Yi Yang

  My name is Yi Yang(杨益), a sophomore at the University of Science and Technology of China. I major in Statistics and minor in Communications at the School of the Gifted Young. I am passionate about bridging the gap between Statistics, AI and Social Science, as I believe that these fields can work in tandem to solve complex real-world problems.
  This passion has motivated me to delve into the research of machine learning since my freshman year, with a specific focus on Graph Neural Networks. Currently, I am interested in exploring topics related to scalable GNNs, generative models, as well as the associated privacy and security concerns.

Studies & Hobbies

Here are some daily reflections available that aim to inspire more people.

  • Arxiv Reading

      To stay abreast of cutting-edge science, I've cultivated a daily habit of dedicating 30 minutes to reading the latest ML papers.

    Blogs and Seminars

      I've actively participated in many academic lectures, read blogs and classic AI literature to stimulate my thinking and exploration.

  • Literature,Philosophy and Music

      On my personal journey, I have always nurtured an unwavering passion for literature, a flame that burns brightly within me. Currently I have a profound interest in postmodernism and psychoanalytic works, especially Virginia Woolf and Carl Gustav Jung.

      Folk music has always held a special place in my heart. It serves as a lens through which I witness the rise and fall of nations and contemplate the universal struggles faced by ordinary individuals, provoking profound reflections within me.

    Famous open courses

      Exploring distinguished humanities courses allows me to rekindle the humanistic passion deeply rooted in my childhood memories, while remaining vigilant to ensure that my ideals are not eroded by the trivialities of daily life.

    Exercise

      I maintain a regular exercise routine that includes activities like running, fitness training, swimming, and more.

Education/Research
Experience

Below are my Education and Research Experience

University of Illinois at Urbana-Champaign(UIUC)

June 2023 - present, Research Intern

Advisor: Jiaxuan You

During this stage, I hope to explore and can contirbute to some of the current focal topics in GNN, such as scalability, expressiveness, and interpretability.

Lab for Data Science

May 2022 - April 2023

Lab for Data science is where I began my research in machine learning, advised by Prof. Xiangnan He. I am honored to have conducted research exploration and participated in a project on graph unlearning with Dr.Jiancan Wu.

University of Science and Technology of China

September 2021 - present

I was accepted into the School of the Gifted Young during my second year of high school, and I am deeply grateful to USTC for providing me with an early opportunity to experience higher education.

Miscellaneous

  During my high school and university years, I endured a prolonged and arduous period of confusion where I felt that my dreams and talents were overshadowed by the relentless pressures of reality. Regrettably, I found myself gradually assimilating into the realm of societal excellence, yet losing sight of my unique individuality.
   However, as time passed, I came to realize that genuine liberation can only be achieved by passionately pursuing what truly ignites my soul. It is my earnest desire that these words resonate with those who find themselves enveloped in the haze of uncertainty. Once again,I extend my deepest gratitude to my loved ones for their unwavering presence and steadfast support throughout it all.
