How do I select features for Machine Learning?

Selecting the "best" features for your Machine Learning model will result in a better performing, easier to understand, and faster running model. But how do you know which features to select?

In this video, I'll discuss 7 feature selection tactics used by the pros that you can apply to your own model. At the end, I'll give you my top 3 tips for effective feature selection.

Hey, Kevin, your content is great. I did a whole project by taking help solely from your content 😊

One thing about this guy is that he gives very deep insights which you'll get nowhere else. As much as possible he'll give best practises, I have observed this from way back in the pandas course. Thanks so much Kevin. Please do deep learning and in-depth feature engineering tricks in a future video.

Thank you so much Kevin! Your response was very succinct and clear! I actually showed your video to my colleagues during our machine learning Friday sessions at work and we all loved it. It was a timely topic for us since we’re all fairly new to building ML models.

Great tutorial and the way you simplified entire dimensionality reduction aka feature selection is awesome

[achmadrifkiraihansyahbagja]

Your channel is great!! The videos are great for beginner and people whose English is not their native language because your voice is sooo clearrr to understand.

[ahmarhussain]

great explanation. no extra unnecessary stuff

Unfortunately Most underrated channel on YouTube.

[yunes]

Lot of insights in your lecture. Thanks

[saragorzin]

Thank you for your great and helpful videos

[djamila]

easy to understand your explanation thank you !

Feature selection and labelling is key, so what steps we can take ?

1) Focus on question : What does it or you want, there may be so many features what matters to you most then drop the useless features for that project.
2)Visualize the data and plot .
3)Backtestting model : If time is not factor try various features and see the output.

Really good tips for feature selection.

Awesome lesson! This topic is quite important in text classification while the number of words and phrases extracted from text are somehow overwhelmed.
