Hierarchical Agglomerative Clustering [HAC - Single Link]

[@shirleywaller7753]

THANK YOU SOOOOO MUCH!!!!! After emailing my professor, and getting no real help, and spending days trying to figure it out on my own, you saved me! You were very clear, explained very well, and I now was able to complete my assignment. I can't thank you enough for this invaluable help! I wish professors and teachers were all this good!

[@durrotunnashihin5480]

me too.. the video saved me for the last minutes before my exam, thank you so much

[@tusharkumar3828]

Exactly! This is what I was looking for. The Manual calculation and formation of the dendrogram. Thank you ma'am.

[@sabertooth21]

u must watch mahesh huddar video for better exlanation buddy

[@durrotunnashihin5480]

The 3 hours before my exam I saw this video, fortunately single and complete linkage questions appeared on the last part of my machine learning's exam. Thank you very much to this video to get me have a better understanding :D

[@tushar3549]

Thank you on behalf of her

[@adrianacorrea5634]

Thank you so much! You are a star! I have just started MSc after having graduated 20y ago. I am completely lost and you have been a great help.

[@IlliaDubrovin]

The knowledge you are sharing is so rare to find!! You save the world!!!

[@PokemonClassicMaster]

Simple and to the point. The best explanation on youtube.

[@waleedbinowais7624]

The best explanation of agglomerative clustering example on the internet. Thank you so much!

[@sam9620]

thankyou ma'am, the best thing about your channel is that you don't miss any step during calculations which makes it easy to understand 💯

[@danielgetty7216]

I've been trying to figure this out for a couple days for class. Once you showed the MIN(dist) it all clicked. Thank you!

[@adamatkins8496]

Dr Bhatia, you are a gift to humankind!

[@biaoalex2018]

Thank you SOOOOOOOOO much！！ You explained the solution MUCH BETTER than my tutors did, this is so helpful!

[@rafaynaeem7529]

Mam I have watched 3 videos of yours single link, complete link and average link and finally I'm able to understand Thank you mam for teaching us.

[@zeyadahmad4556]

Thank U so much. U helped me understand this Algorithm on the day before my Data mining final Exam =D

[@AnuradhaBhatia]

Thanks for this

[@Surya_Kiran_K]

Thanks so much❤❤ saved a lot of time before the exam

[@mohamedsanogho8361]

this is old, but you just saved another cs student day!

[@maheshasisirakumara4025]

Wow. Clearly explained. Wonder if every lecture has the explanation ability like you

[@AnuradhaBhatia]

Thanks

[@mandeepkhadka388]

Best explanation on Agglomerative Clustering till now, thank you maam!!! I am clear as a crystal now.

[@darshanshah752]

Lovely explanation, I have my masters exam tomorrow, just cleared all the doubts regarding agglomerative clusters, Thank you !!

[@FarhanAli-dq8eh]

Our professor is making us learn this in a softmore data structures class and implement into a project...I thought it felt out of scope for our level

[@abhishekbiswas3420]

thank you so much ma'am, this video really helped me a lot to understand the numerical of agglomerative hierarchical clustering

[@afcmain]

I didn't get the thing that how are you calculating min of distance between cluster and a point

[@alexstefan8479]

I finaly understand HAC MIN. Thank you a lot!!!

[@its_the_yogi]

Really great presentation. I'd like to suggest a minor correction at 04:57 - formula for Euclidean distance ((x-a) + (y-b))^1/2

[@siddhigoyal9362]

Your explanatory skills are amazing ma'am. Please continue making more such learning videos.

[@abhishekchourasia9252]

Very Great and helpful and Very Very Easy Explanation. Understood Each bit. Thank You.

[@mvr192]

Eye opening, thank you very much Anu! Much much respect to you!

[@jyhunter4716]

Thanks Ma'am...wonderful explanation and by this my exam syllabus got sorted...

[@ranati2000]

Perfectly explained the concept.

[@premthapa9959]

The Euclidean distance formula : x is written in place of y. Perfect lecture Very helpful tho ma'am

[@k.m.emonahmed4938]

when I calculated each distance in the calculator by the euclidean distance measuring formula, I have found lots of (0.01) differences in the calculation which can change the whole dendrogram, like in (p3,p2) you calculated 0.15 but it will 0.14.

