And what usually gets you stuck isn't the AI—it's permissions, publishers, and the library. paper-fetch uses a step-by-step route from open access, to official publisher APIs, to your own hospital library to turn a DOI into a full-text PDF, without taking any piracy routes.https://drpwchen.com/en/posts/my-data-my-benchmark/Mon, 13 Jul 2026 16:31:00 +0800https://drpwchen.com/en/posts/my-data-my-benchmark/MediaTek's official benchmark already proves Breeze-ASR-25 beats Whisper, but it isn't testing your task. Using a 180,000-word glossary built from hundreds of textbooks as a yardstick, I found it captures 49% more real vocabulary and runs faster. Another finding not in any model card: the time alignment of the Taiwanese version, Breeze-ASR-26, has regressed. Default decoding only segments once every 30 seconds, which outright breaks when making subtitles or aligning with slides, but enabling word-level timestamps saves it. The testing method is open-sourced.https://drpwchen.com/en/posts/vault-graph-rag/Mon, 22 Jun 2026 15:00:00 +0800https://drpwchen.com/en/posts/vault-graph-rag/I threw a new paper on SQL-RAG at Claude to verify it myself: useless for a redundant textbook library, but a great fit for finding "related notes" in a sparse Obsidian medical note vault. After swapping the ranking to personalized PageRank, the proportion of correctly finding related notes jumped from 34% to 84%, and I put it straight into production.
