Section: module-2-vector-search (This topic fits under Module 2: Vector Search, addressing numerical precision and cross-implementation comparisons that students might encounter when evaluating vector search results.)
Related Issue: #276
Question
Why can np.allclose(scores, scores_loop) return False when comparing the matrix multiplication version of vector search with a Python for loop? Aren't they doing the same math?
Decision Rationale
The proposed question targets a practical floating-point precision nuance in Module 2 vector search that is not covered by existing FAQs. It explains why two mathematically equivalent approaches can yield slightly different results and how to robustly compare them, warranting a new FAQ entry.
