We'll be using my brand new textbook (!) that's meant to make it much easier to define your what you're looking for and implement a pipeline for doing it. myumi.ch/w9nbN https://myumi.ch/w9nbN13 Jul 2026 20:01 +0000at://did:plc:bfmnjv7qui2bdpudo7rbudop/app.bsky.feed.post/3mqkiaysuyk2qhttps://bsky.app/profile/ahalterman.bsky.social/post/3lz6yrl7zp222Very excited that my paper with @katakeith.bsky.social is now out in @polanalysis.bsky.social. We investigate whether LLMs actually follow the instructions/definitions provided in codebooks, propose some diagnostics, and release a new evaluation dataset. https://www.cambridge.org/core/journals/political-analysis/article/codebook-llms-evaluating-llms-as-measurement-tools-for-political-science-concepts/7B323A0E47F782F2698A0AE849EA00DE19 Sep 2025 13:45 +0000at://did:plc:bfmnjv7qui2bdpudo7rbudop/app.bsky.feed.post/3lz6yrl7zp222https://bsky.app/profile/ahalterman.bsky.social/post/3lh2iela4uc2uNew paper in Political Analysis on synthetic text data for training classifiers. Main idea: generate training examples with LLMs, then fit classifiers on synthetic (+real) text. Paper has validations and guidance.
