Some places the code used could have been simplified to be easier for the learner to understand. For example: (eigen_vectors.T[:][:])[:2].T was used in the course video but it can be replaced by eigen_vectors[:, :2]. The second one which I used is much simpler and cleaner to understand.

Thank You.

Did not focus on the mathematics part of PCA. The explanation could have been better and easy to understand.

Muy buena explicación para cada uno de los aspectos del PCA.

I do not recommend taking this type of course, take one and pass it, however after a few days I have tried to review the material, and my surprise is that it asks me to pay again to be able to review the material. Of course coursera gives me a small discount for having already paid it previously. It is very easy to download the videos and difficult to get hold of the material, but with ingenuity it is possible. Then I recommend uploading them to YouTube and keeping them private for when they want to consult (they avoid legal problems and can share with friends), then they can request a refund.

Well, this project seems to be very basic and can be created using WEBSITE LIKE:

https://www.geeksforgeeks.org/principal-component-analysis-with-python/

The platform is really hard to use, the screen is small, and there're lags when I'm typing into the jupyter notebook on the virtual desktop.

Good Introductory project to gain insights into PCA using Numpy and python.

This is a great project. The instructor facilitates clear and practically.

Learned Applying PCA

Concise course.

Liked the method of teaching.
