Peter Norvig: We Are Seduced by Our Low-Dimensional Metaphors | AI Podcast Clips
4 segments available
This is a clip from a conversation with Peter Norvig from Sep 2019. New full episodes every Mon & Thu and 1-2 new clips or a new non-podcast video on all other days. You can watch the full conversation here: https://www.youtube.com/watch?v=_VPxEcT_Adc (more links below) Podcast full episodes playlist: https://www.youtube.com/playlist?list=PLrAXtmErZgOdP_8GztsuKi9nrraNbKKp4 Podcasts clips playlist: https://www.youtube.com/playlist?list=PLrAXtmErZgOeciFP3CBCIEElOJeitOr41 Podcast website: https://lexfridman.com/ai Podcast on iTunes: https://apple.co/2lwqZIr Podcast on Spotify: https://spoti.fi/2nEwCF8 Podcast RSS: https://lexfridman.com/category/ai/feed/ Note: I select clips with insights from these much longer conversation with the hope of helping make these ideas more accessible and discoverable. Ultimately, this podcast is a small side hobby for me with the goal of sharing and discussing ideas. For now, I post a few clips every Tue & Fri. I did a poll and 92% of people either liked or loved the posting of daily clips, 2% were indifferent, and 6% hated it, some suggesting that I post them on a separate YouTube channel. I hear the 6% and partially agree, so am torn about the whole thing. I tried creating a separate clips channel but the YouTube algorithm makes it very difficult for that channel to grow unless the main channel is already very popular. So for a little while, I'll keep posting clips on the main channel. I ask for your patience and to see these clips as supporting the dissemination of knowledge contained in nuanced discussion. If you enjoy it, consider subscribing, sharing, and commenting. Peter Norvig is a research director at Google and the co-author with Stuart Russell of the book Artificial Intelligence: A Modern Approach that educated and inspired a whole generation of researchers including myself to get into the field.

Segments Timeline
Trust and Explainability in AI
Peter Norvig discusses the importance of trust, validation, and verification in AI systems. He emphasizes that explanations alone are insufficient; we need to understand the underlying reasons for AI decisions, especially in critical situations like loan approvals. Norvig highlights the necessity of having a conversation around these explanations to ensure accountability and transparency.
"anytime use noodle networks anytime you learn from data form representation from day in an automated way it's not very explainable as to or it's not introspective to us humans in terms of how this neu..."
The Complexity of AI Decisions
In this segment, Norvig explores the complexity of AI decision-making processes. He argues that relying solely on explanations can be misleading, as they may not reflect the true reasons behind decisions. He advocates for a broader understanding of AI models and the need for adversarial testing to uncover potential biases and vulnerabilities in AI systems.
"them and we want to understand where they work and where they don't work and in an explanation can be part of that right so I apply for loan and I get denied I want some explanation of why and you hav..."
Seduced by Low-Dimensional Metaphors
Peter Norvig critiques the simplistic metaphors often used to describe AI, such as low-dimensional spaces. He argues that these metaphors can lead to misconceptions about AI capabilities and limitations. Instead, he suggests viewing AI as operating in a complex, high-dimensional space, which requires a deeper understanding of its behavior and potential pitfalls.
"the pattern that's right so you want to have that kind of capability you want to have these adversarial testing right so we thought we're doing pretty good at object recognition in images we said look..."
Building Trust in AI Systems
Norvig reflects on the societal challenge of building trust in AI systems compared to human interactions. He notes that humans often trust each other quickly, while AI systems face skepticism. He emphasizes the importance of communication technology in fostering trust and making informed decisions, suggesting that the evolution of AI is intertwined with advancements in communication.
"now we've got to deal with that so it wasn't so much an explanation but it was an understanding of what the models are and what they're doing and now we can start exploring how do you fix that yeah va..."
