了解模型評估任務的結果如何儲存在 Amazon S3 中

模型評估任務的輸出會儲存在您建立模型評估任務時指定的 Amazon S3 儲存貯體中。模型評估任務的結果會儲存為JSON行檔案 (.jsonl)。

模型評估任務的結果會儲存在您指定的 S3 儲存貯體中，如下所示。

下列主題說明如何將自動化和人力型模型評估任務的結果儲存在 Amazon S3 中。

從自動化模型評估任務輸出資料

當任務狀態變更為已完成時，自動化評估任務的結果會儲存在 datasets 目錄中。

對於您在建立模型評估任務時選取的每個指標和對應的提示資料集， datasets 目錄中會產生一JSON行檔案。該檔案會使用以下命名慣例 metric_input-dataset.jsonl。

模型評估任務的每個結果都以 automatedEvaluationResult 鍵起始。第一個子鍵 scores 包含您在 Amazon Bedrock 主控台選取的指標。在此範例中，僅選取單一指標 Accuracy。另外也包含 result，此為所選指標的計算值。若要進一步了解計算哪些特定值，請參閱 在 Amazon Bedrock 中檢閱自動化模型評估任務的指標 （主控台）。

第二個鍵 inputRecord 是您在輸入提示資料集中提供的內容複本。

第三個索引鍵modelResponses包含JSON物件清單，其中包含您建立模型評估任務時所選取模型ARN的 。另外還包含根據提供的提示的模型的完整回應。

以下是文字摘要任務類型的範例輸出，只選取一個指標 (準確度)。

In HIIT, you perform exercises at near-maximum effort during the high-intensity intervals, which can include activities like sprinting, cycling, jumping, or body weight exercises such as burpees or push-ups. These intense intervals are interspersed with short recovery periods to lower your heart rate before the next high-intensity bout. HIIT workouts usually consist of multiple cycles of these intervals, and the number of cycles and the length of intervals can vary. HIIT is known for its time efficiency, making it an excellent choice for those with busy schedules. It offers both aerobic and anaerobic benefits, improving cardiovascular fitness, burning calories, and promoting fat loss, all while boosting metabolism for continued calorie burning post-workout."

Here are some key features of HIIT:\n\n- Alternates short periods of intense anaerobic exercise with less intense recovery periods. The high-intensity periods are typically done at 80-95% of maximum heart rate.\n\n- The duration of the intense periods can range from 5 seconds to 8 minutes, but typically are in the range of 30 seconds to 4 minutes.\n\n- The total HIIT session typically lasts between 10-30 minutes, including warm-up, recovery periods, and cool down. \n\n- Uses exercises like sprints, cycling, rowing, jumping rope, stair climbing, swimming, etc. Movements that get your heart rate up quickly.\n\n- The short, intense intervals help improve cardiovascular fitness by increasing heart rate and oxygen consumption.\n\n- HIIT burns more calories and fat than steady-state cardio in a shorter time period. It also helps build muscle strength and endurance.\n\n- Considered an efficient and effective form of exercise for fat loss and improving aerobic power. But it requires motivation to push yourself during the intense intervals.\n\n- Not suitable for beginners due to the high-intensity. Start with steady-state cardio and build up endurance before trying HIIT.\n\nIn summary, HIIT intersperses intense bursts of"
