## Line Chart: Pass@k vs. k ### Overview The image is a line chart comparing the performance of four different methods (RL, SFT, MT, and Base) based on the "Pass@k" metric for varying values of 'k' (1, 2, and 3). The chart displays the percentage of successful attempts (Pass@k) on the y-axis against the value of 'k' on the x-axis. ### Components/Axes * **X-axis:** Labeled "k" with values 1, 2, and 3. * **Y-axis:** Labeled "Pass@k (%)" with values ranging from 0.0 to 12.5, incrementing by 2.5. * **Legend:** Located in the top-left corner, associating colors with methods: * Red: RL * Orange: SFT * Purple: MT * Blue: Base ### Detailed Analysis * **RL (Red):** The line slopes upward. * k=1: Approximately 4.8% * k=2: Approximately 7.2% * k=3: Approximately 9.4% * **SFT (Orange):** The line slopes upward. * k=1: Approximately 4.5% * k=2: Approximately 8.0% * k=3: Approximately 11.0% * **MT (Purple):** The line slopes slightly upward. * k=1: Approximately 1.8% * k=2: Approximately 2.0% * k=3: Approximately 2.4% * **Base (Blue):** The line slopes slightly upward. * k=1: Approximately 1.1% * k=2: Approximately 2.0% * k=3: Approximately 2.6% ### Key Observations * SFT consistently outperforms RL across all values of k. * MT and Base have significantly lower Pass@k values compared to RL and SFT. * All methods show an increase in Pass@k as k increases from 1 to 3. * The performance gap between SFT/RL and MT/Base is substantial. ### Interpretation The chart suggests that SFT and RL are significantly more effective methods than MT and Base, as indicated by their higher Pass@k values. The increasing trend of Pass@k for all methods as 'k' increases implies that allowing more attempts ('k') leads to a higher success rate. The large performance difference between SFT/RL and MT/Base could be due to differences in their underlying algorithms or training methodologies.
