WebIntersection-Over-Union is a common evaluation metric for semantic image segmentation. For an individual class, the IoU metric is defined as follows: iou = true_positives / (true_positives + false_positives + false_negatives) To compute IoUs, the predictions are accumulated in a confusion matrix, weighted by sample_weight and the metric is then ...
