Problem

Scenario

You trained a transformer model after starting with a simpler NLP baseline, and the transformer performed better on the same task. Now you need to explain that improvement in a way that is technically sound, not just descriptive.

Question

How would you explain why a transformer improved your baseline model?

What This Tests

Understanding of transformer advantages over lexical baselines
Ability to compare fine-tuned models on the same task
Use of F1 and per-class analysis rather than accuracy alone
Evidence-based explanation through error analysis
