AXRP - the AI X-risk Research Podcast
38.3 - Erik Jenner on Learned Look-Ahead
Dec 12, 2024
Erik Jenner, a third-year PhD student at UC Berkeley's Center for Human Compatible AI, dives into the fascinating world of neural networks in chess. He explores how these AI models exhibit learned look-ahead abilities, questioning whether they strategize like humans or rely on clever heuristics. The discussion also covers experiments assessing future planning in decision-making, the impact of activation patching on performance, and the relevance of these findings to AI safety and X-risk. Jenner's insights challenge our understanding of AI behavior in complex games.

Neural Networks and Chess Performance
Neural networks have shown remarkable ability in playing chess, raising questions about the mechanisms behind their performance. Unlike traditional methods that rely heavily on search algorithms and planning, neural networks can make effective moves based on a single forward pass. This performance suggests that they might have an innate capability to represent future moves when deciding their next action, blurring the lines between intuition and explicit search. The exploration of this faculty could lead to a deeper understanding of how artificial intelligence models process and evaluate strategic decisions.
