Hi Jozef,

 

You can check the last webinar by @sgenzer. Although there are some web scraping and API concepts that maybe you don't need, two techniques for classification of chatbot conversations are introduced: K-Means clustering and LDA. They surely apply to your problem.

Hello
Thank you so much for your answer

Did i get it right? Should I kmeans comments on clustering? And then apply any LDA cluster?
How do I figure out what content is there in each cluster?

(Is it possible to view the shape of clusters and centers?)
Thanks if you help me:smileyhappy:
Waiting...

Hi Jozef,

 

I'm not sure I understand the questions, but K-means and LDA are two different techniques. Both will assign each sample to one of the clusters. I'm afraid that deciding which to use and with which parameters is problem-dependent and requires a good dose of trial and error.

 

Regarding the visualization, that would be possible only with two dimensions (like the classic example of the iris dataset).

Sebastian

Hi,

thanks so much for your friend @SGolbert

I want to be able to know what content is in each cluster. Can I understand by LDA? How can I use LDA to find the best K? Thanks if you help With respect
