Efficient AI
Training-free, plug-and-play methods. I would rather find a win you can bolt onto a system that already runs than one that only pays off after another round of training.
I'm a computer science senior at UNIST, working on efficient AI.
This September I'm staying on for my M.S./Ph.D. at the Ubiquitous AI Lab with Prof. Taesik Gong, where I've already been doing research as an undergrad since January. The part I like is getting a model to do more without paying for it twice: methods that need no extra training, that drop into a system already running, and that pass work between the device and the cloud when that helps.
Lately that has meant GUI agents. They can operate real software on their own, which is impressive right up until you notice every step is a full model call. I'm writing my first paper on cutting that cost while keeping what the agent can actually do.
A line I keep coming back to: “If you seek death you will live; if you seek life you will die.”
It comes down to one stubborn fact: the models that work best are usually the ones you can least afford to run, and most of that bill lands at inference time.

Shaping a model around a particular user or device without retraining it from scratch for each one. In practice it leans on the same efficiency tricks.
One working paper for now. Anything that gets published will show up here.
Undergraduate research with Prof. Taesik Gong, Ubiquitous AI Lab
Early work on cutting the inference cost of GUI agents. I'll post a preprint here once it holds up.
A few things I've built, in and out of the lab.
Hansol Deco Season 3 AI Competition
A retrieval-augmented LLM that drafts accident-prevention and response plans for construction sites, built with RAG and a lot of prompt iteration.
2024 Environmental Data Contest
A model that estimates particulate-matter levels at a given location from nearby monitoring stations and fugitive-dust data.
Wooden-craft maker
Ran the operation end to end, from 3D modeling and CNC machining to listing and selling the pieces online.
Ubiquitous Artificial Intelligence Lab, UNIST
Incoming this September to work on efficient AI, personalized AI, and edge-cloud collaboration, advised by Prof. Taesik Gong.
UNIST, Ulsan, South Korea
