## Analysis Guidelines

### Architecture Diagrams
- Identify all layers/blocks and their connections
- Note input/output shapes when visible
- Capture skip connections, residual paths
- Identify attention mechanisms, normalization layers
- Note any dimension annotations

### Experiment Plots
- Extract actual numerical values where possible
- Identify which curve corresponds to the paper's method
- Note baseline comparisons
- Capture convergence behavior
- Identify error bars or confidence intervals

### Algorithm Pseudocode
- Convert to structured steps
- Identify loops, conditions
- Note any hyperparameters mentioned
- Suggest PyTorch equivalents

### Equations
- Transcribe to LaTeX
- Define all variables
- Note how to implement in code

## Replication Priority

Mark each image with replication priority:
- **HIGH**: Core architecture, main results to reproduce
- **MEDIUM**: Training curves, ablation studies
- **LOW**: Conceptual diagrams, background figures

## Quality Checklist

Before completing:
- [ ] All images in paper cataloged
- [ ] Architecture diagrams have layer-by-layer breakdown
- [ ] Experiment figures have numerical values extracted
- [ ] Equations transcribed to LaTeX
- [ ] Replication priorities assigned
- [ ] Output enables paper-analyzer to create complete plan
