Jazz and Homesickness

9 minute read

Published:

On a cold January day in 2023 in Nashville, Tennessee, just before heading to the airport, I took a small detour to stop by Nashville Jazz Workshop. The venue was closed, but I stood outside for a moment, feeling as if a smooth piano melody were drifting through the air, quietly comforting my homesick heart. If this pairing of American jazz and my Chinese homesickness catches your attention, I invite you into a very personal story of mine, one that intertwines the life journey of an international student with a particular American jazz pianist. Happy 2026, from my home in Shenzhen, China.

I’m feeling bittersweet because yesterday, December 19, 2025, was my last day at Nike. My six-month research internship culminated in three presentations across multiple time zones. While the details of the work will eventually show up in my MIT thesis next year, here I reflect on this unique journey of conducting AI research at a world-renowned brand.

6.8300 Final Project: Taming CLIP’s Captioning Bias: A COCO-Driven Analysis and Permutation Ensemble

20 minute read

Published:

Abstract: Vision-language models like CLIP struggle with multi-object scenes, often favoring prominent objects or those mentioned first in captions. Using real-world COCO images, we show that CLIP’s caption-matching accuracy drops from 91.23% to 87.45% when object order is reversed. To address this, we explore a post-hoc mitigation: a permutation ensemble that averages scores across all object orders, boosting robustness and recovering accuracy to 90.04%. Our findings reveal persistent order biases and offer a simple, effective strategy to improve CLIP’s reliability in complex scenes.
