My primary research areas are data science, reinforcement learning, and deep learning.

I am currently doing crawling and text mining as a hobby :)

I developed an app called Marong that uses crawling to collect and display only popular community posts,

I also created a restaurant recommendation app by collecting lists of famous restaurants and blog posts from across the country :) (it failed miserably..)

I am currently a PhD student researching artificial intelligence.

I even developed a restaurant recommendation app by collecting blog posts and lists of top-rated restaurants across the country :) (though it failed miserably...) Now, I am a PhD student researching artificial intelligence.
