デュセル・ブライアン
I am a computer science researcher interested in natural language processing, neural networks, AI, syntax, machine translation, and formal language theory. I earned my Bachelor's degree in Computer Science at the University of Notre Dame and, after spending some time in industry, later returned to complete my PhD with the brilliant David Chiang. My thesis was about learning syntactic patterns (especially ambiguous ones) by incorporating nondeterministic pushdown automata into neural networks.
