Type BinaryAccuracy
Namespace tensorflow.keras.metrics
Parent MeanMetricWrapper
Interfaces IBinaryAccuracy
Calculates how often predictions matches labels. For example, if `y_true` is [1, 1, 0, 0] and `y_pred` is [0.98, 1, 0, 0.6]
then the binary accuracy is 3/4 or.75. If the weights were specified as
[1, 0, 0, 1] then the binary accuracy would be 1/2 or.5. This metric creates two local variables, `total` and `count` that are used to
compute the frequency with which `y_pred` matches `y_true`. This frequency is
ultimately returned as `binary accuracy`: an idempotent operation that simply
divides `total` by `count`. 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.BinaryAccuracy() m.update_state([1, 1, 0, 0], [0.98, 1, 0, 0.6]) print('Final result: ', m.result().numpy()) # Final result: 0.75
