**Instance Normalization Layer**
Can be used as a normalizer function for convolution or fully_connected operations.
The required data format for this layer is one of the following:
DataLayout: NCHW `[batch, in_channels, in_height, in_width]`
Refer to `Instance Normalization: The Missing Ingredient for
Fast Stylization <https://arxiv.org/pdf/1607.08022.pdf>`_
for more details.
:math:`input` is the input features over a mini-batch.
.. math::
\\mu_{\\beta} &\\gets \\frac{1}{HW} \\sum_{i=1}^{HW} x_i \\qquad &//\\
\\ mean\ of\ one\ feature\ map\ in\ mini-batch \\\\
\\sigma_{\\beta}^{2} &\\gets \\frac{1}{HW} \\sum_{i=1}^{HW}(x_i - \\
\\mu_{\\beta})^2 \\qquad &//\ variance\ of\ one\ feature\ map\ in\ mini-batch \\\\
\\hat{x_i} &\\gets \\frac{x_i - \\mu_\\beta} {\\sqrt{\\
\\sigma_{\\beta}^{2} + \\epsilon}} \\qquad &//\ normalize \\\\
y_i &\\gets \\gamma \\hat{x_i} + \\beta \\qquad &//\ scale\ and\ shift
Note:
`H` means height of feature map, `W` means width of feature map.
Args:
input(Tensor): The rank of input tensor can be 2, 3, 4, 5.
The data type is float32 or float64.
epsilon(float, Default 1e-05): A value added to the denominator for
numerical stability. Default is 1e-5.
param_attr(ParamAttr|None|bool, optional): The parameter attribute for Parameter `scale`
of instance_norm. If it is set to None or one attribute of ParamAttr, instance_norm
will create ParamAttr as param_attr, the name of scale can be set in ParamAttr.
If the Initializer of the param_attr is not set, the parameter is initialized
with Xavier. If the param_attr is set to False, instance_norm will not create param_attr.
Default: None.
bias_attr(ParamAttr|None|bool, optional): The parameter attribute for the bias of instance_norm.
If it is set to None or one attribute of ParamAttr, instance_norm
will create ParamAttr as bias_attr, the name of bias can be set in ParamAttr.
If the Initializer of the bias_attr is not set, the bias is initialized zero.
If the bias_attr is set to False, instance_norm will not create bias_attr.
Default: None.
name(string, Default None): A name for this layer(optional). If set None, the layer
will be named automatically.
Returns:
A Tensor which is the result after applying instance normalization on the input,
has same shape and data type with input.
Examples:

**Data Normalization Layer**
This op can be used as a normalizer function for conv2d and fully_connected operations.
The required data format for this layer is one of the following:
1. NHWC `[batch, in_height, in_width, in_channels]`
2. NCHW `[batch, in_channels, in_height, in_width]`
:math:`input` is the input features over a mini-batch.
.. math::
\\mu_{\\beta} &\\gets \\frac{1}{m} \\sum_{i=1}^{m} x_i \\qquad &//\\
\ mini-batch\ mean \\\\
\\sigma_{\\beta}^{2} &\\gets \\frac{1}{m} \\sum_{i=1}^{m}(x_i - \\

