## ⚖️ Weight Analysis: {selected_layer}
### 📊 Core Statistics
- **Shape:** {weights.shape}
- **Parameters:** {weights.size:,}
- **Mean:** {np.mean(weights):+.6f}
- **Std:** {np.std(weights):.6f}
### 🔬 Weight Health Analysis
- **L1 Norm:** {l1_norm:.3f} (Manhattan distance - sparsity indicator)
- **L2 Norm:** {l2_norm:.3f} (Euclidean distance - magnitude measure)
- **Dead Weights:** {dead_ratio:.1f}% (weights ≈ 0)
- **Range:** {weight_range:.6f} (Max - Min weight values)
### 🕸️ Sparsity Analysis (8B LLM Research-Based Thresholds)
- **Tiny (<0.001):** {sparse_001:.1f}% {'🟢 Excellent' if sparse_001 < 25 else '🟡 Good' if sparse_001 < 40 else '⚠️ Watch' if sparse_001 < 55 else '🔴 Concerning'}
- **Very Small (<0.01):** {sparse_01:.1f}% {'🟢 Excellent' if sparse_01 < 50 else '🟡 Good' if sparse_01 < 65 else '⚠️ Acceptable' if sparse_01 < 80 else '🔴 High'}
- **Small (<0.1):** {sparse_1:.1f}% {'🟢 Excellent' if sparse_1 < 75 else '🟡 Good' if sparse_1 < 85 else '⚠️ Normal' if sparse_1 < 92 else '🔴 Very High'}
### 📈 Distribution Characteristics
- **25th Percentile:** {p25:.6f}
- **Median:** {p50:.6f}
- **75th Percentile:** {p75:.6f}
- **95th Percentile:** {p95:.6f}
### 🏥 Layer Health Assessment: {health_color} {health_status} ({health_score}/100)
**Key Insights (8B LLM Standards):**
- **Weight Activity:** {100-dead_ratio:.1f}% of weights are active (target: >95%)
- **Sparsity Pattern:** {sparse_1:.1f}% small weights (8B LLMs: 70-85% is normal)
- **Distribution Health:** L2/L1 ratio = {l2_norm/l1_norm:.3f} (balanced ≈ 0.1-1.0)
- **Learning Capacity:** Weight range suggests {'good' if 0.01 < weight_range < 5 else 'limited'} learning capacity
💡 **Research Note:** High sparsity (70-90%) is **normal** for large transformers and indicates efficient learned representations, not poor health.

## 🐠 Goldfish Loss Analysis
**Concept:** Like a goldfish's short memory, randomly drop tokens from loss computation to prevent memorization.

### 🔬 Key Insights:
- **Higher k** → More tokens dropped → Less memorization → Higher loss
- **Lower memorization score** = Better generalization
- **Optimal k**: Usually 0.1-0.2 (10-20% dropout) for LLMs
