Regularized linear regression model to predict the water flow from a dam | Examined effects of bias vs variance

Implementing regularised linear regression and using it to study models with different bias-variance properties. Insights for applying machine learning.

Here, we implement regularized linear regression to predict the amount of water flowing out of a dam using the change of water level in a reservoir. In the next half, we go through some diagnostics of debugging learning algorithms and examine the effects of bias v.s. variance.
