about clustering
Hello
Excuse me a few questions about clustering the text 1 I did the clustering of the text. I did tf-idf first then kmeans 1.How do I find the center of each cluster? Can the central sentence of each cluster be found? How?
2. In the table of cluster centeroid, I have these values Can anyone say what the higher value means?
3. I have a new text. How do I identify which cluster? Is there an operator? Does anyone have a sample process?
4 How can I cluster with som and predict a new sample cluster? I used som after tf-idf And then the clustering is correct? help me
5.How to after clustering texts. Suggest a text?
I do not know anything about this question and I am a beginner
6.How do I do some parallel clustering?
Thank you

Altair Employeehello @m_keshavarz_com - so the reason I did not reply is that I don't really understand your questions. Perhaps you can take some time and rephrase them?

Hello
Sorry
I am in the clustering and in the use of the beginner's RapidMiner
So forgive me
I want to cluster the check data. And what's the cluster in every sentence?
Then a new sentence entered into which cluster is placed and how accurate the prediction is
I clustered the sentences, but I do not know the rest of the steps on how to do it in RapidMiner
???
And how can I do better with SOM?
If I use pca to reduce the dimension later. Long time is spent
How do I save the pca result and then use it for clustering many times?
How do I do some parallel clustering methods to speed up?
What does the larger number in each cell mean the cluster centroid table?
How do I define the spike center clause in clustering sentences?
Or the word center of each cluster?
I hope I can convey the concept
Thanks
With respect
hello @m_keshavarz_com - have you tried searching on this topic? I think I answered a very similar question about this yesterday!
