What if there are more than two attributes? How would we determine which attributes to take while finding the Euclidean distance?

[@Nothingeverything192]

Did you find the answer?

[@sreedevigovindan2127]

13 th sample distance is 0.608 . So first and 13 th sample same distance. How to rank it?

[@ramavishnu8078]

It is an ascending order

[@sivaprakashkoduri1595]

Wht will we take?

[@dhanushvcse4056]

Sir I have one doubt ... I get first five rank sample if in which two are belong setosa and another two are getting virginica where one more different
In which case what is choose sir

[@MaheshHuddar]

That is an ambiguous state
In such case you need increase the value of k and then make a dicision

[@_feel_good_stories]

sir what if the distance between them are same values for 3 numbers how we have to give the rank to them

[@rahulroyal8321]

I to have the same doubt if you found explain

[@_feel_good_stories]

@@rahulroyal8321simply use other distance formula rather than using euclediansdistance formula

[@beastbaby7946]

this dataset is quite lengthy for this sort of problem!

[@xenon_429]

What of k is not given then what do we do?

[@akankshagupta321]

What if the value of k is 4, do we have to check all the rank before 4 or simply the 4th value

[@schnitzel_enjoyer]

first 4 ranks, most occuring species is your result

[@vaidiksinghrajput3405]

​@@schnitzel_enjoyer what if we r at 4 and 2 have same no. Of iterations

[@afaq715]

If value of K is not mention in this case so what value we take as a K ?

[@birdman2108]

K=sqrt(number of neighbors)
+-1 to K if K is even, make it odd to prevent any ties

[@dazz2469]

sir what if the target value is something like weight where all values are different so after euclidean dist. how can we compare the nearest values because all are different

[@MaheshHuddar]

Watch this video
Here I have addressed both discrete and continuous valued Target function:

what if k is 3 and all 3 are different

[@MaheshHuddar]

That will be an ambiguous state
Either you need to go with distance weighted KNN or Increase the value of K

[@musadayel4673]

how did you the this new example 5.2 and 3.1 because i have checked the table is not there ?

[@jamescrox3372]

That is just a scenario. Just imagine a guy wants to find the nearest neighbor with his data sepal length 5.2 and sepal width 3.1. You can make up anything yourself

How to find k value if not given

[@krnl1304]

K is usually the square root of the total number of samples given.
Otherwise we usually take K as 3.

[@mehrim5309]

I dont understand that..how can we find the column of rank.?

[@MaheshHuddar]

The most nearest neighbour is given rank one, next rank 2 and so on

[@mehrim5309]

@@MaheshHuddar thank u sir

[@harshalgosavi40]

From where we get value of K?

[@ኪራA]

k will be given in the question itself.

B 2 0
He is studying machine learning and encountered some questions which he is unable to
solve. Help him solve the following questions.
1. (2 points) Are the points linearly separable? Support your answer by plotting the
points.
2. (3 points) Find out the weight vector corresponding to the maximum margin hy-
perplane. Also find the support vectors present.
3. (2 points) What is the effect on the optimal margin if we remove any one of the
support vectors in this question?
4. (3 points) In general, for any dataset, what can we say about the effect on optimal
margin, if we remove any of the support vectors
