## Line Chart: I-Don't-Know Rate vs. Layer for Llama-3-8B and Llama-3-70B
### Overview
The image presents two line charts comparing the "I-Don't-Know Rate" across different layers of two language models: Llama-3-8B and Llama-3-70B. Each chart plots the rate for various question-answering datasets (PopQA, TriviaQA, HotpotQA, and NQ) using both question-anchored (Q-Anchored) and answer-anchored (A-Anchored) approaches. The x-axis represents the layer number, and the y-axis represents the I-Don't-Know Rate, ranging from 0 to 100.

### Key Observations
* For both models, the "I-Don't-Know Rate" for TriviaQA (Q-Anchored and A-Anchored) drops significantly and remains low across all layers.
* The "I-Don't-Know Rate" for PopQA (Q-Anchored) tends to decrease as the layer increases.
* The "I-Don't-Know Rate" for PopQA (A-Anchored), HotpotQA (Q-Anchored and A-Anchored), and NQ (Q-Anchored and A-Anchored) remains relatively stable and high across all layers.
* The Llama-3-70B model has a longer x-axis (more layers) compared to Llama-3-8B.
### Interpretation
The charts illustrate how the "I-Don't-Know Rate" varies across different layers of the Llama-3-8B and Llama-3-70B models for different question-answering datasets and anchoring methods. The consistent low rate for TriviaQA suggests that both models are more confident in answering questions from this dataset, regardless of the layer. The decreasing rate for Q-Anchored PopQA indicates that the model becomes more certain about PopQA questions as it processes through deeper layers. The relatively stable and high rates for other datasets suggest that the model's confidence in answering those questions does not significantly change with increasing layer depth. The longer x-axis for Llama-3-70B indicates that it has more layers than Llama-3-8B, which could contribute to its potentially better performance in certain tasks.