[@yegavintisumanth5347]

Yes me too got the same (p3,p2) is 0.14 only..It will change the whole dendrogram

[@nathanmcnulty]

Agreed -- the rounding errors in the distance matrix are problematic and should be corrected. Otherwise, those working through this example are likely to be confused when their own calculations yield different results. I would also suggest equalizing the axis scales for the x/y plot. The "stretch" in the x-axis relative to the y-axis is causing a visual disconnect between your calculated euclidean distances and the apparent closeness of points in the plot. For example, the (P2,P4) distance is 0.194 whereas the (P2,P5) distance is 0.143, but the axis scaling makes the (P2,P4) distance look like the shorter of the two.

[@PranavMane-cg1cg]

Bro it's not the fault of sums ,may be it's u ,ur dumb in basic maths so do the 6 7 grade again

[@yukinaproductions5647]

Thank you ! I am studying for my statistics exams. My Unis Documents on this matter are so bad. You really helped me understand it :) On to your next Video :)

[@amargupta7123]

very nice video and easy explanation. Thank you so much, please keep uploading such videos.

[@adamglynn1323]

Thank you so much for this! Need to know this for an exam in 2 days!

[@AnuradhaBhatia]

All the best

[@emmayu4177]

Thank you soooo much for your clear and detailed explanation!!!!♥ Never thought this concept could be so easy to understand!!~

[@swagatmishra9350]

Thank you so very much for the neat and detailed explanation. You have explained each and every step so very clearly.. Thank you very much.

[@giovanni_ferreira]

Splendid approach on your explanation. Thanks a lot!

[@luksb1054]

This is exactly what I was looking for. Thank you so much.

[@Talksofarjuun2405]

Best one thank you so much tomorrow is my exam and now I’m confident in this sum🤩

[@ammarsinan2706]

Thank you, your explanation is straight to the point

[@nasimmatar]

Thank you Anuradha Bhatia, very good explanation i hope to see more of your explanations on various topics related to machine learning and data mining

[@fundamentalslearner7460]

Perfect explanation. Superb

[@abhishekdewang4361]

This teaching was better than my class teacher 😅

[@abhishekadivarekar2269]

Thank you for explaining how to solve this type of sums :-D Looking for more such videos..

[@sampathkengua1507]

What if we got two minimum values as same in distance matrix and then which one to consider first? Time at 5.45

[@Debduttadas1997]

Thank you mem, it is too useful to study the numerical taxonomy . Thanks a lot mem

[@pratheekhebbar2677]

your explanation is too good mam

[@kyeelaquilariaty9234]

Thank you so much it was really helpful for me to prepare final exam :)

[@АлександраМеркульева-т6щ]

Thank you for this excellent explanation.

[@imaadullahafridi1928]

Wonderful explanation and concept delivery, please make more videos like that, Simply brilliant

[@boabdl]

You are a Life Saver. Thank You very much love.

[@AnuradhaBhatia]

Glad it helped!

[@ramankumar41]

thanks a lot ma'am, this is the best !!!!

[@obi6753]

you are a great teacher

[@atkuriajaykumar3701]

thanks madam i dont know how to thank uu .you are doing lot of help means a lot.

[@Mohit-nw5jr]

Awesome explanation! Hope to see more content from you in the future!

[@AnuradhaBhatia]

Hope to see You in VIT, as I am invited as a session trainer.

[@Mohit-nw5jr]

@@AnuradhaBhatia Oh cool that's amazing! We are excited to have you here!

[@stelducam8622]

Thanks a lot for this video. I finally understood how this algorithm is performed. Thanks a lot

[@faizaman9267]

Ma'am, you have roughly drawn the dendogram. If we plot the dendogram by taking Thier respective values on X axis and Y axis, there will be completely different dendogram from what you hav drawn

[@sheikashanurrahman7575]

Very easy and helpful. thanks

[@forumshah4950]

U explained it so easily mam❤️

[@MandeepSingh-ny9ok]

Very good explanation! The quantitative value/level at which the 2 leafs or 2 clusters meet in the dendrogram should be made explicit.

