This commit introduces the `doctate-canary` service and associated sweep
experiments.
The service provides access to the `nvidia/canary-1b-v2` ASR model via a
native FastAPI API. It includes deployment scripts, Docker
configurations, and detailed documentation on installation, API usage,
and environment variables.
The sweep experiments aim to thoroughly evaluate the Canary model's
performance under various configurations. This includes testing
different inference pipelines (single-shot vs. buffered), decoding
strategies (greedy vs. beam search), and parameter tuning (chunk length,
overlap, batch size, precision). The goal is to reproduce previous
findings and identify optimal settings.
The commit also includes:
- Utility scripts for audio transcoding and manipulation.
- Comprehensive logging and result collection mechanisms for the sweep
runs.
- Detailed analysis of `dur=0` occurrences and word confidence,
concluding they are not reliable indicators of hallucination.
- Documentation on the interaction between decoding parameters,
especially `return_hypotheses`, and the availability of confidence
scores.
Nested Cargo-Workspace unter experiments/ als Pfad-Dependency auf
../server. Reproduziert die Production-Pipeline 1:1 durch direkte
Wiederverwendung der Server-Module (transcribe::whisper, analyze::llm,
gazetteer, ffmpeg-Remux) — kein eigenes HTTP-Re-Implementieren, kein
Drift-Risiko zur Live-Pipeline.
Drei bin-Targets:
- run_full_case: volle Pipeline (ffmpeg → whisper → pre-gazetteer → llm
→ post-gazetteer), n Runs einer Variante
- run_llm_only: schneller LLM-Iterations-Pfad auf existierenden,
gazetteer-bereinigten Transkripten — spart Whisper-Calls
- diff_runs: qualitativer Vergleich zwischen zwei Run-Verzeichnissen
Repo-Hygiene: case_*/ (Patientendaten, Symlinks zu tmpdata) und _data/
(Run-Outputs) sind komplett gitignored. Nur Code und fall-übergreifende
Prompt-Hypothesen (prompts/) werden versioniert.
Erste Prompt-Varianten zur Treue-Klausel und Konflikt-Auflösung:
prompts/llm/v1_treue.txt, v2_treue.txt.
