" value="false"/>
    <parameter key="value_type" value="attribute_value"/>
    <parameter key="use_value_type_exception" value="false"/>
    <parameter key="except_value_type" value="time"/>
    <parameter key="block_type" value="attribute_block"/>
    <parameter key="use_block_type_exception" value="false"/>
    <parameter key="except_block_type" value="value_matrix_row_start"/>
    <parameter key="invert_selection" value="true"/>
    <parameter key="include_special_attributes" value="true"/>
  </operator>
</process>

Does this process answer to your need ?

Hi again @jabra,

 

Here you can find a new version of the previous process (maybe more adapted to your need) :

Hi
The easiest and the fastest way is to define a special roles for other columns except the one you want to cluster. In this case you would not need any select attributes, joins etc. You can do it because RapidMiner uses for any analysis (including clustering, classification regression etc) only the regular attributes. 

 

Just put Set Role operator and type in "target role" (define your own role)

Hello
Dear Friends
I use the process document from data operator. I want to have columns in the tokenize of words in addition to the main columns and labels and clustering.
How to change
Thank you for helping me too
Thankful

jabra

Hello
Very much of the process you sent. Thank you
Just dear dear engineer
What if I want to see the results of tokenize in the output? As our friend's question is (@ elena2020chao)

And how to evaluate the outcome?
See error

Thanks again if you send the process

jabra

Hello
Has anyone ever done this? Who can help me? I need very much ...
Thank you so much if you help me

@jabra You have nominal values in data set that the performance operator can't use. 

 

You need to convert everything to a numerical value. 

jabra

Hello
Thank you
But
I am clustering on the text field
What should I do?
Thankful
