 AI Deep Dives are a great time to deeply explore research problems which might be solvable with deep learning. Here, researchers in other disciplines can discuss their ideas with DSI data scientists, other researchers, DS graduate students, and undergraduate students. Together, we brainstorm and formulate solutions, lay out project plans, recruit students and engage potential collaborators for the goal of initiating new projects, new AI project phases, or new AI project directions.
