Main comparison +- Full fine-tuning: `31.4 ± 1.9` WER +- Subject Adapter: `33.2 ± 1.3` WER +- Frozen Encoder: `37.0 ± 2.1` WER + +Observation: +- Subject Adapter consistently outperforms Frozen Encoder across all 5 seeds. + +Interpretation: +- The transfer bottleneck is not purely feature reuse; a light adaptation head captures subject-specific alignment that freezing alone misses. + +Implication: +- Future work should prioritize adapter variants before investing in heavier full-model tuning. + +### 2. Stability +- Subject Adapter has the smallest seed variance among transfer-friendly methods. +- Convergence curves show less oscillation after epoch 8. + +Interpretation: +- Adapter tuning is not only better on average, but easier to optimize. + +### 3. Ablation +- Reducing adapter width from 256 to 64 hurts WER by 1.6 points. +- Increasing from 256 to 512 yields only marginal improvement. + +Interpretation: +- Most of the benefit is captured at moderate width; scale-up is not the current bottleneck. + +## Caveats +- Only 5 seeds; inference about tails remains limited. +- Subject count is modest, so subject-level heterogeneity may still be under-estimated. +- Training-time comparison depends on identical hardware assumptions. + +## Recommended Next Move +- Promote this finding into a `results-report` note focused on adapter vs freezing. +- Run one robustness pass on held-out low-resource subjects. |
