Evaluation-related metrics.

Members

auc(...): Computes the approximate AUC via a Riemann sum.

false_negatives(...): Computes the total number of false positives.

false_positives(...): Sum the weights of false positives.

mean(...): Computes the (weighted) mean of the given values.

mean_absolute_error(...): Computes the mean absolute error between the labels and predictions.

mean_cosine_distance(...): Computes the cosine distance between the labels and predictions.

mean_iou(...): Calculate per-step mean Intersection-Over-Union (mIOU).

mean_relative_error(...): Computes the mean relative error by normalizing with the given values.

mean_squared_error(...): Computes the mean squared error between the labels and predictions.

mean_tensor(...): Computes the element-wise (weighted) mean of the given tensors.

percentage_below(...): Computes the percentage of values less than the given threshold.

precision(...): Computes the precision of the predictions with respect to the labels.

precision_at_thresholds(...): Computes precision values for different thresholds on predictions.

recall(...): Computes the recall of the predictions with respect to the labels.

recall_at_k(...): Computes recall@k of the predictions with respect to sparse labels.

recall_at_thresholds(...): Computes various recall values for different thresholds on predictions.
