K-Means Clustering From Scratch in Python (Mathematical)

In this video we implement K-Means clustering from scratch. We look at the theory and the mathematics behind it and then we use NumPy to put it into code.

this is great, thank you. it feels good to understand something and be a little closer to understanding machine learning or how to use it properly.

I take random points from my data as initial centroids, less computations since you only need the set a random integers for indices.

Hi, thanks for your comprehensive explanation.
I want to use cosine distance as metric instead of Euclidean distance. could you please guide me?
shoud we just change the part of code which calcaulates Euclidean distance or also other changes need?

[SeziManuhutu]

your explanation is great. but i want to ask, what if we want to know what data is move to different cluster. like at first the data is in 0 cluster but then after that it's move to the other group. how do we know the number of data that is move to another cluster?

Beautiful Video!
If I plan to reuse this code, is this code licensed by you (or anybody else)?. If I reuse it I will post a link to this video but I wanted to be on the safer side!

It's a great tutorial. Beside everything, I just didn't understand why and how it was assumed to have 3 centroids for the example dataset where as you assumed the dataset has no label (unsupervised). Appreciate if you can elaborate. Thanks,

Hello, I had a question, I wanted to know if I want to work in machine learning or data science, I must use Anaconda and Jumper Lab or can I use Pycharm? I asked this question to many people and they said I should work in Jupyter Lab I can't get along with its environment. I can work inside pycharm or vscode. Your answer can help me a lot. Thank you

hi i am getting this error can you tell how to solve it
