Scaffolding to Superhuman: How Curriculum Learning Solved 2048 and Tetris
Training gaming agents that beat massive search-based solutions on 2048 using a 15MB policy, and discovering that bugs can be features in Tetris.

Research Engineer @RLWRLD with Cognitive Neuroscience expertise
I work in robotics, developing software to teach robots. I also train gaming agents as a hobby, where the principles are similar and iteration is much faster. Many aspects of cognitive neuroscience training seem to transfer - designing evaluation tasks is similar, perception and action “networks” are comparable, and both involve extensive debugging.
During my PhD and postdoc, I used web-based cognitive tasks, brain imaging, eye-tracking, and machine learning to study human decision-making. For example, I developed The Choose-And-Solve Task to show how some individuals with math anxiety choose to avoid math and published my work in Science Advances (Choe et al., 2019).
