Explanation of KNNClassificationModel.java ?

ademuchlis · September 2019

hi,

I know Rapidminer have documentation about the KNN algorithm in the following link

which means the KNN algorithm is also derived from the Java project right ?.

can anyone explain the algorithm in a simpler language ?, maybe like Pseudocode? or easier to understand.

because I see a slight difference with the usual KNN algorithm. I have asked the difference here.
https://community.rapidminer.com/discussion/55963/how-rapidminer-handle-same-distance-for-knn-algorithm#latest

Or can it be said that if there is an equal distance, then Rapidminer takes a label that is in the same order as the first queue?

thanks in advance for your help..

hi @ademuchlis - as @IngoRM suggested in the other discussion you posted, I would strongly recommend digging into the open-source code if you want to explicitly verify the way that k-NN is implemented. It is the only way you will understand everything at this granular level. I am re-posting the link that @IngoRM shared in your other discussion here:

https://github.com/rapidminer/rapidminer-studio/tree/master/src/main/java/com/rapidminer/operator/learner/lazy

You will see the exact java code:
