Type TruePositives
Namespace tensorflow.keras.metrics
Parent _ConfusionMatrixConditionCount
Interfaces ITruePositives
Calculates the number of true positives. For example, if `y_true` is [0, 1, 1, 1] and `y_pred` is [1, 0, 1, 1]
then the true positives value is 2. If the weights were specified as
[0, 0, 1, 0] then the true positives value would be 1. If `sample_weight` is given, calculates the sum of the weights of
true positives. This metric creates one local variable, `true_positives`
that is used to keep track of the number of true positives. If `sample_weight` is `None`, weights default to 1.
Use `sample_weight` of 0 to mask values. Usage:
Usage with tf.keras API:
Show Example
m = tf.keras.metrics.TruePositives() m.update_state([0, 1, 1, 1], [1, 0, 1, 1]) print('Final result: ', m.result().numpy()) # Final result: 2
