The charts are grouped by task (DisambiguationQA and tinyTruthfulQA) and method (Baseline, CoT - Chain of Thought, and Self-Consistency). Each chart plots the accuracy (%) of various models against the iteration number. The models are distinguished by color and marker type, as indicated in the legend at the bottom. ### Components/Axes * **Chart Titles (Top Row):** * DisambiguationQA - Baseline (top-left) * DisambiguationQA -

The data suggests that the choice of model and task significantly impacts accuracy. For instance, the "Multiple-choice" method seems less effective for the "tinyTruthfulQA" task, while the "Generation" method performs better on "tinyTruthfulQA" than on "DisambiguationQA". The relatively flat lines across iterations indicate that the models' performance does not significantly change with more iterations, suggesting that the models have reached a stable level of accuracy. The CoT and Self-Consistency methods, designed to improve reasoning, do not show a substantial advantage over the baseline, which could indicate that these tasks do not heavily rely on complex reasoning or that the models are not effectively utilizing these methods.

## Chart Type: Grid of Line Charts showing Model Accuracy over Iterations ### Overview The image displays a 2x3 grid of line charts, illustrating the accuracy of various language models across 6 iterations (0 to 5). The charts are categorized by two main question-answering (QA) datasets: "DisambiguationQA" (top row) and "tinyTruthfulQA" (bottom row), and three different inference strategies: "Baseline," "CoT" (Chain-of-Thought), and "Self-Consistency." Within each subplot, model performance is differentiated by two answer formats: "Generation" (blue lines) and "Multiple-choice" (orange lines), with specific markers identifying individual models. The Y-axis consistently represents "Accuracy (%)" and the X-axis represents "Iteration." ### Components/Axes **Overall Structure:** The image is divided into two main rows and three main columns, forming a 2x3 grid of individual line charts. **Row Titles (Implicit):** * **Top Row:** DisambiguationQA * **Bottom Row:** tinyTruthfulQA **Column Titles (Explicit, top of each subplot):** * **Column 1:** Baseline * **Column 2:** CoT * **Column 3:** Self-Consistency **Axes:** * **Common Y-axis Label (left-center):** Accuracy (%) * **Top Row (DisambiguationQA) Y-axis Range:** Approximately 0.0% to 0.4% (with minor ticks at 0.1, 0.2, 0.3). * **Bottom Row (tinyTruthfulQA) Y-axis Range:** Approximately 0.2% to 0.8% (with minor ticks at 0.4, 0.6). * **Common X-axis Label (bottom-center):** Iteration * **X-axis Range (all subplots):** 0 to 5 (with major ticks at 0, 1, 2, 3, 4, 5). **Legend (bottom-center, below all charts):** The legend defines the color for the answer format and the marker for the specific model. Each model has both a "Generation" (blue) and "Multiple-choice" (orange) line, using the same marker. * **Answer Format (Color):** * Blue Circle: Generation * Orange Circle: Multiple-choice * **Models (Marker & Name):** * Square: Gemini-2.0-Flash * Up-Triangle: Qwen2.5-14B * Down-Triangle: Llama-3.1-8B * Diamond: SmolLM2-1.7B * Left-Triangle: DeepSeek-R1-Distill-Llama-8B * Right-Triangle: Qwen2.5-3B *(Note: The legend shows grey markers for models, but in the plots, these markers appear in blue for "Generation" and orange for "Multiple-choice" lines. The blue and orange circles in the legend likely represent a generic "Generation" and "Multiple-choice" performance, or an unnamed baseline model, as lines with circle markers are present in the plots.)* ### Detailed Analysis The analysis is structured by row (QA dataset) and then by column (inference strategy). Within each subplot, general trends for "Generation" and "Multiple-choice" are described, followed by observations on specific models. --- #### **Row 1: DisambiguationQA** **1.

