Engineering Engineered Features and Creating New Features

I think also coming back to this feature engineering and creating new features. I think by doing that you also learn about learn more about the business. So for example, I work at the leaks and this is like online marketplace. We have sellers who have buyers, and they exchange goods on the platform. And we look at the raw data and we created a feature called meaningful conversation. This gives us a lot of knowledge about what happened. By engineering the feature we were able to understand the business process better. It's really hard to get rid of the co linearity from the original feature set. Well, now we've got great tools to help us with that analysis.
