Step 4: Evaluation Metrics #### Standard Metrics (Always Report) | Metric | What It Measures | Tool | |--------|-----------------|------| | PSNR (dB) | Pixel-level fidelity | Standard | | SSIM | Structural similarity | Standard | | LPIPS | Perceptual similarity | lpips Python package | #### Supplementary Metrics (Report When Relevant) | Metric | When to Use | Note | |--------|------------|------| | FPS | Any real-time claim | Report with GPU spec | | VRAM (GB) | Memory efficiency claim | Peak during training/inference | | #Gaussians (M) | Compression/scalability | Model size | | Model Size (MB) | Compression methods | Storage efficiency | | FID/KID | Generative methods | Distribution quality | | Chamfer Distance | Geometry reconstruction | Surface accuracy | | Normal Consistency | Surface reconstruction | Normal map quality | | CHF (Cutting-Hole Frequency) | High-frequency modeling | Boundary sharpness | ### Step 5: Ablation Study Design #### Standard Ablation Matrix ``` | Configuration | Component A | Component B | Component C | Loss A | PSNR↑ | SSIM↑ | LPIPS↓ | |---------------|-------------|-------------|-------------|--------|-------|-------|--------| | 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 | | Training strategy | Disable adaptive density / change schedule | Shows strategy importance | | Architecture change | Remove specific module | Isolates module contribution | ### Step 6: Visualization Plan #### Must-Have Figures | Figure | Content | Purpose | |--------|---------|---------| | Figure 1 | Motivation / Teaser | Hook the reader | | Figure 2 | Method overview / Architecture | Explain the approach | | Figure 3 | Qualitative comparison | Visual proof of quality | | Figure 4 | Ablation visualization | Show component effects visually | | Figure 5 | Failure cases (optional) | Shows honesty | #### Recommended Visual Comparisons - Novel view rendering comparison (multi-method, multi-scene grid) - Zoom-in comparison for fine details / boundaries - Depth map or normal map visualization - Gaussian point cloud visualization - Training convergence curves ### Step 7: Efficiency Analysis When making efficiency claims, include: | Aspect | Measurement | Report Format | |--------|------------|---------------| | Training time | Wall-clock hours per scene | "X hours on 1x RTX 4090" | | Rendering speed | FPS at resolution Y | "XX FPS at 1080p" | | Peak VRAM | GB during training/inference | "X GB peak" | | Model storage | MB per scene | "X MB" | | Scaling behavior | Time vs #images / resolution | Plot or table | **Always report GPU model** — reviewers compare across papers. ## Output Format Generate a complete experiment plan: ``` ## Experiment Plan for [Method Name] ### 1. Datasets | Priority | Dataset | Scenes | Reason | |----------|---------|--------|--------| | Must | ... | ... | ... | ### 2. Baselines | Priority | Method | Venue | Category | |----------|--------|-------|----------| | Must | ... | ... | ... | ### 3. Metrics | Must Report | Optional | |-------------|----------| | PSNR, SSIM, LPIPS | FPS, VRAM, ... | ### 4.

Figure Plan | Figure | Content | Target Page | |--------|---------|-------------| | Fig 1 | ... | 1 | ### 6. Efficiency Analysis - Training: ... - Rendering: ... - Memory: ... ### 7. Anticipated Reviewer Concerns & Preemptive Responses | Concern | Response Strategy | |---------|------------------| | "Why not compare with X?" | ... | ``` ## Rules 1. **Be practical**: Consider the actual computational budget. Don't suggest 100 scenes if the author has 1 GPU. 2. **Be realistic**: Don't claim "state-of-the-art" unless metrics clearly support it. 3. **Be thorough**: It's better to over-prepare than to receive "insufficient experiments" reviews. 4. **Venue-aware**: CVPR allows 8 pages + references.