This suggests `tinyTruthfulQA` is an easier task or models are better suited for it. 2. **Answer Format Impact:** * For `DisambiguationQA`, "Multiple-choice" (orange lines) generally outperforms "Generation" (blue lines) across all inference strategies. The orange lines are consistently positioned above the blue lines. * For `tinyTruthfulQA`, "Generation" and "Multiple-choice" performances are largely comparable for most specific models. However, the generic "Multiple-choice" (orange circle) line is a significant outlier, showing very low accuracy (~0.15%) compared to all other models and the generic "Generation" line (~0.5%). 3. **Inference Strategy Impact (Baseline vs. CoT vs. Self-Consistency):** * For `DisambiguationQA`, there are no dramatic, consistent improvements across "Baseline," "CoT," and "Self-Consistency." Some models show minor fluctuations or slight peaks at early iterations with CoT/Self-Consistency, but overall performance levels remain similar. * For `tinyTruthfulQA`, the inference strategies (CoT, Self-Consistency) appear to have very little to no discernible impact on the accuracy of the models compared to the "Baseline" condition. The lines for each model largely overlap across the three columns. 4. **Model Performance:** * In `DisambiguationQA`, Gemini-2.0-Flash (square) and Qwen2.5-14B (up-triangle) generally show the highest accuracy among the models for both Generation and Multiple-choice. SmolLM2-1.7B (diamond) and Qwen2.5-3B (right-triangle) tend to be among the lower performers. * In `tinyTruthfulQA`, Gemini-2.0-Flash (square) and Qwen2.5-14B (up-triangle) again appear to be top performers, closely followed by DeepSeek-R1-Distill-Llama-8B (left-triangle) and Llama-3.1-8B (down-triangle). SmolLM2-1.7B (diamond) and Qwen2.5-3B (right-triangle) are generally lower, but still achieve high absolute accuracy compared to DisambiguationQA. 5. **Stability Across Iterations:** Most models show relatively stable performance across the 6 iterations, with some minor fluctuations. There are no strong, consistent upward or downward trends across iterations for the majority of the lines, suggesting that the iterative process might not be significantly improving or degrading performance within this range. ### Interpretation The data primarily demonstrates a significant difference in model performance based on the complexity or nature of the QA dataset. `tinyTruthfulQA` appears to be a much "easier" task for these models, with most achieving high accuracy (above 50-60%), while `DisambiguationQA` presents a considerably greater challenge, with accuracies generally below 45%. The choice between "Generation" and "Multiple-choice" answer formats has a notable impact on `DisambiguationQA`, where providing multiple-choice options consistently aids performance. This suggests that for more ambiguous or difficult tasks, the constrained choice space of multiple-choice questions helps models achieve better results, possibly by reducing the search space for correct answers or mitigating issues with open-ended generation. The anomalous low performance of the generic "Multiple-choice" (orange circle) line in `tinyTruthfulQA` is a curious outlier that warrants further investigation; it might represent a specific baseline or a different experimental setup not fully detailed in the legend. Crucially, the "CoT" and "Self-Consistency" inference strategies, often touted for improving reasoning and performance, show very limited, if any, consistent benefit across either dataset or model. For `tinyTruthfulQA`, their impact is negligible, with performance curves almost identical to the "Baseline." For `DisambiguationQA`, while some minor fluctuations or slight peaks are observed, there's no clear, sustained improvement over the baseline. This could imply that for these specific tasks and models, these advanced inference techniques do not provide a significant advantage, or that the iterative process itself (0-5 iterations) is not sufficient to fully leverage their potential. Alternatively, the tasks might not be complex enough in their reasoning demands to benefit from CoT or Self-Consistency, or the models themselves might not be sufficiently advanced to effectively utilize these techniques for substantial gains. The lack of strong trends across iterations further supports the idea that the models quickly reach a stable performance level, and further iterations within this range do not yield significant changes.

\n ## Line Charts: Model Performance on QA Tasks Across Iterations ### Overview The image presents six line charts comparing the performance of several language models on two question answering (QA) tasks – DisambiguationQA and tinyTruthfulQA – under three different prompting strategies: Baseline, Chain-of-Thought (CoT), and Self-Consistency. Performance is measured by accuracy (in percentage) across five iterations.

The prompting strategy (Baseline, CoT, Self-Consistency) has a moderate effect on performance, with no single strategy consistently outperforming the others. The "Multiple-choice" approach generally leads to better results than "Generation," potentially because it reduces the complexity of the task by providing a limited set of options. The stabilization of accuracy scores after a few iterations suggests that the models are converging towards their maximum performance level within the given experimental setup. The differences in performance between models (e.g., Gemini-2.0-Flash vs. SmolLM2-1.7B) highlight the varying capabilities of different language models. The relatively low accuracy scores for DisambiguationQA suggest that this task is more challenging and requires more sophisticated reasoning abilities.

