Linear regression (https://en.wikipedia.org/wiki/Linear_...) is a fundamental machine learning method that combines simplicity with the power to express a lot of what we observe in the real world. If you want to dip your toes into deep learning, but it seems a little overwhelming, linear regression is a great place to start to get some of the necessary prerequisites.
