hello,

While learning about KNN I came across:

My confusion arises from the part in the red rectangle.In the case of k = 1 we are comparing the distances from all the other data points and selecting the minimum one.

In case of k = 3 we calculate distances from data points,select the 3 points which have minimum distance and then among those 3 the point whose distance is minimum,it’s class is assigned to the data point.

Since ultimately we are selecting only one class label for the data point via using the minimum distance method,what essential difference does the value of k bring out??

Can someone please help me understand this??