\\hat{x_i} &\\gets \\frac{x_i - \\mu_\\beta} {\\sqrt{\\
\\sigma_{\\beta}^{2} + \\epsilon}} \\qquad &//\ normalize \\\\
y_i &\\gets \\gamma \\hat{x_i} + \\beta \\qquad &//\ scale\ and\ shift
Args:
input(Tensor): The input Tensor.
act(string, Default None): Activation type, linear|relu|prelu|...
epsilon(float, Default 1e-05):
param_attr(ParamAttr): The parameter attribute for Parameter `scale`.
data_layout (str, optional): Specify the data format of the input, and the data format of the output
will be consistent with that of the input. An optional string from: `"NCHW"`, `"NHWC"`.
The default is `"NCHW"`. When it is `"NCHW"`, the data is stored in the order of:
`[batch_size, input_channels, input_height, input_width]`.
in_place(bool, Default False): Make the input and output of batch norm reuse memory.
name(string, Default None): A name for this layer(optional). If set None, the layer
will be named automatically.
moving_mean_name(string, Default None): The name of moving_mean which store the global Mean.
moving_variance_name(string, Default None): The name of the moving_variance which store the global Variance.
do_model_average_for_mean_and_var(bool, Default True): Whether parameter mean and variance
should do model average when model average is enabled.
slot_dim(int): The embedding dimension of one slot. Slot is a set of one specific feature. In pslib mode, we
distinguish feature ids by slot and pull their embeddings from parameter server (pslib). The first
place of the embedding is the historical show number (occurence time of this feature id with a label 0).
If the input of this op is concated by slot-wise embeddings, and the show number is zero when this slot
is new or empty, the normalization result may be impractical. To avoid this, we add slot_dim to locate
the show number and judge if the show number is zero. If so, we choose to skip normalization on this
embedding.
sync_stats(bool, Default False): When running with multiple GPU cards, using allreduce to sync the
summary messages.
summary_decay_rate(float, Default 0.9999999): The decay rate when updating summary.
enable_scale_and_shift(bool, Default False): do scale&shift after normalization.
Returns:
Tensor: A tensor which is the result after applying data normalization on the input.

**Instance Normalization Layer**
Can be used as a normalizer function for convolution or fully_connected operations.
The required data format for this layer is one of the following:
DataLayout: NCHW `[batch, in_channels, in_height, in_width]`
Refer to `Instance Normalization: The Missing Ingredient for
Fast Stylization <https://arxiv.org/pdf/1607.08022.pdf>`_
for more details.
:math:`input` is the input features over a mini-batch.
.. math::
\\mu_{\\beta} &\\gets \\frac{1}{HW} \\sum_{i=1}^{HW} x_i \\qquad &//\\
\\ mean\ of\ one\ feature\ map\ in\ mini-batch \\\\
\\sigma_{\\beta}^{2} &\\gets \\frac{1}{HW} \\sum_{i=1}^{HW}(x_i - \\
\\mu_{\\beta})^2 \\qquad &//\ variance\ of\ one\ feature\ map\ in\ mini-batch \\\\
\\hat{x_i} &\\gets \\frac{x_i - \\mu_\\beta} {\\sqrt{\\
\\sigma_{\\beta}^{2} + \\epsilon}} \\qquad &//\ normalize \\\\
y_i &\\gets \\gamma \\hat{x_i} + \\beta \\qquad &//\ scale\ and\ shift
Note:
`H` means height of feature map, `W` means width of feature map.
Args:
input(Tensor): The rank of input tensor can be 2, 3, 4, 5.
The data type is float32 or float64.
epsilon(float, Default 1e-05): A value added to the denominator for
numerical stability. Default is 1e-5.
param_attr(ParamAttr|None|bool, optional): The parameter attribute for Parameter `scale`
of instance_norm. If it is set to None or one attribute of ParamAttr, instance_norm
will create ParamAttr as param_attr, the name of scale can be set in ParamAttr.
If the Initializer of the param_attr is not set, the parameter is initialized
with Xavier. If the param_attr is set to False, instance_norm will not create param_attr.
Default: None.
bias_attr(ParamAttr|None|bool, optional): The parameter attribute for the bias of instance_norm.
If it is set to None or one attribute of ParamAttr, instance_norm
will create ParamAttr as bias_attr, the name of bias can be set in ParamAttr.
If the Initializer of the bias_attr is not set, the bias is initialized zero.
If the bias_attr is set to False, instance_norm will not create bias_attr.
Default: None.
name(string, Default None): A name for this layer(optional). If set None, the layer
will be named automatically.
Returns:
A Tensor which is the result after applying instance normalization on the input,
has same shape and data type with input.