## Line Charts: Model Accuracy Across Iterations on DisambiguationQA and tinyTruthfulQA ### Overview The image displays a 2x3 grid of six line charts comparing the performance of various large language models on two question-answering benchmarks ("DisambiguationQA" and "tinyTruthfulQA") across three prompting methods ("Baseline", "CoT" (Chain-of-Thought), and "Self-Consistency"). Performance is measured as accuracy percentage over 6 iterations (0 to 5). Each chart plots multiple lines, each representing a specific model, with line color indicating the task type (Generation or Multiple-choice) and marker shape indicating the specific model. ### Components/Axes * **Chart Grid:** 2 rows x 3 columns. * **Top Row Title:** `DisambiguationQA` * **Bottom Row Title:** `tinyTruthfulQA` * **Column Titles (Left to Right):** `Baseline`, `CoT`, `Self-Consistency` * **Axes (Identical for all charts):** * **X-axis:** Label: `Iteration`. Ticks: `0, 1, 2, 3, 4, 5`. * **Y-axis:** Label: `Accuracy (%)`. * Top Row (DisambiguationQA) Scale: `0.00` to `0.40` (increments of 0.10). * Bottom Row (tinyTruthfulQA) Scale: `0.0` to `0.8` (increments of 0.2). * **Legend (Located at the bottom center of the entire image):** * **Task Type (Color):** * Blue Circle: `Generation` * Orange Circle: `Multiple-choice` * **Model (Marker Shape & Label):** * Gray Square: `Gemini-2.0-Flash` * Gray Upward Triangle: `Qwen2.5-14B` * Gray Downward Triangle: `Llama-3.1-8B` * Gray Diamond: `SmolLM2-1.7B` * Gray Left Triangle: `DeepSeek-R1-Distill-Llama-8B` * Gray Right Triangle: `Qwen2.5-3B` * **Note:** The legend uses gray for all model markers. In the charts, the lines are colored blue or orange based on the task type, and the specific model is identified by its unique marker shape on that colored line. ### Detailed Analysis **1. DisambiguationQA - Baseline (Top-Left Chart)** * **Trend:** Performance is generally low and stable across iterations for most models. There is a clear separation between task types. * **Multiple-choice (Orange Lines):** Clustered in the upper band (~0.25 to ~0.38). The highest performer appears to be `Gemini-2.0-Flash` (square marker), starting near 0.38 and ending near 0.35. `Qwen2.5-14B` (up triangle) is also high, around 0.35. * **Generation (Blue Lines):** Clustered in the lower band (~0.05 to ~0.20). The highest blue line is likely `Qwen2.5-14B` (up triangle), hovering around 0.18-0.20. The lowest is `SmolLM2-1.7B` (diamond), near 0.05. **2. DisambiguationQA - CoT (Top-Middle Chart)** * **Trend:** More variability and some upward trends compared to Baseline. The gap between task types narrows slightly. * **Multiple-choice (Orange Lines):** Still generally higher, but with more fluctuation. `Gemini-2.0-Flash` (square) shows a dip at iteration 2 before recovering. Several models converge around 0.30-0.35 by iteration 5. * **Generation (Blue Lines):** Shows more improvement. The top blue line (likely `Qwen2.5-14B`, up triangle) rises from ~0.20 to ~0.28. Other models like `Llama-3.1-8B` (down triangle) also show upward movement. **3. DisambiguationQA - Self-Consistency (Top-Right Chart)** * **Trend:** The highest overall performance and most distinct separation between top and bottom performers. * **Multiple-choice (Orange Lines):** `Gemini-2.0-Flash` (square) is the clear leader, starting above 0.40 and maintaining a high level. `Qwen2.5-14B` (up triangle) is also strong, around 0.35-0.38. * **Generation (Blue Lines):** The top blue line (`Qwen2.5-14B`, up triangle) performs well, around 0.30-0.32. A significant outlier is the lowest blue line (`SmolLM2-1.7B`, diamond), which remains very low, near 0.05-0.08. **4. tinyTruthfulQA - Baseline (Bottom-Left Chart)** * **Trend:** Extremely wide spread in performance. Some models excel, while others fail almost completely. * **Multiple-choice (Orange Lines):** Two distinct clusters. Top cluster (`Gemini-2.0-Flash`, `Qwen2.5-14B`) is very high, ~0.75-0.80. Bottom cluster (`SmolLM2-1.7B`, `Qwen2.5-3B`) is very low, ~0.15-0.20. * **Generation (Blue Lines):** Similar wide spread. Top blue line (`Qwen2.5-14B`, up triangle) is high, ~0.70. Bottom