AI Engineering Bridge Review

Complete this diagnostic before Module 1. It does not reduce the required path.

Closed-book gate​

Explain train/validation/test separation, conditional probability, vector dot products, gradient descent, API boundaries, queues, database indexes, authentication versus authorization, and SLOs. Then:

  1. implement a deterministic baseline and one metric test;
  2. trace a record through ingestion, storage, and an API;
  3. threat-model a service with one external dependency;
  4. package a reproducible command in a locked environment.

Routing​

  • Weak probability or linear algebra: revisit Semester 1.
  • Weak algorithms and measurement: revisit Semester 2.
  • Weak data lineage or distributed systems: revisit Semester 6.
  • Weak security, delivery, or observability: revisit Semesters 5 and 9.

Submit the diagnostic, gaps, remediation evidence, and a signed readiness decision.
