\n ## Bar Chart: Sparsity, L1 Norm, L2 Norm, and Gini Comparison with/without Transformation ### Overview This image presents a comparative bar chart showing the values of Sparsity, L1 Norm, L2 Norm, and Gini for three different models: Qwen2.5-7B-Math, Llama3.1-8B-Instruct, and Gemma3-4b-it. Each model is presented in two conditions: with transformation (left) and without transformation (right). The bars are color-coded, with a light blue/red scheme. Each chart also includes a density plot along the x-axis. ### Components/Axes * **X-axis:** Represents the metrics: Sparsity, L1 Norm, L2 Norm, and Gini. * **Y-axis:** Represents the values of the metrics, ranging from 0 to 700,000 (left charts) and 0 to 50,000 (middle chart) and 0 to 400,000 (right chart). * **Legend:** Located at the top-left corner, indicates that light blue bars represent "w/ transformation" and light red bars represent "w/o transformation". * **Model Labels:** Located at the bottom of each chart, identifying the model being analyzed: Qwen2.5-7B-Math, Llama3.1-8B-Instruct, and Gemma3-4b-it. * **Density Plots:** Red shaded areas along the x-axis, likely representing the distribution of values for each metric. ### Detailed Analysis or Content Details **Qwen2.5-7B-Math:** * **Sparsity (w/ transformation):** Approximately 0.185. * **L1 Norm (w/ transformation):** Approximately 0.160. * **L2 Norm (w/ transformation):** Approximately 0.120. * **Gini (w/ transformation):** Approximately 0.045. * **Sparsity (w/o transformation):** Approximately 0.0. * **L1 Norm (w/o transformation):** Approximately 0.0. * **L2 Norm (w/o transformation):** Approximately 0.0. * **Gini (w/o transformation):** Approximately 0.40. **Llama3.1-8B-Instruct:** * **Sparsity (w/ transformation):** Approximately 0.10. * **L1 Norm (w/ transformation):** Approximately 4.50. * **L2 Norm (w/ transformation):** Approximately 7.00. * **Gini (w/ transformation):** Approximately 4.30. * **Sparsity (w/o transformation):** Approximately 0.0. * **L1 Norm (w/o transformation):** Approximately 12.0. * **L2 Norm (w/o transformation):** Approximately 13.0. * **Gini (w/o transformation):** Approximately 5.00. **Gemma3-4b-it:** * **Sparsity (w/ transformation):** Approximately 0.10. * **L1 Norm (w/ transformation):** Approximately 1.4. * **L2 Norm (w/ transformation):** Approximately 0.6. * **Gini (w/ transformation):** Approximately 1.0. * **Sparsity (w/o transformation):** Approximately 0.6. * **L1 Norm (w/o transformation):** Approximately 0.0. * **L2 Norm (w/o transformation):** Approximately 0.0. * **Gini (w/o transformation):** Approximately 0.0. ### Key Observations * The "w/ transformation" condition consistently shows lower L1 and L2 Norm values compared to the "w/o transformation" condition for all three models. * Sparsity is generally low for the "w/o transformation" condition, often close to zero. * Gini values vary significantly between models and conditions. * The density plots show a concentration of values near zero for the "w/o transformation" condition, particularly for L1 and L2 Norms. ### Interpretation The data suggests that applying the transformation significantly impacts the sparsity, L1 norm, L2 norm, and Gini index of the models. The transformation appears to reduce the L1 and L2 norms, indicating a more compressed or regularized representation. The differences in Gini values suggest that the transformation affects the distribution of weights within the models. The near-zero values for L1 and L2 norms in the "w/o transformation" condition, coupled with the density plots, indicate that the models without transformation have a highly concentrated weight distribution, potentially leading to overfitting or reduced generalization ability. The transformation seems to introduce more diversity in the weight distribution, as reflected in the higher Gini values and non-zero L1/L2 norms. The Gemma3-4b-it model exhibits a particularly strong effect from the transformation, with a substantial decrease in L1 and L2 norms. This suggests that the transformation is more effective for this model.
