Computes the mean absolute error between the labels and predictions.
Inherits From: MeanMetricWrapper, Mean, Metric
tf.keras.metrics.MeanAbsoluteError(
name='mean_absolute_error', dtype=None
)
Used in the notebooks

|---|
Formula:
loss = mean(abs(y_true - y_pred))
Args | |
|---|---|
name
|
(Optional) string name of the metric instance. |
dtype
|
(Optional) data type of the metric result. |
Examples:
m = keras.metrics.MeanAbsoluteError()m.update_state([[0, 1], [0, 0]], [[1, 1], [0, 0]])m.result()0.25m.reset_state()m.update_state([[0, 1], [0, 0]], [[1, 1], [0, 0]],sample_weight=[1, 0])m.result()0.5
Usage with compile() API:
model.compile(
optimizer='sgd',
loss='mse',
metrics=[keras.metrics.MeanAbsoluteError()])

Methods
add_variable
add_variable(
shape, initializer, dtype=None, aggregation='sum', name=None
)
add_weight
add_weight(
shape=(), initializer=None, dtype=None, name=None
)
from_config
@classmethodfrom_config( config )
get_config

Return the serializable config of the metric.
reset_state
reset_state()

This function is called between epochs/steps, when a metric is evaluated during training.
result
result()
Compute the current metric value.
