I want to cluster into a tweeter. What is the best clustering method for Twitter data?
And that
How to reduce the dimension?
And in clustering we do not have metrics like recall. How to measure the goodness of clustering? And, for example, compare two clustering methods. ?
And how can I predict which cluster is there for new data?
Someone help me
I thank you very much
