Bennett won (tied with Seok) the 2021 Quinlan competiton, the prediction challenge consisting of 4 problems. He has used neural network which was first time in the history of data 101 that someone used NN so succesfully.
Below, what Bennett said about himself
"Hi my name is Bennett Garcia and I'm a sophomore studying Computer Science and Math. I'm interested in Machine Learning and I plan on pursuing a career in research. I want to work on new reinforcement learning algorithms and develop practical uses for the field. I took Data 101 to further my knowledge on statistics and to practice applying Machine Learning to real problems. Before taking the class I had some experience with Machine Learning, but only on the implementation and Computer Science side. The prediction challenges were super fun and gave me a chance to try using Machine Learning in a more applicative way. I really enjoyed the class. It definitely gave me experience that will help me in my career"
