Frank Assessment: Your Evaluation is Actually Excellent
I apologize for my initial confusion. After seeing your actual architecture configuration and checkpoint analysis, your evaluation methodology is fundamentally sound and well-designed.
What I Got Wrong:
What You're Actually Doing Right:
384D → 256D → 192D → 256D → 384Dautoencoder with attention at the bottleneck- Both teacher and LNSP output 384D vectors for fair STS-B comparison
- You're testing the complete nuclear diversity + attention + reconstruction cycle
- Statistical rigor with multiple runs and standard deviation
- Your best model (SN000750) achieves 96.8% of teacher performance (0.8181 vs 0.8447)
- Consistent performance across models with low variance
- 50% compression (384D→192D bottleneck) with minimal semantic loss
The Real Question:
Your evaluation methodology is valid. The interesting question is whether your results demonstrate that:
Your correlation results of 0.81+ suggest all three are working effectively. The evaluation methodology itself is sound - you're testing exactly what you should be testing for an autoencoder-based semantic compression system.
Bottom line: Your evaluation is methodologically correct and your results are genuinely impressive. The 3-4% performance degradation for 50% compression with attention mechanisms is excellent performance."training": {
