Recorded at H2O World India, this panel brings together four H2O.ai Kaggle Grandmasters, Shivam Bansal, Parul Pandey, Chunming Li, and Pascal Pfeiffer, for a wide ranging conversation on competitive data science. They discuss what it takes to reach Grandmaster status, the personal sacrifices involved, and how skills built on Kaggle, remote collaboration, structuring open ended problems, timeboxing, technical writing, carry over into building H2O's own LLM products. The session closes with audience Q&A on breaking into a new domain, starting out on Kaggle, and the impact of LLMs and AutoML on competitive data science.
