# Technical Document Extraction: HotPotQA Episodic Memory Graph
## Chart Title
- **(c) HotPotQA Episodic Memory**
## Axes
- **Y-Axis**:
- Label: `Proportion of Solved Tasks`
- Scale: `0.5` to `1.0` (increments of `0.1`)
- **X-Axis**:
- Label: `Trial Number`
- Scale: `0` to `4` (integer steps)
## Legend
- **Labels & Colors**:
1. `CoT (GT) only` → Gray dashed line
2. `CoT (GT) EPM` → Pink dashed line
3. `CoT (GT) EPM + Reflexion` → Purple solid line
## Data Trends
### Line 1: `CoT (GT) only` (Gray Dashed)
- **Values**:
- Trial 0: `~0.61`
- Trial 1: `~0.61`
- Trial 2: `~0.61`
- Trial 3: `~0.61`
- Trial 4: `~0.61`
- **Trend**: Flat line, no significant change across trials.
### Line 2: `CoT (GT) EPM` (Pink Dashed)
- **Values**:
- Trial 0: `~0.62`
- Trial 1: `~0.65`
- Trial 2: `~0.65`
- Trial 3: `~0.65`
- Trial 4: `~0.65`
- **Trend**: Initial increase from Trial 0 to 1, then plateaus.
### Line 3: `CoT (GT) EPM + Reflexion` (Purple Solid)
- **Values**:
- Trial 0: `~0.62`
- Trial 1: `~0.70`
- Trial 2: `~0.72`
- Trial 3: `~0.74`
- Trial 4: `~0.74`
- **Trend**: Steady upward trajectory until Trial 3, then plateaus.
## Key Observations
1. **Performance Comparison**:
- `CoT (GT) EPM + Reflexion` consistently outperforms other methods, reaching `~0.74` by Trial 3.
- `CoT (GT) EPM` shows moderate improvement but plateaus earlier than the Reflexion-enhanced version.
- `CoT (GT) only` remains static at `~0.61`, indicating no learning over trials.
2. **Learning Dynamics**:
- Reflexion integration (`EPM + Reflexion`) enables progressive improvement, suggesting enhanced episodic memory retention.
- EPM alone provides limited gains compared to the Reflexion-augmented approach.
## Structural Notes
- No embedded data tables or additional textual annotations present.
- All lines originate from Trial 0 and terminate at Trial 4, with no mid-trial discontinuities.
- Legend labels are unambiguously mapped to line styles/colors.
