Hello friends,
I need some help.
I need to know how I can find the cluster centroid of each cluster, if
as

Also, k-mean under which classification techniques eager or lazy classification learning? or It’s Unsupervised

Lastly, in case of comparing between Eager and Lazy classification methods, what are they?

@NadaG.Youssef,

  1. Cluster centroid is found by finding the mean of all the observations. In this case, it would be mean of x and y values.
  2. KMeans is Unsupervised because it can work without labeled data.
  3. KMeans is a clustering algo not a classification algo. KNN is a classification algo.
  4. For Eager vs Lazy learning, check out this link http://lmgtfy.com/?q=eager+vs+lazy+learning

On a lighter note, I’d suggest you to first make an attempt to Google your doubts before posting them in the discussion. That would save a lot of time and will make you learn even more.
