\n ## Line Chart: ΔP vs. Layer for Mistral Models ### Overview The image presents two line charts, side-by-side, comparing the change in performance (ΔP) across different layers of two Mistral language models: Mistral-7B-v0.1 and Mistral-7B-v0.3. Each chart displays multiple lines representing different question-answering datasets and anchoring methods. The x-axis represents the layer number, and the y-axis represents ΔP. ### Components/Axes * **X-axis:** Layer (ranging from approximately 0 to 32). * **Y-axis:** ΔP (ranging from approximately -15 to 0). * **Left Chart Title:** Mistral-7B-v0.1 * **Right Chart Title:** Mistral-7B-v0.3 * **Legend (Bottom-Left):** * Q-Anchored (PopQA) - Blue solid line * A-Anchored (PopQA) - Orange dashed line * Q-Anchored (TriviaQA) - Purple solid line * A-Anchored (TriviaQA) - Red dashed line * Q-Anchored (HotpotQA) - Green dashed-dotted line * A-Anchored (HotpotQA) - Light Green dashed-dotted line * Q-Anchored (NQ) - Cyan solid line * A-Anchored (NQ) - Gray dashed line ### Detailed Analysis or Content Details **Mistral-7B-v0.1 (Left Chart):** * **Q-Anchored (PopQA):** The line starts at approximately ΔP = 0 at Layer 0, remains relatively stable around ΔP = 0 until Layer 18, then sharply declines to approximately ΔP = -14 at Layer 32. * **A-Anchored (PopQA):** The line starts at approximately ΔP = 0 at Layer 0, remains relatively stable around ΔP = -1 until Layer 18, then declines to approximately ΔP = -12 at Layer 32. * **Q-Anchored (TriviaQA):** The line starts at approximately ΔP = 0 at Layer 0, remains relatively stable around ΔP = 0 until Layer 18, then declines to approximately ΔP = -10 at Layer 32. * **A-Anchored (TriviaQA):** The line starts at approximately ΔP = 0 at Layer 0, remains relatively stable around ΔP = -1 until Layer 18, then declines to approximately ΔP = -11 at Layer 32. * **Q-Anchored (HotpotQA):** The line starts at approximately ΔP = 0 at Layer 0, remains relatively stable around ΔP = -1 until Layer 18, then declines to approximately ΔP = -10 at Layer 32. * **A-Anchored (HotpotQA):** The line starts at approximately ΔP = 0 at Layer 0, remains relatively stable around ΔP = -1 until Layer 18, then declines to approximately ΔP = -11 at Layer 32. * **Q-Anchored (NQ):** The line starts at approximately ΔP = 0 at Layer 0, remains relatively stable around ΔP = 0 until Layer 18, then declines to approximately ΔP = -8 at Layer 32. * **A-Anchored (NQ):** The line starts at approximately ΔP = 0 at Layer 0, remains relatively stable around ΔP = -1 until Layer 18, then declines to approximately ΔP = -10 at Layer 32. **Mistral-7B-v0.3 (Right Chart):** * **Q-Anchored (PopQA):** The line starts at approximately ΔP = 0 at Layer 0, remains relatively stable around ΔP = 0 until Layer 18, then declines to approximately ΔP = -8 at Layer 32. * **A-Anchored (PopQA):** The line starts at approximately ΔP = 0 at Layer 0, remains relatively stable around ΔP = -1 until Layer 18, then declines to approximately ΔP = -7 at Layer 32. * **Q-Anchored (TriviaQA):** The line starts at approximately ΔP = 0 at Layer 0, remains relatively stable around ΔP = 0 until Layer 18, then declines to approximately ΔP = -6 at Layer 32. * **A-Anchored (TriviaQA):** The line starts at approximately ΔP = 0 at Layer 0, remains relatively stable around ΔP = -1 until Layer 18, then declines to approximately ΔP = -7 at Layer 32. * **Q-Anchored (HotpotQA):** The line starts at approximately ΔP = 0 at Layer 0, remains relatively stable around ΔP = -1 until Layer 18, then declines to approximately ΔP = -7 at Layer 32. * **A-Anchored (HotpotQA):** The line starts at approximately ΔP = 0 at Layer 0, remains relatively stable around ΔP = -1 until Layer 18, then declines to approximately ΔP = -8 at Layer 32. * **Q-Anchored (NQ):** The line starts at approximately ΔP = 0 at Layer 0, remains relatively stable around ΔP = 0 until Layer 18, then declines to approximately ΔP = -5 at Layer 32. * **A-Anchored (NQ):** The line starts at approximately ΔP = 0 at Layer 0, remains relatively stable around ΔP = -1 until Layer 18, then declines to approximately ΔP = -6 at Layer 32. ### Key Observations * In both models, all lines exhibit a relatively flat trend until approximately Layer 18, after which they begin to decline. * The decline in ΔP is more pronounced in Mistral-7B-v0.1 than in Mistral-7B-v0.3. * Q-Anchored lines generally show a larger decline in ΔP compared to A-Anchored lines. * PopQA consistently shows the largest decline in ΔP. ### Interpretation The charts illustrate how the performance of the Mistral models changes across different layers, as measured by ΔP for various question-answering datasets and anchoring methods. The initial stability suggests that the early layers contribute relatively equally to performance across datasets. The subsequent decline, particularly after Layer 18, indicates that deeper layers may be less effective or even detrimental to performance, potentially due to overfitting or the emergence of undesirable behaviors. The difference between the two models (v0.1 vs. v0.3) suggests that the newer version (v0.3) exhibits improved stability and less performance degradation in deeper layers. The variations between datasets (PopQA, TriviaQA, HotpotQA, NQ) highlight the sensitivity of performance to the specific characteristics of the question-answering task. The anchoring method (Q-Anchored vs. A-Anchored) also influences performance, with Q-Anchored generally showing a greater decline, potentially indicating that anchoring questions is more sensitive to layer depth than anchoring answers. The consistent decline across most lines suggests a systematic issue, while the differences between lines point to specific areas for further investigation and optimization. The charts provide valuable insights into the behavior of these language models and can guide efforts to improve their performance and robustness.
