Predicting Human Trajectories by Learning and Matching Patterns

Abstract

As more and more robots are envisioned to cooperate with humans sharing the same space, it is desired for robots to be able to predict others' trajectories to navigate in a safe and self-explanatory way.We propose a Convolutional Neural Network-based approach to learn, detect, and extract patterns in sequential trajectory data, known here as Social Pattern Extraction Convolution (Social-PEC).First, my supervisor, Dr. Jean Oh. She believed in my potentials when I had little to no experience in this research area, and offered me the opportunity to work with her. In the past two years, she almost gave the perfect amount of flexibility and guidance for me to explore and to focus. Beyond my research work, she also genuinely cares about my personal well-being and future career goals. She always asks us to have enough rest and take breaks and vacations, she encouraged me to take internship and pursue career directions that I am passionate about even when they are not aligned with the lab's interests, she sacrificed her personal time to meet with me daily in the beginning of the quarantine to motivate and encourage me when I needed it the most... I will never forget all of Jean's kindness and support to me. Second, Dr. Red Whittaker for offering me the full-time position where I started my journey in CMU; Dr. John M. Dolan, Dr. Kris Kitani and Dr. Chieko Asakawa for trusting me and hiring me when my positions keep being terminated for various uncontrollable factors. Third, Dr. Ji Zhang for helping me with robot building with his expertise; my lab mates Sam Shum, Advaith Sethuraman, Felix Labelle, Brendon Bolt, Xinjie Yao for their assistance and inspirations to my research.I also would like to thank my parents for all of their sacrifice, investment, expectation, support and love for me; my dearest roommates/landlords/best friends in Pittsburgh, David and Allison Lambacher, for taking care of me like a family whenever I am in need; friends from my small group and my church North Way Christian Community, for all the good time and spiritual support and accountability that I needed.Lastly, I have to give all credits to God, who created me, forgave all my sins, and loves me unconditionally.
