Jinyoon Kim

I am currently pursuing my Master's in Computer Science at the University of Virginia, advised by Professor Yen-Ling Kuo. I received my Bachelor's degree in Computer Science from Penn State University in 2024.

My research interests are at the intersection of Embodied AI, Computer Vision, and Language. I am particularly focused on developing intelligent robotic agents that can seamlessly interact with and assist humans in complex, photorealistic environments. By leveraging foundations in 3D vision, multimodal learning (LLMs/VLMs), and Reinforcement Learning, I aim to build robust decision-support systems for mobile manipulation and assistive robotics.

Previously, I extensively worked on automated medical image analysis and self-supervised learning systems, publishing several papers on uncertainty-aware segmentation and spatially coordinated attention mechanisms. I am now translating these insights into the robotics domain to improve agent reliability and human-robot collaboration.

Projects

Text-Guided 3D Scene Editing: Volumetric Removal & Generative Addition (2025)
Jinyoon Kim, Sansshita Baskaran, Manvitha Sunireddy [ report | presentation | code ]

Developed an end-to-end pipeline for editing unbounded Mip-NeRF 360 scenes using 3D Gaussian Splatting.
Engineered a custom "Occlusion-Aware Lifting" algorithm to bridge 2D semantics (GroundingDINO + SAM 2) with 3D geometry, enabling precise zero-shot object selection.
Integrated LaMa for multi-view consistent inpainting (removal) and GaussianDreamer for inserting generative 3D assets (addition), solving the "Artichoke Problem" in volumetric editing.

A Reinforcement Learning Pipeline for Financial Reasoning (2025)
Jinyoon Kim, Scarlett Yu, Donggen Li [ report | presentation | code ]

Developed a comprehensive ablation study comparing Deep Contextual RL (PPO, GRPO, RLOO, DPO) against Heuristic Bandits for the FinQA task.
Engineered a "Discriminative Reranking" pipeline to bypass generation failures, successfully training Llama-3.2-3B and TinyLlama-1.1B models.
Demonstrated that RL provides massive gains for weak learners (+35% accuracy on 1B models) while establishing the "SFT Ceiling" effect on capable 3B models.
