title: How does regularization parameter work in regularization?
body: <p>In machine learning cost function, if we want to minimize the influence of two parameters, let's say theta3 and theta4, it seems like we have to give a large value of regularization parameter just like the equation below.</p>

  <p>I am not quite sure why the bigger regularization parameter reduces the influence instead of increasing it. How does this function work?</p>
