The Difference Between a Simple Machine Learning and a Complex Machine Learning Model?

A very simple machine learning model that people get introduced to is a linearor logistic agression model. And then the more sophisticated ones that you are talking about, say, deep learning, is a more complicated model. We in the end, it all boils down to a bunch of linear algebra, e mo ying, matress, multiflying factor and on. I now t the difference between a simple moto and a compact and a complex modol is really just the amount of lerna algebra computation that you do.