**Data Normalization Layer**
This op can be used as a normalizer function for conv2d and fully_connected operations.
The required data format for this layer is one of the following:
1. NHWC `[batch, in_height, in_width, in_channels]`
2. NCHW `[batch, in_channels, in_height, in_width]`
:math:`input` is the input features over a mini-batch.

\\sigma_{\\beta}^{2} + \\epsilon}} \\qquad &//\ normalize \\\\
y_i &\\gets \\gamma \\hat{x_i} + \\beta \\qquad &//\ scale\ and\ shift
Args:
input(Tensor): The input Tensor.
act(string, Default None): Activation type, linear|relu|prelu|...
epsilon(float, Default 1e-05):
param_attr(ParamAttr): The parameter attribute for Parameter `scale`.
data_layout (str, optional): Specify the data format of the input, and the data format of the output
will be consistent with that of the input. An optional string from: `"NCHW"`, `"NHWC"`.
The default is `"NCHW"`. When it is `"NCHW"`, the data is stored in the order of:
`[batch_size, input_channels, input_height, input_width]`.
in_place(bool, Default False): Make the input and output of batch norm reuse memory.
name(string, Default None): A name for this layer(optional). If set None, the layer
will be named automatically.
moving_mean_name(string, Default None): The name of moving_mean which store the global Mean.
moving_variance_name(string, Default None): The name of the moving_variance which store the global Variance.
do_model_average_for_mean_and_var(bool, Default True): Whether parameter mean and variance
should do model average when model average is enabled.
slot_dim(int): The embedding dimension of one slot. Slot is a set of one specific feature. In pslib mode, we
distinguish feature ids by slot and pull their embeddings from parameter server (pslib). The first
place of the embedding is the historical show number (occurence time of this feature id with a label 0).
If the input of this op is concated by slot-wise embeddings, and the show number is zero when this slot
is new or empty, the normalization result may be impractical. To avoid this, we add slot_dim to locate
the show number and judge if the show number is zero. If so, we choose to skip normalization on this
embedding.
sync_stats(bool, Default False): When running with multiple GPU cards, using allreduce to sync the
summary messages.
summary_decay_rate(float, Default 0.9999999): The decay rate when updating summary.
enable_scale_and_shift(bool, Default False): do scale&shift after normalization.
Returns:
Tensor: A tensor which is the result after applying data normalization on the input.

:api_attr: Static Graph
**Group Normalization Layer**
Refer to `Group Normalization <https://arxiv.org/abs/1803.08494>`_ .
Parameters:
input(Tensor): Tensor with dimension greater than 1, the data type is float32 or float64.
groups(int): The number of groups that divided from channels, the data type
is int32.
epsilon(float, optional): The small value added to the variance to prevent
division by zero, the data type is float32. Default: 1e-05.
param_attr(ParamAttr|bool, optional): ParamAttr object that specifies weight parameter
attribute. If a bool type, only False is supported, which means there is no weight parameter.
Default: None, the default weight parameter attribute is used. For more information, please
refer to :ref:`api_guide_ParamAttr` .
bias_attr(ParamAttr|bool, optional): ParamAttr object that specifies bias parameter
attribute. If a bool type, only False is supported, which means there is no bias parameter.
Default: None, the default bias parameter attribute is used. For more information, please
refer to :ref:`api_guide_ParamAttr` .
act(str, optional): Activation to be applied to the output of group normalization.
data_layout(str, optional): Specify the data format of the input, and the data format of the output
will be consistent with that of the input. An optional string from: `"NCHW"`, `"NHWC"`.
The default is `"NCHW"`. When it is `"NCHW"`, the data is stored in the order of:
`[batch_size, input_channels, *]`.
name (str, optional): The default value is None. Normally there is no need for user to set this
property. For more information, please refer to :ref:`api_guide_Name` .
Returns:
Tensor: A Tensor has same data type and data format with `input`.
