Questions & Answers

Q: How can participants access all the resources for the course?

Participants can access the course's public website, which serves as a hub for all the course materials, including policy pages, projects, background materials, and more. It also provides links to the course's Ed forum for discussion, canvas for screencasts and quizzes, grade scope for assignments submission, and GitHub for course code.

Q: Can past course projects be accessed for reference?

Yes, there is an index of past projects available behind a protected link, accessible to enrolled participants. Additionally, there is a list of published work on the course's GitHub page, which includes downloadable projects and course submissions.

Q: What is the significance of benchmarks and evaluations in the field of AI?

Benchmarks and evaluations play a crucial role in AI research. They serve as measurement instruments to assess the performance, progress, and capabilities of AI systems. They also enable comparison between different models, facilitate new capabilities through training and testing, and contribute to scientific inquiry and understanding of language and the world.

Q: How can explainability be achieved in AI models?

Explainability in AI models can be achieved through various methods, including probing, attribution, and active manipulation. Probing involves training supervised classifiers on internal representations to understand hidden dynamics. Attribution methods assign importance to different parts of input and output representations, providing insights into the model's behavior. Active manipulation involves modifying internal states to better understand and characterize model representations.
