Retrieval Threshold Tuner
Slide the similarity threshold across a scored corpus and trace the F1 curve.
Recall at 90% — what does the precision cost?

Blue bar = your threshold · green = best F1 (0.70).
- Precision
- 70.0%7 kept-relevant of 10 kept
- Recall
- 87.5%7 of 8 relevant found
- F1
- 0.778
- Verdict
- Near the best trade
Method
- Recomputes precision, recall, and F1 at each threshold from a baked scored list with true labels, and precomputes the F1 curve.
- High threshold buys precision and pays recall; the green bar marks the empirical best trade on this corpus.
