Use Cases

What ML adds to Nostr apps

  • Timeline ranking
  • Abuse and spam moderation
  • Search via embeddings

Dataset Curation

Quality in, quality out

Sampling

Avoid bias; stratify by kinds, authors, time.

Labeling

Lightweight human-in-the-loop for moderation/quality.

Versioning

Track dataset and feature versions for reproducibility.

Offline Pipeline

ETL, features, training, and evaluation

Export curated events, build features, and train models offline; deploy small on-device models where possible.

Legend: Raw events are curated to features, trained and evaluated offline; approved models are deployed to serve real-time inference with caching.

Integration

Real-time inference and fallbacks

Serve models behind a feature-flag; cache results and provide predictable fallbacks for cold-start.

Evaluation

Measure model value, not just accuracy

Define task metrics (CTR, abuse catch-rate), offline AUC/precision-recall, and run online A/B tests gated by safety checks.
