#74 Dr. ANDREW LAMPINEN - Symbolic behaviour in AI [UNPLUGGED]

Apr 14, 2022
Dr. Andrew Lampinen, a Senior Research Scientist at DeepMind with a PhD from Stanford, dives into the nuanced world of symbolic behavior in AI. He discusses how machines struggle to replicate human symbol use and emphasizes that meanings are shaped by user agreements rather than symbol content. Lampinen critiques traditional intelligence notions, advocating for a meaning-first approach in AI. The conversation also touches on the complexity of subjectivity, the limits of formal logic, and the ethical challenges in aligning AI with human values.

INSIGHT

Symbolic Behavior's Core Idea

  • Humans use symbols, but machines haven't replicated this ability yet.
  • Symbol meaning is established by users' agreement and behaviors, not just content.
INSIGHT

The Triadic Relationship of Meaning

  • Symbols derive meaning from how they're used, not just their content, similar to collaborative filtering.
  • Infer meaning from symbol affinity and user engagement rather than the symbol's inherent properties.

Semantics over Syntax

  • Syntax in itself isn't important; it's only useful for understanding semantics.
  • Humans' grasp of semantic mapping gives them power beyond syntactic manipulation.
