From bionic arms to machine learning researcher
Benjamin Choi built a mind-controlled bionic arm as a high school student in Virginia, and it made him realize something critical about human brains: they’re noisy. Brains constantly send out all kinds of signals regulating everything from breathing to hunger to planning one’s daily schedule. For his prosthetic to work, it needed software that could filter out the noise and recognize the signals specifically intended to manipulate the arm.
