Work Experience

Innovation Center Intern

YAMAHA MOTOR SOLUTIONS CO., LTD. XIAMEN | Jul 2022 - Oct 2022

Built a dataset of industrial components with noisy backgrounds, enabling system robustness
Developed an unsupervised image segmentation algorithm based on mutual information maximization loss
Achieved strong visualization performance on the built dataset

Project Experience

Stage-Aware Vision-and-Language Navigation with Enhanced Auxiliary Loss

Course Project | Advisor: Daniel Fried | Fall 2024

Introduced a weighted angular distance loss to improve navigation decision granularity
Developed LLM-based instruction paraphrasing and instruction segmentation for data augmentation
Achieved a success rate (SR) of 53.2% on unseen environments on R2R dataset, outperforming strong baselines such as Speaker-Follower (2018), EnvDrop (2019) and ViL-CLIP (2021)

Improvement on Zero-Shot Text-to-Video Generation

Course Project | Advisor: Guila Fanti | Spring 2024

Investigated frame consistency problem in zero-shot video generation models
Proposed two enhancements: 1) LLM-based prompt elaboration, 2) Few-shot learning for frame consistency
Achieved improved CLIP scores (30.4 - ours vs 29.6 - baseline) on benchmark datasets

A Light-weighted Transformer for Next Word Prediction

Course Project | Advisor: Yuejie Chi | Spring 2024

Designed a lightweight transformer-based model for next-word prediction on edge devices like mobile phones
Applied knowledge distillation techniques, trained on Daily Dialog dataset (21,976 tokens)
Achieved a testing perplexity of 35 and demonstrated qualitative performance comparable to GPT-2
