Topic 3.3 in the last assignment: Finding the most similar tweets with LSH

Can someone explain the second point in the picture how n plane divides the space into 2 power n hash buckets?
Thank you

Hi Naveen_Malla,

This results from the Johnson-Lindenstrauss lemma, as explained here. You can find a formal proof of this lemma here.
Hard to put into plain English :slight_smile:

Hi @Naveen_Malla

In reality the second point is not entirely true:

I think it is used just for simplicity to approximate the number of hash buckets.
