969: The Laws of Thought: The Math of Minds and Machines, with Prof. Tom Griffiths
Summary
Princeton Professor Tom Griffiths discusses his new book, "The Laws of Thought," which explores the mathematical models underlying both biological and artificial intelligence. He highlights how mathematical principles, traditionally used for the physical world, can also describe cognitive science, or "the internal world." Griffiths' research at Princeton's Computational Cognitive Science Lab and AI Lab focuses on understanding human cognition through computational ideas and enhancing AI with insights from human minds. He notes that while psychologists often view humans as irrational, computer scientists find human intelligence inspiring. The discussion covers the historical shift from symbolic AI to probabilistic and neural approaches, the impact of training data sensitivity on large language models (LLMs), and the critical role of inductive biases in human learning compared to AI's data-intensive methods. The conversation also touches on modeling curiosity in AI and the challenges of evaluating AI systems scientifically.
Key takeaway
For AI scientists and research scientists developing next-generation models, recognize that current LLMs' probabilistic nature makes them prone to outputting more common answers, even for deterministic tasks. Your systems will benefit from incorporating stronger inductive biases, potentially through techniques like meta-learning, to achieve human-like efficiency in learning from limited data and to foster genuinely novel, less probable outputs. This approach can help bridge the significant gap between human and AI learning efficiency.
Key insights
Mathematical principles can describe both external physical laws and internal cognitive processes in biological and artificial intelligence.
Principles
- Human cognition excels at inductive problems, making inferences from incomplete data.
- AI systems' behavior is highly sensitive to their training data and inherent probabilistic nature.
- Inductive biases are crucial for efficient learning, bridging the gap between human and AI data requirements.
Method
Cognitive science methods, including targeted experiments and large-scale online data collection, are used to study both human and AI systems by analyzing behavioral responses to specific problems.
In practice
- Use compositional prompting to explore lower probability outputs from LLMs.
- Consider meta-learning to instill human-like inductive biases in neural networks.
