K-means clustering: how it works
Full lecture: bit.ly/K-means
The K-means algorithm starts by placing K points (centroids) at random locations in space. We then perform the following steps iteratively: (1) for each instance, we assign it to a cluster with the nearest centroid, and (2) we move each centroid to the mean of the instances assigned to it. The algorithm continues until no instances change cluster membership.

seriously, best K means explained
Thank you! My prof tried to explain this in 1.30h. You did it in 7 minutes and I understood it even better.

This is because your brain is already primed to learn and knows what it understands and doesn't understand about the topic.

Awesome explanation. Good and clear introduction with the theory and a perfect example afterwards. Many thanks to you sir.
So much better than the official university explanation. Thanks a lot for this work!
Fantastically clear and uncomplicated description of k means clustering.
This is the best K-means explanation i've ever seen! Great job, thank you!
finally, someone who explained it step by step and visually, thanks a lot!

Victor Lavrenko if you have categorical data what should you run if not k means??

With categorical data the notion of a "mean" or "centroid" is not so straightforward. You could use the mode (most frequent attribute value) instead of the mean. Or use agglomerative clustering, which does not require you to instantiate centroids.
Short, Simple, Complete, and to the point. I love it and it helped me understand quickly!
Clear, easy to understand, the last step by step images with the points and triangles really helped. Really good video, thank you.
This is the clearest explanation of K-means clustering I have seen. I will be modelling my explanations off of yours. Thank you!
I appreciate the simplicity of the explanation. Very easy to understand. It saved me time.
One of the best explanations of K-Means clustering. Thanks!
Sir, you made it so simple. Thanks. After searching a lot, finally this video made my concepts clear.
Best explanation on youtube, don't lose your time looking somewhere else.
Best 7 minutes spent to understand! Thank you
Best explanation ever, hands down. I applaud you good sire.
This kind of stuff on youtube makes my life so much easier.
1000% clearest k-means explanation out there
I've got professor in university who's got PhD in Machine Learning and MS in whatever but he doesn't seem to teach as good as you. Best explanation of k means on internet!. Thank you very much
Best explanation ever. Reminds me of the bubble sorting method, where you sort nearest vector points until no more sorting is needed.
This was the best explanation I have ever seen! Thank you so much!!
Excellent .. couldn't have been presented any more clearly. Thank you!
Legendary explanation, with an invaluable example! Thank you Victor
Great explanation. Just saved myself 20 min figuring out my course notes!
Thank you victor, that the best tuto about the K-means I ever watched....

It's 2021 now, this video is still much much better than my prof's class
Learned from many great resource but this is definitely one of the best open to all explanation of all.
One of the best ever videos on K-means. Please carry on your amazing work .

Clear as much as it can be. It has been useful. Thanks.
Clear, brief and excellent. Many thanks VL.
Thank you! It was the best intuitive representation of K-means!
I cannot speak such fast and clear at the same time. Nice!
The example at the end was very helpful, thanks for the video
Just the best explanation heard so far! Good job
Thank you Graham Norton! You’re the best!
Very clear explanation and presentation. Thanks for you time and effort!
The BEST VIDEO explained K-men EVER ... Thank youuuu
Wow this is Soo well explained... 7years later it's still🔥🔥🔥🔥
Very good Mr.Lavrenko, thank you, well done!
Excellent explanation, Victor. How lucky must be your students. Greetings from Mexico
Really good explanation! Thank you :) Greetings from Germany
Thank you. you made it clear with example Lets cluster out those 108 downvotes
Fantastic video, broke it down very clearly. Thanks a lot.
Thank you for the help!!! I'm just learning all of this and this video is realy helpful as far as getting a conceptual understanding of all this

Well explained Victor, thanks for your sincere effort.
The visualizations used are super helpful!
That was brilliant, I understood it straight away.
That really helps me, thank you Victor!
Great diagrams and explanation. Perfect!
This was so helpful! Thank you so much!
Whaaaa. I got k-means in 2.5 minutes! This was amazing!
I wish the lecturer i have at uni was as good as you prof Victor.
Thank you so much for the video. You have made it very clear and simple.
Awesome explanation, thank you Victor!
Thank you very much. Best explanation so far
Thanks. this was very helpful. Glad to have found a video that explained it in a manner that didn't take too long to get the message through. By the by, your voice reminds me of the character Pritchard from Deus Ex: Human Revolution. Sorry if you get that a lot.
Victor, That was excellent!
Thank you sir, for sharing the video, it's helping me a lot!

Thank you so much. Now I understood it at last.
What an outstanding presentation 👏👏
Bravo!!! Well explained & Thank you
This is awesome! Thanks for your explanation!
Great and clear explanation. Could you possibly add a video of the formal proof of why this algorithm always converges?
very nice explaination ,very clear and concise.thank you very much
great explanation, simple and visualized. Thanks! =)
wow, what a clear explanation! thanks man!
