# Technical Data Extraction: Execution Time Comparison ## 1. Image Classification This image is a **Bar Chart** comparing the execution times of nine different algorithms or systems. ## 2. Component Isolation ### Header/Title * **Content:** None present in the image. ### Y-Axis (Vertical) * **Label:** Execution Time /seconds * **Scale:** Linear, ranging from 0 to 120. * **Major Tick Marks:** 0, 20, 40, 60, 80, 100, 120. ### X-Axis (Horizontal) * **Categories:** Nine distinct labels representing different methods. * **Labels (Left to Right):** Kendall, Spearman, CloudScout, LOUD, AID, HALO, CMMD, KPIRoot, KPIRoot+. ### Main Data Area * **Type:** Single-series bar chart. * **Color Coding:** All bars are a uniform light aquamarine/mint green color with black outlines. * **Legend:** No legend is present as there is only one data series. --- ## 3. Data Table Extraction The following values are estimated based on the alignment of the top of each bar with the Y-axis grid markers. | Algorithm / Method | Estimated Execution Time (Seconds) | Visual Trend Description | | :--- | :--- | :--- | | **Kendall** | ~12 | Low baseline. | | **Spearman** | ~15 | Slightly higher than Kendall. | | **CloudScout** | ~13 | Comparable to Kendall/Spearman. | | **LOUD** | ~28 | Significant increase, roughly double the baseline. | | **AID** | ~117 | **Peak Value.** Highest execution time in the set. | | **HALO** | ~20 | Sharp decrease from AID, returning toward baseline. | | **CMMD** | ~84 | **Secondary Peak.** Second highest execution time. | | **KPIRoot** | ~5 | **Minimum Value.** Lowest execution time in the set. | | **KPIRoot+** | ~8 | Slight increase from KPIRoot, but still very low. | --- ## 4. Key Trends and Observations * **Performance Outliers:** The "AID" method is the clear outlier with the longest execution time, exceeding 110 seconds. "CMMD" is the second most time-intensive method at approximately 84 seconds. * **Efficiency Leaders:** "KPIRoot" and "KPIRoot+" demonstrate the highest efficiency (lowest execution time), both finishing in under 10 seconds. * **Baseline Group:** Kendall, Spearman, CloudScout, and HALO form a "middle-low" cluster with execution times ranging between 12 and 20 seconds. * **Comparison:** The execution time for AID is approximately 23 times longer than the execution time for KPIRoot. ## 5.
