Hello Bioinformatics lovers,

how does PCA projection work? How do KNN and MNN for label transferring work in Seurat?

As promised yesterday, I wrote a long blog post on how I attempt to understand it at a low level.

I spent at least 6 hours on it even with the help of ChatGPT:)

Read it here! https://divingintogeneticsandgenomics.com/post/pca-projection/​

Hope you enjoy it.

Happy Learning!

PS:

If you want to learn Bioinformatics, there are four ways that I can help:

1. My free YouTube Chatomics channel, make sure you subscribe to it.
2. I have many resources collected on my github here.
3. I have been writing blog posts for over 10 years https://divingintogeneticsandgenomics.com/​
4. Lastly, I have a book called "From Cell Line to Command Line" to teach you bioinformatics.

Stay awesome!
