Martin Wattenberg: ML Visualization and Interpretability
The Gradient: Perspectives on AI
Opportunities for Dashboards and Interaction Design
The chapter discusses the opportunities for dashboards and interaction design in relation to language models. It explores the need for true interface innovation and the importance of transparency in user interfaces. The chapter also delves into the challenges of current interfaces and the lack of a clear vision for future interaction patterns.
In episode 99 of The Gradient Podcast, Daniel Bashir speaks to Professor Martin Wattenberg.
Professor Wattenberg is a professor at Harvard and part-time member of Google Research’s People + AI Research (PAIR) initiative, which he co-founded. His work, with long-time collaborator Fernanda Viégas, focuses on making AI technology broadly accessible and reflective of human values. At Google, Professor Wattenberg, his team, and Professor Viégas have created end-user visualizations for products such as Search, YouTube, and Google Analytics. Note: Professor Wattenberg is recruiting PhD students through Harvard SEAS—info here.
