The first two sentences of Sec 2.2 are worded in a way that makes them a bit awkward to read. Here are a few suggestions of changes that I think might help:
"in implementation of" -> "that implements the"
"focus in" -> "focus on"
Either add "the" before "clustering problem" or make "problem" plural, whichever is more appropriate
"will limit to deal" -> "will only deal"
remove "any"
"dataset with only real-valued number" -> "datasets that solely contain real numbers"
make "value" at the end of the sentence plural
In this line "suffix" should be "satisfy" or "fulfill".
