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.
I even developed a restaurant recommendation app by collecting lists of famous restaurants and blogs from all over the country :) (It failed miserably...) Now, I am a PhD student researching artificial intelligence.