blue line (`SmolLM2-1.7B`, diamond) is near 0.10. **5. tinyTruthfulQA - CoT (Bottom-Middle Chart)** * **Trend:** Performance for top models remains high but shows more volatility. The low-performing cluster remains consistently poor. * **Multiple-choice (Orange Lines):** Top models (`Gemini-2.0-Flash`, `Qwen2.5-14B`) fluctuate between 0.70 and 0.80. The low cluster (`SmolLM2-1.7B`, `Qwen2.5-3B`) stays flat near 0.20. * **Generation (Blue Lines):** The top blue line (`Qwen2.5-14B`, up triangle) shows a notable dip at iteration 2 before recovering to ~0.70. The lowest blue line remains near 0.10. **6. tinyTruthfulQA - Self-Consistency (Bottom-Right Chart)** * **Trend:** Similar pattern to CoT, with high performers maintaining a lead and low performers stagnant. * **Multiple-choice (Orange Lines):** `Gemini-2.0-Flash` (square) and `Qwen2.5-14B` (up triangle) are again top, ~0.75-0.80. The low cluster is unchanged. * **Generation (Blue Lines):** The top blue line (`Qwen2.5-14B`, up triangle) is stable around 0.70. The lowest blue line (`SmolLM2-1.7B`, diamond) shows a slight upward tick at iteration 5 but remains below 0.20. ### Key Observations 1. **Task Type Dominance:** Across all charts and methods, **Multiple-choice** tasks (orange lines) consistently yield higher accuracy than **Generation** tasks (blue lines) for the same model. 2. **Model Performance Hierarchy:** A clear hierarchy exists. `Gemini-2.0-Flash` and `Qwen2.5-14B` are consistently top performers. `SmolLM2-1.7B` and `Qwen2.5-3B` are consistently the lowest performers, especially on tinyTruthfulQA. 3. **Benchmark Difficulty:** Models achieve significantly higher accuracy on **tinyTruthfulQA** (up to ~80%) compared to **DisambiguationQA** (max ~40%), suggesting the latter is a more challenging benchmark for these models. 4. **Prompting Method Impact:** Moving from **Baseline** to **CoT** and **Self-Consistency** generally improves performance, particularly for Generation tasks on DisambiguationQA. The effect is less pronounced on tinyTruthfulQA for the top models, as they are already near a performance ceiling. 5. **Stability:** Performance is relatively stable across iterations for most models, with some notable fluctuations (e.g., `Qwen2.5-14B` on tinyTruthfulQA-CoT at iteration 2). ### Interpretation This data demonstrates the significant impact of both **task formulation** (Multiple-choice vs. Generation) and **prompting strategy** (Baseline, CoT, Self-Consistency) on LLM performance. The consistent superiority of Multiple-choice formats suggests that constrained output spaces are easier for models to handle accurately than open-ended generation for these QA tasks. The stark performance gap between models like `Gemini-2.0-Flash` and `SmolLM2-1.7B` highlights the importance of model scale and capability. The fact that advanced prompting (CoT, Self-Consistency) provides a larger relative boost to weaker models on the harder benchmark (DisambiguationQA) indicates these techniques are most valuable for bridging capability gaps in complex reasoning tasks. Conversely, on the easier benchmark (tinyTruthfulQA), top models are already proficient, so advanced prompting yields diminishing returns. The charts collectively argue that for reliable QA performance, one should consider: 1) using a capable base model, 2) framing the task as multiple-choice if possible, and 3) employing advanced prompting techniques like Self-Consistency, especially for challenging, ambiguous problems.

## Line Graphs: Model Performance Across Prompting Methods ### Overview The image contains six line graphs arranged in a 2x3 grid, comparing model accuracy across iterations (0-5) for two QA tasks: **DisambiguationQA** (top row) and **tinyTruthfulQA** (bottom row).

The decline in accuracy for some models (e.g., Llama 3.1-8B) over iterations may reflect overfitting or sensitivity to input variations. **tinyTruthfulQA** tasks are inherently more challenging, as evidenced by lower overall accuracy compared to DisambiguationQA. The stability of certain models (e.g., Gemini 2.0-Flash) highlights their robustness to iterative changes.
