## Line Chart: Qwen2.5-14B-Instruct-1M
### Overview
The chart compares the **Average Accuracy** of five methods across varying **Compression Rates** (1x, 2x, 4x, 8x). The y-axis ranges from 0 to 100, while the x-axis represents compression multipliers. A dashed black line (Baseline) serves as a reference, with other methods plotted as solid lines with distinct markers.

### Detailed Analysis
1. **Baseline** (dashed black line):
- Maintains **~95–100% accuracy** across all compression rates.
- No visible decline, indicating robustness to compression.
2. **Minicache** (teal squares):
- **1x**: ~90% accuracy.
- **2x**: ~30% accuracy (sharp drop).
- **4x**: ~25% accuracy.
- **8x**: ~30% accuracy.
- **Trend**: Steep decline after 1x, with partial recovery at 8x.
3. **Single SVD** (teal diamonds):
- **1x**: ~95% accuracy.
- **2x**: ~90% accuracy.
- **4x**: ~85% accuracy.
- **8x**: ~30% accuracy.
- **Trend**: Gradual decline until 8x, where accuracy plummets.
4. **xKV-2 (Ours)** (yellow circles):
- **1x**: ~95% accuracy.
- **2x**: ~93% accuracy.
- **4x**: ~90% accuracy.
- **8x**: ~80% accuracy.
- **Trend**: Slight decline, maintaining higher accuracy than Minicache and Single SVD.
5. **xKV-4 (Ours)** (red circles):
- **1x**: ~95% accuracy.
- **2x**: ~92% accuracy.
- **4x**: ~88% accuracy.
- **8x**: ~85% accuracy.
- **Trend**: Steeper decline than xKV-2 but still outperforms Minicache and Single SVD.

### Key Observations
- **Baseline** is the most stable, with no accuracy loss.
- **Minicache** and **Single SVD** show severe accuracy degradation at higher compression rates.
- **xKV-2** and **xKV-4** (labeled "Ours") balance compression and accuracy better than Minicache and Single SVD but lag behind the Baseline.
- **xKV-4** has a steeper decline than **xKV-2**, suggesting trade-offs in compression efficiency.

### Interpretation
The data demonstrates that **compression rate directly impacts accuracy** for all methods except the Baseline. The **xKV methods** (xKV-2 and xKV-4) appear to be optimized for scenarios requiring moderate compression while preserving higher accuracy compared to Minicache and Single SVD. However, their performance degrades more sharply than the Baseline, indicating a trade-off between compression efficiency and accuracy. The Baseline’s stability suggests it is ideal for applications where compression is not a constraint, while xKV methods may suit use cases prioritizing efficiency over near-perfect accuracy.
