## Chart: Mistral-7B-v0.1 vs Mistral-7B-v0.3 I-Don't-Know Rate
### Overview
The image presents two line charts comparing the "I-Don't-Know Rate" of two versions of the Mistral-7B model (v0.1 and v0.3) across different layers (1 to 32) and question-answering datasets. The charts show how the model's uncertainty varies with layer depth for both question-anchored and answer-anchored approaches on four datasets: PopQA, TriviaQA, HotpotQA, and NQ.

### Detailed Analysis
**Mistral-7B-v0.1 (Left Chart):**
* **Q-Anchored (PopQA) (Blue solid line):** Starts at 100, drops sharply to around 10 at layer 5, rises to 100 at layer 10, then fluctuates between 20 and 60 for the remaining layers.
* **A-Anchored (PopQA) (Tan dashed line):** Starts at approximately 60, decreases to 40 at layer 5, then increases to 60 at layer 10, and fluctuates between 50 and 70 for the remaining layers.
* **Q-Anchored (TriviaQA) (Green dotted line):** Starts at 60, drops to 10 at layer 10, then fluctuates between 10 and 30 for the remaining layers.
* **A-Anchored (TriviaQA) (Tan dotted-dashed line):** Starts at 50, drops to 20 at layer 5, then fluctuates between 20 and 40 for the remaining layers.
* **Q-Anchored (HotpotQA) (Red dashed line):** Starts at 100, drops to 60 at layer 5, then fluctuates between 60 and 90 for the remaining layers.
* **A-Anchored (HotpotQA) (Tan solid line):** Starts at 50, increases to 60 at layer 5, then fluctuates between 50 and 70 for the remaining layers.
* **Q-Anchored (NQ) (Purple dotted line):** Starts at 100, drops to 20 at layer 5, then fluctuates between 20 and 40 for the remaining layers.
* **A-Anchored (NQ) (Tan dotted line):** Starts at 60, drops to 20 at layer 5, then fluctuates between 20 and 40 for the remaining layers.
**Mistral-7B-v0.3 (Right Chart):**
* **Q-Anchored (PopQA) (Blue solid line):** Starts at 100, drops sharply to around 10 at layer 5, rises to 60 at layer 10, then fluctuates between 10 and 60 for the remaining layers.
* **A-Anchored (PopQA) (Tan dashed line):** Starts at approximately 60, decreases to 50 at layer 5, then increases to 70 at layer 10, and fluctuates between 60 and 80 for the remaining layers.
* **Q-Anchored (TriviaQA) (Green dotted line):** Starts at 60, drops to 20 at layer 10, then fluctuates between 20 and 40 for the remaining layers.
* **A-Anchored (TriviaQA) (Tan dotted-dashed line):** Starts at 60, drops to 30 at layer 5, then fluctuates between 30 and 50 for the remaining layers.
* **Q-Anchored (HotpotQA) (Red dashed line):** Starts at 100, drops to 70 at layer 5, then fluctuates between 70 and 90 for the remaining layers.
* **A-Anchored (HotpotQA) (Tan solid line):** Starts at 60, increases to 70 at layer 5, then fluctuates between 60 and 80 for the remaining layers.
* **Q-Anchored (NQ) (Purple dotted line):** Starts at 100, drops to 30 at layer 5, then fluctuates between 30 and 50 for the remaining layers.
* **A-Anchored (NQ) (Tan dotted line):** Starts at 60, drops to 30 at layer 5, then fluctuates between 30 and 50 for the remaining layers.
### Key Observations
* Both versions of the model show a similar trend: the "I-Don't-Know Rate" generally decreases in the initial layers (1-5) and then fluctuates for the remaining layers.
* The Q-Anchored (PopQA) line shows a significant drop in the "I-Don't-Know Rate" in the initial layers for both versions.
* The Q-Anchored (HotpotQA) line consistently shows a high "I-Don't-Know Rate" across all layers for both versions.
* The A-Anchored lines generally have a lower "I-Don't-Know Rate" compared to the Q-Anchored lines for the same dataset.
* The shaded regions around each line indicate the uncertainty or variance in the "I-Don't-Know Rate" for each dataset and anchoring method.
### Interpretation
The charts suggest that the Mistral-7B model's uncertainty varies depending on the dataset and whether the question or answer is used as the anchor. The initial layers seem to play a crucial role in reducing the model's uncertainty, as indicated by the sharp drop in the "I-Don't-Know Rate" for some datasets. The HotpotQA dataset consistently results in higher uncertainty, suggesting that it may be more challenging for the model. The differences between the Q-Anchored and A-Anchored lines indicate that the model's uncertainty is also influenced by the anchoring method. Comparing v0.1 and v0.3, there are subtle differences in the "I-Don't-Know Rate" for some datasets, but the overall trends remain similar. This suggests that the changes between the two versions did not significantly impact the model's uncertainty.
