tf.compat.v1.tpu.experimental.AdagradParameters

Optimization parameters for Adagrad with TPU embeddings.

tf.compat.v1.tpu.experimental.AdagradParameters(
    learning_rate, initial_accumulator=0.1, 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_spec=tf.estimator.tpu.experimental.EmbeddingConfigSpec(
        ...
        optimization_parameters=tf.tpu.experimental.AdagradParameters(0.1),
        ...))

Args
learning_rate	used for updating embedding table.
initial_accumulator	initial accumulator for Adagrad.
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.
