## Bar Chart: Refusal Ratio by Training Set and Hallucination Type
### Overview
The chart compares refusal ratios (%) across three hallucination types (Factual Asso., Asso. Hallu., Unasso. Halluc.) for two training sets (UH Only, AH Only). Refusal ratios are visualized as grouped bars with distinct colors.
### Components/Axes
- **X-axis (Training Set)**: Two categories - "UH Only" (left) and "AH Only" (right).
- **Y-axis (Refusal Ratio %)**: Scaled from 0 to 100 in 20% increments.
- **Legend**: Located in the top-right corner, mapping colors to hallucination types:
- Green: Factual Asso.
- Blue: Asso. Hallu.
- Red: Unasso. Halluc.
### Detailed Analysis
1. **UH Only Training Set**:
- **Unasso. Halluc. (Red)**: ~85% refusal ratio (tallest bar).
- **Asso. Hallu. (Blue)**: ~15% refusal ratio.
- **Factual Asso. (Green)**: ~10% refusal ratio.
2. **AH Only Training Set**:
- **Unasso. Halluc. (Red)**: ~50% refusal ratio.
- **Asso. Hallu. (Blue)**: ~20% refusal ratio.
- **Factual Asso. (Green)**: ~15% refusal ratio.
### Key Observations
- **Dominance of Unasso. Halluc.**: Red bars (Unasso. Halluc.) consistently show the highest refusal ratios in both training sets.
- **Training Set Impact**:
- UH Only achieves ~85% refusal for Unasso. Halluc., while AH Only drops to ~50%.
- Factual Asso. refusal ratios are lowest across all categories (~10-15%).
- **Color Consistency**: Legend colors match bar colors exactly (green=green, blue=blue, red=red).
### Interpretation
The data suggests that training models exclusively on unassociated hallucinations (UH Only) significantly improves their ability to refuse unassociated hallucinations compared to training on associated hallucinations (AH Only). However, both training approaches struggle with factual associations, indicating a potential gap in handling contextually accurate but non-hallucinatory outputs. The stark contrast between UH and AH training for Unasso. Halluc. refusal (~85% vs. ~50%) highlights the importance of targeted training data composition in mitigating specific hallucination types.
