 ### Why Hyperparameter Optimization Instead of Fine-tuning
 
-Due to **hardware limitations** (no dedicated GPU, CPU-only execution), the project pivoted from fine-tuning to hyperparameter optimization:
-- Fine-tuning deep learning models without GPU is prohibitively slow
-- Inference time is ~69 seconds/page on CPU
-- Hyperparameter optimization proved to be an effective alternative, achieving 80.9% CER reduction
+The project chose **hyperparameter optimization** over fine-tuning because:
+- Fine-tuning requires extensive labeled datasets specific to the domain
+- Hyperparameter tuning can improve pretrained models without retraining
+- GPU acceleration (RTX 3060) enables efficient exploration of hyperparameter space

 | Model | CER | Character Accuracy |
 |-------|-----|-------------------|
-| PaddleOCR Baseline | 7.78% | 92.22% |
-| PaddleOCR-HyperAdjust | **1.49%** | **98.51%** |
+| PaddleOCR Baseline | 8.85% | 91.15% |
+| PaddleOCR-HyperAdjust (full dataset) | **7.72%** | **92.28%** |
+| PaddleOCR-HyperAdjust (best trial) | **0.79%** | **99.21%** |
 
-**Goal achieved:** CER < 2% (target was < 2%, result is 1.49%)
+**Goal status:** CER < 2% achieved in best trial (0.79%). Full dataset shows 12.8% improvement.

 ```python
 config_optimizada = {
-    "textline_orientation": True,           # CRITICAL - reduces CER ~70%
-    "use_doc_orientation_classify": False,
+    "textline_orientation": True,           # CRITICAL for complex layouts
+    "use_doc_orientation_classify": True,   # Improves document orientation

 }
 ```
 
 ### Key Findings
 
-1. `textline_orientation=True` is the most impactful parameter (reduces CER by 69.7%)
-2. `text_det_thresh` has -0.52 correlation with CER; values < 0.1 cause catastrophic failures
-3. Document correction modules (`use_doc_orientation_classify`, `use_doc_unwarping`) are unnecessary for digital PDFs
+1. `textline_orientation=True` is critical for documents with mixed layouts
+2. `use_doc_orientation_classify=True` improves document orientation detection in GPU config
+3. `text_det_thresh` has -0.52 correlation with CER; values < 0.01 cause catastrophic failures
+4. `use_doc_unwarping=False` is optimal for digital PDFs (unnecessary processing)

 ### Priority Tasks
 1. **Validate on other document types** - Test optimal config on invoices, forms, contracts
-2. **Expand dataset** - Current dataset has only 24 pages
+2. **Use larger tuning subset** - Current 5 pages caused overfitting; recommend 15-20 pages
 3. **Create presentation slides** - For thesis defense
 4. **Final document review** - Open in Word, update indices (Ctrl+A, F9), verify formatting
 
 ### Optional Extensions
 - Explore `text_det_unclip_ratio` parameter (was fixed at 0.0)
-- Compare with actual fine-tuning (if GPU access obtained)
+- Compare with actual fine-tuning
 - Multi-objective optimization (CER + WER + inference time)
