Structural similarity | Standard | | LPIPS | Perceptual similarity | lpips Python package | #### Supplementary Metrics (Report When Relevant) | Metric | When to Use | Note |

|---------------|-------------|-------------|-------------|--------|-------|-------|--------| | Full Model | ✓ | ✓ | ✓ | ✓ | XX.X | 0.XXX | 0.XXX | | w/o A | ✗ | ✓ | ✓ | ✓ | XX.X | 0.XXX | 0.XXX | | w/o B | ✓ | ✗ | ✓ | ✓ | XX.X | 0.XXX | 0.XXX | | w/o C | ✓ | ✓ | ✗ | ✓ | XX.X | 0.XXX | 0.XXX | | w/o Loss A | ✓ | ✓ | ✓ | ✗ | XX.X | 0.XXX | 0.XXX | | A+B only | ✓ | ✓ | ✗ | ✗ | XX.X | 0.XXX | 0.XXX | ``` #### Ablation Design Principles 1. **One variable at a time**: Each row changes exactly one component 2. **Show interaction effects**: Include rows that combine removal of 2+ components 3. **Use consistent dataset**: Ablations on a single representative dataset are fine 4. **Include running time**: Show the computational cost of each component 5. **Statistical significance**: Run 3 seeds if results are close #### Common Ablation Targets | Component | What to Ablate | Expected Outcome | |-----------|---------------|-----------------| | New loss function | Remove / replace with L1 | Quality drop confirms contribution | | New primitive | Replace with standard Gaussian | Shows primitive advantage | | Regularization term | Remove each term separately | Shows each term's effect | |
