          <p>大学是新的起点。在大学里我希望得到的不仅仅是知识的积累，我更希望能在大学这四年的时间里培养出独立思考、分析解决问题的能力。而这两年以来，我也一直在不断地探寻着出路。<strong>“生活中的控制”</strong> 这门课，我认为它就是这样的一堂课，注重培养学生思考，并且对于学生生活的规划给以启发和指导，是非常有意义和价值的课程。</p>

We can read <a href="https://blog.mybjut.cn/2019/03/15/What-is-Machine-Learning">authoritative definitions of machine learning</a>, but really, machine learning is defined by the problem being solved. Therefore the best way to understand machine learning is to look at some example problems.</p>
