Matrix Multiplication — Topic 19 of Machine Learning Foundations

In this video from my Machine Learning Foundations series, I’ll demonstrate matrix multiplication – the single most important and widely-used mathematical operation in machine learning. To ensure you get a solid grip on the principles of this key skill, we’ll use color diagrams, calculations by hand, interactive code demos, and an applied learning example.

This video have cleared my most of the doubts about linear regression
The video is get intuitive.
Thank you so much. You are awesome ❤

Thanks Jon for making these videos. It's been really fun to refresh my math with you. I'm excited to keep going and learn more about machine learning. Thank you so much for the work you've done to contribute to the learning of others.

new subscriber jon love tje explanation and the video thank you for putting this out here. hope u get more subscribers!

came here from Coursera to solve my doubts and now i think ill complete my rest of machine learning course w your videos. thank you

Shouldn't it be (at 6:05):?
A = np.array([[3, 4], [5, 6], [7, 8]])
b = np.array([[1], [2]]) # instead of: np.array([1, 2])
np.dot(A, b)

This is strange, I never understood this in Python, which version is the correct one.

The year I guess was 1988 when I was in year 12 and that time I was enjoying doing this matrix multiplications using paper and Pen. Little did I know, after 34 years I will be learning same stuff from Jon and implementing it using Numpy, PyTorch and TensorFlow.
I am pleased I have covered half of the videos. I am going stop for today. Again I have same question was it not possible for TensorFlow to overload the methods for Matrix-Vector and Matrix-Matrix multiplication?

The part on house prices you were showing at the end, was that forward propagation? wow I've never seen it like that

[lottedeniet]

what's the reason for using torch and tensorflow for the operations up until now, when numpy can also perform them?

[tarunakhari]

so the dot keyword or matmul is inbuild here and automatically gave the dot product of matrix (or matrix multiplication) no algo. to use🤔

It is very outstanding course sir. I love ur method of teaching. May I have ur email or whatsApp.
