Popular Talks by Margaret Mitchell

Forecasting the Future of AI From What We Know Today

By examining how past priorities in AI development shaped the AI of today, we can make some predictions about how what we prioritize today will shape the AI of the future. In this talk, I will work through how AI (machine learning) systems came to be what they are now, the different biases and values at play throughout the AI development lifecycle, what these suggest for how AI will evolve, and what’s worth focusing on now to create beneficial AI in the future.

Data and Intentionality in Modern AI

Data is a fundamental component of machine learning, serving as the foundation for what ML models learn. However, relatively little attention has been paid to how ML datasets can be collected, curated, measured, stored, and shared responsibly. In this talk, I will dig into these issues, covering details on datasets and data governance, and provide some guidance on how we can use human values to shape what (and who) ML data represents.
