AI
Fascinated by the subject, I then chose a Machine Learning course in the third quarter, where I explored reinforcement learning. Together with a roommate, we developed a multiplayer video game to integrate our AIs: his was based on a neural network, and mine on a variant of Q-Learning. I have fond memories of nights spent in the library optimizing our AIs (defining the right rewards, the right exploration ratio, etc.).
