Model evaluation.

Evaluation of final predicted penguin colony areas at Devil Island using mean intersection over union (mIoU), difference in perimeter to area ratio (PAR), area error, and accuracy (i.e. Fig 5 vs. ground truth). 95% confidence intervals are shown. We also show the evaluation of a fully manual approach. An up (down) arrow indicates a measure where a larger (smaller) number is preferred.本研究针对恶魔岛（Devil Island）的最终预测企鹅群落区域，采用交并比均值（mean intersection over union, mIoU）、周长面积比差值（difference in perimeter to area ratio, PAR）、区域误差以及准确率（即图5与真值（ground truth）的对比）开展评估，结果附带95%置信区间。我们同时展示了全手动方法的评估结果。文中向上（向下）箭头代表该指标的取值越大（越小）越优。
