Luca is a Research Scientist at Amazon, and previously, he was a Senior Economist at Zillow. We discuss everything from getting a job, assessing your prospective manager, and building predictive models to getting buy-in from stakeholders as a scientist.
As a data scientist, you need stakeholders’ buy-in for your work to make an impact. Non-technical stakeholders may be the hardest to convince, as you need to provide an intuitive and detailed explanation of how your model works, why they should trust the model’s output, and the risks associated with your chosen modeling technique.
For example, if your task is to predict customer demand, you can test your predictive model accuracy out of sample and track the model’s accuracy over time. However, accuracy metrics alone don’t explain why the model works or doesn’t work. In this podcast episode, Luca and I discuss how to choose modeling techniques when faced with a non-trivial forecasting problem and how to effectively present results to stakeholders.
