np.tile() is one of the most beautiful yet super useful functions there is in NumPy and Python! Happy weekend!! ππ
.
Typo alert: 4th slide should say np.array([[6], [7]]) for the picture to match!

Hi Data Science enthusiasts π
.
Today, we are gonna talk about broadcasting in NumPy π’
.
Broadcasting is a powerful, useful yet tricky feature in NumPy. If you know it well and use it intentionally, you can simplify a lot of code π
.
However, if itβs used by mistake it can create bugs and a lot of headaches π€
.
Thatβs because in NumPy, you can easily do operations between matrices even if they donβt have the same shape π
.
NumPy βbroadcastsβ the smaller matrix (if valid for the operation) and repeats the operation per element, row, column, etc π€
.
In todayβs code snippet, a scalar broadcasts into the same size of a matrix to be subtracted. Similarly, a row and column vector broadcasts into the right shape before getting subtracted!

Partitioning is an important technique when you have a large amount of data and like to partition it based on a pivot value. NumPy can do this very efficiently and it leads to some cool applications.
