    My role model: Christopher M. Bishop

    What my heart tells me:
  • I love machine learning research and will dedicate the rest of my life to it.
  • Whenever a research problem challenges me, my heart starts beating.

    • What I believe: I believe only mathematics.

    What I learned: Any difficulty can be overcome if one does more than doing one's best.
