Guys could you please help me by providing any resources or better explain how to visualise the cost function and feature scaling for multiple linear regression.For example the contour plots in feature scaling I am stuck!And how can anyone represent multiple features in a space i understand they are using vectors and it’s certainly not 3d graph may in space R^n…
You can only make a plot in 2D (for two features), where the contour lines represent equal cost curves.
The human vision system cannot cope with more than that.
Akshay - perhaps try looking up Engineering Stats videos or short classes. Or Quality Control videos. Both have similar concepts to cost function and feature scaling but may explain a little differently and might help you.
