Update entries in '*var' and '*accum' according to the proximal adagrad scheme.

tf.raw_ops.ResourceSparseApplyAdagradDA( var, gradient_accumulator, gradient_squared_accumulator, grad, indices, lr, l1, l2, global_step, use_locking=False, name=None )

Args | |
---|---|

`var` | A `Tensor` of type `resource` . Should be from a Variable(). |

`gradient_accumulator` | A `Tensor` of type `resource` . Should be from a Variable(). |

`gradient_squared_accumulator` | A `Tensor` of type `resource` . Should be from a Variable(). |

`grad` | A `Tensor` . Must be one of the following types: `float32` , `float64` , `int32` , `uint8` , `int16` , `int8` , `complex64` , `int64` , `qint8` , `quint8` , `qint32` , `bfloat16` , `uint16` , `complex128` , `half` , `uint32` , `uint64` . The gradient. |

`indices` | A `Tensor` . Must be one of the following types: `int32` , `int64` . A vector of indices into the first dimension of var and accum. |

`lr` | A `Tensor` . Must have the same type as `grad` . Learning rate. Must be a scalar. |

`l1` | A `Tensor` . Must have the same type as `grad` . L1 regularization. Must be a scalar. |

`l2` | A `Tensor` . Must have the same type as `grad` . L2 regularization. Must be a scalar. |

`global_step` | A `Tensor` of type `int64` . Training step number. Must be a scalar. |

`use_locking` | An optional `bool` . Defaults to `False` . If True, updating of the var and accum tensors will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention. |

`name` | A name for the operation (optional). |

Returns | |
---|---|

The created Operation. |