[@mohsala5498]

great Videos Anuradha!!!!!!..... why you're not making any new videos for the last 4 years, your detailed explanation and attention to nuance is so amazing... I suggest you come back with more videos on ML & DL algorithms ...have a great day

[@rashmimbendakaluru7225]

thank u madam, it helped me a lot to understand, its easy, more clear explanation. In the video at 5:03 time, formula is shown wrong, i think a typing mistake. one question having yet is, aft forming a cluster [p3,p6], in the dist matrix, we replaced p3 place with [p3,p6]. why cann't we replace p6 place with [p3,p6]....... thank u adv.

[@ikurious]

Thank you so much, It saved my time a lot

[@mohammedalbluwi2046]

Thanks a lot. You save my life!

[@Vijai777]

Excellent teaching..

[@shreyansjain8028]

Thanks for this video! It was very clearly explained..

[@rabia17417]

Finally I got this ... Thanks a lot

[@jahnavichivukula]

Wonderful explanation. On point👏🏻👌

[@elvykamunyokomanunebo1441]

Thank you for this hand calculation it does a good job of explaining what's going on. Would be useful to get a python code where you do the calculations from scratch using python

[@kiran082]

Excellent explanation.Thanks a Ton

[@ganxiongyong1027]

after lecturer teach me this subject, I definitely not understand what she teach, but after I hear once time then already understand

[@rheaserarodrigues]

Thankyou maam for this video and explanation.... It really helped me❤️

[@andrejborisow9426]

Thank you for your great explanation

[@rachitbhatt40000]

So, what is use of HAC? I mean, how to find the optimum clusters amongst all?

[@otaku5869]

This is still a little comfusing, but I got it so much better now. Thank you!

[@krupakapadia706]

The video is really helpful however I do have a small doubt in regards of a question similar to this but at first there two clusters forming. In that case how to do find the minimum.

[@fag879]

How did the value of [P2,P1] change to 0.24 at 5:36?

[@raufkhamosh8888]

Thank you so much for the best explanation. The link you shared is not working. It would be great if you could share such videos related to the topic.

[@xiaofangchen934]

Thanks. It's pretty helpful. Help me understand how the dendrogram comes on book

[@bobbyyankey5967]

Thank you for the presentation. Have a better understanding of dendograms now.

[@YueHuang_Olivia]

Thank you sooo much. It's a very clear explanation of this content!

[@user-hq8yv9rx9r]

Can you tell me the reason why taking (P3,P6) & (P2, P5), but not P4 & (P 3, P6) with the same 0.15 of distance? ( I am so sorry, I cannot catch your idea in the video for this one)

[@cosmicks7849]

Because (P3,P6),(P2,P5) is coming first in the distance matrix than P4,(P3,P6)

[@vishnusudharshan4453]

Madam Anuradha, can you please show the dendrogram on the graph rather than showing the points?

[@shvang8]

Very nice explanation Keep up the good work Glod Bless you !!

[@Niweera]

Thank you madam, this cleared a big doubt I had.

[@arifromadhan2515]

thank you for explaining....

[@mohamadhallak8644]

It is really useful. Thanks a lot

[@payelbanerjee9192]

mam , i have another question what is the space and time compelxity of this algorithm ?

[@MayankKumar-qp5yy]

Very nicely explained

[@ahmedelsabagh6990]

Very clear and helpful.

[@akshitagarwal98]

Thanks, Ma'am. I like your teaching methodology.

[@230489shraddha]

Brilliant !! Very helpful

[@templar273]

Amazing explanation, i thank you so so so much!

[@sneha.tiwari]

Hello ma'am, I've one doubt, as in the first step, if we get minimum value at three places, then which two points will be chosen to form a cluster? For example, the min value is 2 and is between A,B and A,C and D,E Then in a first go, can we put ABC and DE as two cluster together?

[@fatamatojjohora3755]

Well explained .Thanks a lot.

[@uarangat]

Many thanks mam. Nice tutorials

[@ramyaby977]

Great explanation madam! Thanks a lot!! Could u pls tell the reference book for this?
