Optimization parameters for Adagrad with TPU embeddings.

    tf.compat.v1.tpu.experimental.AdagradParameters(
        learning_rate: float,
        initial_accumulator: float = 0.1,
        use_gradient_accumulation: bool = True,
        clip_weight_min: Optional[float] = None,
        clip_weight_max: Optional[float] = None,
        weight_decay_factor: Optional[float] = None,
        multiply_weight_decay_factor_by_learning_rate: Optional[bool] = None,
        clip_gradient_min: Optional[float] = None,
        clip_gradient_max: Optional[float] = 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. |
| `clip_weight_min` | the minimum value to clip by; None means -infinity. |
| `clip_weight_max` | the maximum value to clip by; None means +infinity. |
| `weight_decay_factor` | amount of weight decay to apply; None means that the weights are not decayed. |
| `multiply_weight_decay_factor_by_learning_rate` | if true, `weight_decay_factor` is multiplied by the current learning rate. |
| `clip_gradient_min` | the minimum value to clip by; None means -infinity. Gradient accumulation must be set to true if this is set. |
| `clip_gradient_max` | the maximum value to clip by; None means +infinity. Gradient accumulation must be set to true if this is set. |
