Accepts the following input To analyze traffic and optimize your experience, we serve cookies on this site. Accepts the following input tensors: preds (int or float tensor): (N,). TP/(TP+FN). Their shape depends on the average parameter. For object detection the recall and precision are defined based on the intersection of union (IoU) between the predicted bounding boxes and the ground truth bounding boxes e. The curve consist of multiple pairs of precision and recall values evaluated at different thresholds, such that the tradeoff between the two values can been seen. The number of outputs is now automatically inferred from the shape of the input tensors. Base interface¶ Classwise Wrapper¶ Module Interface¶ class torchmetrics.
