Agglomerative Hierarchical Clustering Single link Complete link Clustering by Dr. Mahesh Huddar
This video discusses, how to create clusters using Agglomerative Hierarchical Clustering for the given data point?
Consider the following set of 6 one dimensional data points: 18, 22, 25, 42, 27, 43
Apply the agglomerative hierarchical clustering algorithm to build the hierarchical clustering dendrogram.
Merge the clusters using Min distance and update the proximity matrix accordingly.
Clearly show the proximity matrix corresponding to each iteration of the algorithm.

Sir what is the relation between distance threshold and no of clusters? Is it inversely proportion?
Awesome way of explanation! Legend.

great explanation. i wonder what is the stop condition to define final clustering- the algorithm can run until all points are clustered or it can stop at an optimal point no? what is that point?
Wow. You made it very easy to understand. Thank you Sir

2:53. Sir i am not particularly understanding what you did from here. You told the 27th row and column to be removed but instead you merged taking out minimum value among those 2

Yeah there should be 17 instead of 15

I think it should be 15 only sir has done the question with taking min instead of max for the linkage please do correct me if am wrong

Even I got the same confusion. I retained 17 out of 17 and 15 for row containing 25 and 27, thereby deleting row and column of 27 . So, for Step-3, the value under column and row containing 42 and 43 is 17 instead of 15 as mentioned here in the explanation.
thank you my friend, very explanable :)

Sir how can we identify it is single link or complete link structure?

if we take min distance between 2 points while clustering then its single if we take max or higher distance between 2 points then its gonna be complete

after removing 27th row , there should be 17 not 15

It should be 17. after removing 27 column and row , 25 row and column values will remain right? Pls tell the correct one

As 25 and 27 are in a same cluster, 15 is correct because 42 is greater than 25 and 27, so distance of 27 to 42 is 15… If it was less than 25 and 27, lets say example 20, then distance between 25 and 20 would be taken which is 5
Need CURE algorithm
what if 2 distance points are same how will we merge
@skarthikeya5285

its a sequential processes so which ever one you calculate first will get merged first thats how it works in programs so you can do the same in numerical examples
