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

Hi Data Science enthusiasts πŸ‘‹
.
Today, we are gonna talk about broadcasting in NumPy πŸ”’
.
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 πŸ‘Œ
.
However, if it’s used by mistake it can create bugs and a lot of headaches πŸ€•
.
That’s because in NumPy, you can easily do operations between matrices even if they don’t have the same shape πŸ‘Œ
.
NumPy β€œbroadcasts” the smaller matrix (if valid for the operation) and repeats the operation per element, row, column, etc 🀘
.
In today’s 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.
