tf.compat.v1.tpu.experimental.AdamParameters

tf.tpu.experimental.AdamParameters(
    learning_rate, beta1=0.9, beta2=0.999, epsilon=1e-08, lazy_adam=True,
    sum_inside_sqrt=True, use_gradient_accumulation=True, clip_weight_min=None,
    clip_weight_max=None
)

Pass this to tf.estimator.tpu.experimental.EmbeddingConfigSpec via the optimization_parameters argument to set the optimizer and its parameters. See the documentation for tf.estimator.tpu.experimental.EmbeddingConfigSpec for more details.

estimator = tf.estimator.tpu.TPUEstimator(
    ...
    embedding_config_spec=tf.estimator.tpu.experimental.EmbeddingConfigSpec(
        ...
        optimization_parameters=tf.tpu.experimental.AdamParameters(0.1),
        ...))

Args
learning_rate	a floating point value. The learning rate.
beta1	A float value. The exponential decay rate for the 1st moment estimates.
beta2	A float value. The exponential decay rate for the 2nd moment estimates.
epsilon	A small constant for numerical stability.
lazy_adam	Use lazy Adam instead of Adam. Lazy Adam trains faster. Please see optimization_parameters.proto for details.
sum_inside_sqrt	This improves training speed. Please see optimization_parameters.proto for details.
use_gradient_accumulation	setting this to False makes embedding gradients calculation less accurate but faster. Please see optimization_parameters.proto for details. for details.
clip_weight_min	the minimum value to clip by; None means -infinity.
clip_weight_max	the maximum value to clip by; None means +infinity.
