Pattern of the week
Unsupervised Learning for Agents
- What:
- Learns patterns from unlabeled data via embeddings, clustering, or anomaly detection, then validates findings with domain experts.
- When to use it:
- You have raw data without labels and need to discover structure, segment users, or flag unusual cases before applying supervised methods.
- Watch out:
- Clusters and anomaly scores are unstable artifacts; validation often reveals they don't match real business categories or decision boundaries.
