AI data restriction: Using AI to analyze, interpret, or process the challenge data is strongly discouraged because the challenge assesses how well teams understand the dataset’s underlying structure and relationships. AI tools may still be used to write, explain, or debug code that processes the CSV files locally. Teams will be evaluated on their understanding of the data and must be able to explain their analysis and conclusions.
