### π Training Details:
|
| 278 |
-
|
| 279 |
-
**Phase 1: Initial Training (90 epochs)**
|
| 280 |
-
- Optimizer: SGD + Nesterov momentum
|
| 281 |
-
- LR Schedule: OneCycleLR (0.02 β 0.2 β 0.00001)
|
| 282 |
-
- Regularization: Label smoothing, weight decay, dropout
|
| 283 |
-
- Result: 76.75%
|
| 284 |
-
|
| 285 |
-
**Phase 2: Fine-tuning (Multiple LR restarts)**
|
| 286 |
-
- LR=0.001: 76.88% (oscillated)
|
| 287 |
-
- LR=0.0005: **77.09%** β
(best achieved!)
|
| 288 |
-
- LR=0.0003: 77.02% (similar ceiling)
|
| 289 |
-
|
| 290 |
-
**Result:** 77.09% represents the natural ceiling for standard
|
| 291 |
-
from-scratch training. Achieving 78%+ requires advanced augmentation
|
| 292 |
-
techniques (MixUp, CutMix) beyond standard methods.
|
| 293 |
-
|
| 294 |
-
**Key Techniques:**
|
| 295 |
-
- Mixed precision training (torch.amp)
|
| 296 |
-
- Distributed training (8 GPUs, DDP)
|
| 297 |
-
- Robust image loading (handles corrupted files)
|
| 298 |
-
- Advanced augmentation (crop, flip, color jitter, erasing)
|
| 299 |
-
|
| 300 |
-
### π° Cost Analysis:
|
| 301 |
-
- Hardware: AWS p4d.24xlarge (8Γ A100 40GB)
|
| 302 |
-
- Duration: ~13 hours
|
| 303 |
-
- Cost: ~$110 (spot pricing)
|
| 304 |
|
| 305 |
-
### π Performance Context:
|
| 306 |
-
- **Industry Baseline:** 70-75% (we beat by 2-7%)
|
| 307 |
-
- **Good Training:** 75-77% (top tier!)
|
| 308 |
-
- **Our Result:** 77.09% (top 10% of from-scratch)
|
| 309 |
-
- **Research-Level:** 78%+ (requires MixUp/CutMix)
