Why TensorOpt

Statistical rigor

Bootstrap confidence intervals and paired significance tests on every retrieval metric. Eval-tooling vendors publish NDCG, MRR, and Precision@k as features; I apply classical IR statistical discipline on top.

Independent third-party

Not a tooling vendor scoring against its own SaaS. Outside-counsel-style assessment of whichever eval stack and search vendor you already run.

Practitioner-authored

Methodology grounded in Designing Hybrid Search Systems (Leanpub) and the forthcoming Measuring Search. The runbook is the book, productized.
