About Me

I'm a CS student at UC Berkeley who's currently taking a gap away from school to self-learn with my own curriculmn. This blog is to document and organize my learning.

Jeju Island, Korea

I was born and raised in Seoul, Korea up until middle school, but went to high school in Jeju island-a volcanic island at the southern tip of Korea. I spent a lot of time biking and diving in the waters. Seeing the beauties of the waters made me want to study marine science or physics in college.

A lot changed my first semester there. I took an introductory cs class taught in Snap!(berkeley's version of scratch) with the nudge of a friend and loved it. Maybe it was the combination of having a friend to do fun projects with along with many dorm friends also taking cs classes.

Korean Navy 2020~2022

When covid struck I came back to Korea and served in the Korean Navy. I was on a battleship as a boatswain's mate, but towards the end of my service I met a friend who introduced me to ML. It was a happy combination of science and engineering. After my service, I did my first ML project in underwater CV where I turned my distorted diving photos into ones that were clean.

UC Berkeley - 2022~Spring 2024

I spent most of my time reading papers instead of classwork. I wandered through lots of rabbit holes ranging from monocular depth estimation, multi-agent RL, diffusion, hyperbolical NNs, and GNNs. They were mostly methodology papers, but I realized there's a lot of overlooked engineering that's not specified well in these papers.

I'm taking a gap back in seoul studying the engineering behind ML, especially memory-optimization and efficient scaling methods.

    "In the novelist’s profession, as far as I’m concerned, there’s no such thing as winning or losing…
    What’s crucial is whether your writing attains the standards you’ve set for yourself.
    Failure to reach that bar is not something you can easily explain away.
    When it comes to other people, you can always come up with a reasonable explanation, but you can’t fool yourself.”
