Curse of dimensional mostly occurs in algorithms like KNN which completely depends on distances. High dimensional spaces are obviously largely and points in such spaces disperse from each other. We will evaluate the curse of dimensional with 1000 observations with the change in dimensions.

Let us import the libraries

Let us generate random numbers between 0 and 1

Now we will calculate root mean sum of squares of Euclidean distances

Let us calculate the distance

Now we plot the observations

The output of the observation is given below
