Cost Function - Intuition Ⅱ
Let's see a case of regression problem. We can make a straight line of hypothesis($h_\theta(x)$) in this case and it depends on the value of $\theta_0, \theta_1$. Below picture shows cost value which dependes on the hypothesis. Using this graph, we can make a contour plot. A contour plot is a graph that contains many contour lines. A contour line of a two variable function has a constant value a..
