🔬 Calibration Dataset: Deep Dive
REAP's effectiveness depends critically on calibration data that represents the target use case. We specifically optimized for code generation, function/tool calling, and agentic workflows.
Why These 3 Datasets?
Table with columns: Dataset, Samples, Purpose, Why It Matters| Dataset | Samples | Purpose | Why It Matters |
|---|
| evol-codealpaca-v1 | 700 | Code generation | 51% of mix — Code tasks activate specific expert pathways; pruning without code calibration destroys coding ability |
| xlam-function-calling-60k | 330 | Function/tool calling | 24% of mix — Tool use requires structured JSON output; experts handling schema generation must be preserved |
| SWE-smith-trajectories |
The Science Behind Dataset Selection
REAP Algorithm:
1. Forward pass calibration samples through model
2. Record which experts activate and their magnitudes
3. Compute saliency = router_weight × activation_norm
4. Prune lowest-saliency experts
Key Insight: Experts are TASK-SPECIFIC
├── Some experts specialize in natural language
├── Some experts specialize in code syntax
├── Some experts specialize in JSON/structured output
└── Some experts specialize in multi-turn context
If calibration lacks code → code-specialized experts appear "unused" → get pruned → model loses coding ability
Cerebras' Original Mix (from paper)
Cerebras used the same 3 datasets in their GLM-4.6 REAP experiments:
- evol-codealpaca-v1 for code generation
- xlam-function-calling-60k for tool calling
- SWE-smith-trajectories for agentic tasks
We followed this exact recipe for reproducibility.
