This research paper examines the impact of an artificial intelligence tool for materials discovery on the productivity and performance of scientists working in a large U.S. firm's R&D lab. The study exploits a randomized rollout of the AI tool across teams of scientists, allowing the researchers to draw causal inferences about the effects of the technology. The paper demonstrates that the AI tool significantly increases the rate of materials discovery, patent filings, and product innovation, but these benefits are unequally distributed among scientists. The researchers find that the AI tool is most beneficial to scientists with strong judgment skills, which involve the ability to evaluate and prioritize AI-generated candidate compounds. The study also reveals that the AI tool automates a significant portion of idea generation tasks, resulting in a reallocation of scientist labor towards judgment tasks. This reallocation, along with the increased demand for judgment skills, explains the heterogeneous impact of the AI tool on scientific performance.

Ep42. The Geometry of Concepts: Sparse Autoencoder Feature Structure
This research paper investigates the structure of the concept universe represented by large language models (LLMs), specifically focusing on how sparse autoencoders (SAEs) can be used to discover and analyze concepts within these models. The authors explore this structure at three distinct scales: the “atomic” scale, where they look for geometric patterns representing semantic relationships between concepts; the “brain” scale, where they identify clusters of features that tend to fire together within a document and are spatially localized; and the "galaxy" scale, where they examine the overall shape and clustering of the feature space. The authors find that the concept universe exhibits a surprising degree of structure, suggesting that SAEs can be a powerful tool for understanding the inner workings of LLMs.
