[Linear Classification] From Linear Regression to Linear Classification

In the posts 'Introduction to Linear Regression', 'Simple Linear Regression' and 'Polynomial Regression and Features-Extension of Linear Regression', we had discussed the regression task. The goal of regression is to find out a function or hypothesis that given an input $\boldsymbol{x}$, the hypothesis can make a prediction $\hat{y}$ which should be as close to the target $y$ as possible.
