Learner Reviews & Feedback for Machine Learning Feature Selection in Python by Coursera Project Network

Course was useless. Videos of instructor writing out some lines of code, and mispronouncing words he must be reading from a script. The point it is to understand how to interpret and use the results of the code. He simply glances over it with "here's your output!". One example even failed when he used incorrect syntax, and he closed it, and moved onto next example. Another example had him actually saying "well this isn't a good example for this", but then proceeds to teach with this "bad example". Clearly too lazy to put together a good example for a course.

Worst class taken on Coursera - can't believe I paid for it...

There was very little explanation. There was nothing to do for me. How can it be a project centered course! I wonder.

Code snippets showing a number of feature selection and dimensionality reduction techniques that are implemented in Python procedures. Their weren't instructions on how to get the code to run in the Rhyme desktop. However for this course it wasn't that important - I simply wrote down the names of the modules for future use.

Pro : Short and to the point. Within an hour you'll have seen a number of Python feature selection and dimensionality reduction procedures with a short demo for each one.

Con: If you want to use a technique well - you'll need to look it up and see an in depth explanation of the parameters and results. Looked up SelectKBest, RFE, etc. and indeed found excellent articles. BUT you need to first know that they exist and why they exist - and this is why I gave the course 5 stars.

I learning something interesting, we can do many think with python, machine learning, AI

Thanks, I truly appreciate all information

good

The algorithms explained were at superficial level, and not in depth. Also, the codes were not very detailed, with no focus on variable data type. Hope the feedback is useful!

You get the basics on all the feature engineering algorithms you can use but no explanation on what the results mean or how to interpret them. I could have searched all of this up and it would have given me better explanations. Even worst the rhyme.com constantly kept on changing docks for me and I couldn't figure out why either. Definitely not worth the money.

very disappointed! I couldn't find the code for later videos to download, only the first video has downloadable script. There are errors in the script, the dataset Pima has less rows than the original data on UIC. What's the point of paying $9.99 for the bugged code? Each video is less than 5', only 8 videos in this project, not even any slides/ppt to describe/summarize methods... Why I have to pay for a bugged script and get nothing out of this?

C​oursera must check and verify the quality of the projects at first as the learners need to pay for each of them. Despite the project describption ... I could not find any useful points to recommend this project.

Close to no explanation why are things done this way and not different. Certificate can hardly be used as signed by Prof. John Doe

Don't waste your time here.
