### <a name="com.microsoft.Attention"></a><a name="com.microsoft.attention">**com.microsoft.Attention**</a>

  Multi-Head Attention that can be either unidirectional (like GPT-2) or bidirectional (like BERT).
  
  The weights for input projection of Q, K and V are merged. The data is stacked on the second dimension. Its shape
  is (input_hidden_size, hidden_size + hidden_size + v_hidden_size). Here hidden_size is the hidden dimension of Q and K,
  and v_hidden_size is that of V.
  
  The mask_index is optional. Besides raw attention mask with shape (batch_size, total_sequence_length)
  or (batch_size, sequence_length, total_sequence_length) with value 0 for masked and 1 otherwise,
  we support other two formats: When input has right-side padding, mask_index is one dimension with shape (batch_size),
  where value is actual sequence length excluding padding. When input has left-side padding, mask_index has
  shape (2 * batch_size), where the values are the exclusive end positions followed by the inclusive start positions.
  
  When unidirectional is 1, each token only attends to previous tokens.
  
  Both past and present state are optional. They shall be used together, and not allowed to use only one of them.
  
  When weights is not provided, key and value are required. In this situation, MatMul for input projection is excluded,
  and input is the query after projection. The bias is included for performance consideration.
  
  The qkv_hidden_sizes is required only when K and V have different hidden sizes.
  
  When there is past state, hidden dimension for Q, K and V shall be the same.
  
  The total_sequence_length is past_sequence_length + kv_sequence_length. Here kv_sequence_length is the length of K or V.
  For self attention, kv_sequence_length equals to sequence_length (sequence length of Q).
  For cross attention, query and key might have different lengths.

### <a name="com.microsoft.BitmaskDropout"></a><a name="com.microsoft.bitmaskdropout">**com.microsoft.BitmaskDropout**</a>

  BitmaskDropout takes an input floating-point tensor, an optional input ratio (floating-point scalar) and an optional input training_mode (boolean scalar).
  It produces two tensor outputs: output (floating-point tensor) and mask (optional `Tensor<uint32>`). If `training_mode` is true then the output Y will be a random dropout.
  Note that this Dropout scales the masked input data by the following equation, so to convert the trained model into inference mode, the user can simply not pass `training_mode` input or set it to false.
  ```
  output = scale * data * mask,
  ```
  where
  ```
  scale = 1. / (1. - ratio).
  ```
  
  This op functions in much the same was as Dropout-11 and Dropout-13 do, execpt that the mask is output as a bit-packed uint32 tensor, instead of a boolean tensor.

### <a name="com.microsoft.GridSample"></a><a name="com.microsoft.gridsample">**com.microsoft.GridSample**</a>

  Given an `input` and a flow-field `grid`, computes the `output` using `input` values and pixel locations from `grid`.
        Currently, only spatial (4-D) inputs are supported. For `input` with shape (N, C, H, W) and `grid` with shape (N, H_out, W_out, 2),
        the `output` will have shape (N, C, H_out, W_out).
        For each output location `output[n, :, h, w]`, the size-2 vector `grid[n, h, w]` specifies `input` pixel locations `x` and `y`,
        which are used to interpolate the output value `output[n, :, h, w]`.
        The GridSample operator is often used in doing grid generator and sampler in the [Spatial Transformer Networks](https://arxiv.org/abs/1506.02025).
        See also in [torch.nn.functional.grid_sample](https://pytorch.org/docs/master/generated/torch.nn.functional.grid_sample.html#torch-nn-functional-grid-sample).
        

#### Version

#### Attributes

<dl>
<dt><tt>align_corners</tt> : int</dt>
<dd>If align_corners=1, the extrema (-1 and 1) are considered as referring to the center points of the input's corner pixels. If align_corners=0, they are instead considered as referring to the corner points of the input's corner pixels, making the sampling more resolution agnostic.</dd>
<dt><tt>mode</tt> : string</dt>
<dd>Three interpolation modes: bilinear (default), nearest and bicubic.</dd>
<dt><tt>padding_mode</tt> : string</dt>
<dd>Support padding modes for outside grid values: `zeros`(default), `border`, `reflection`. zeros: use 0 for out-of-bound grid locations, border: use border values for out-of-bound grid locations, reflection: use values at locations reflected by the border for out-of-bound grid locations.</dd>

  Longformer Self Attention with a local context and a global context. Tokens attend locally: Each token
  attends to its W previous tokens and W succeeding tokens with W being the window length. A selected few tokens
  attend globally to all other tokens.
  
  The attention mask is of shape (batch_size, sequence_length), where sequence_length is a multiple of 2W after padding.
  Mask value < 0 (like -10000.0) means the token is masked, 0 otherwise.
  
  Global attention flags have value 1 for the tokens attend globally and 0 otherwise.

### <a name="com.microsoft.QLinearAveragePool"></a><a name="com.microsoft.qlinearaveragepool">**com.microsoft.QLinearAveragePool**</a>

  QLinearAveragePool consumes an input tensor X and applies average pooling across
   the tensor according to kernel sizes, stride sizes, and pad lengths.
   average pooling consisting of computing the average on all values of a
   subset of the input tensor according to the kernel size and downsampling the
   data into the output tensor Y for further processing. The output spatial shape will be following:
   ```
   output_spatial_shape[i] = floor((input_spatial_shape[i] + pad_shape[i] - kernel_spatial_shape[i]) / strides_spatial_shape[i] + 1)
   ```
   or
   ```
   output_spatial_shape[i] = ceil((input_spatial_shape[i] + pad_shape[i] - kernel_spatial_shape[i]) / strides_spatial_shape[i] + 1)
   ```
   if ceil_mode is enabled
  
   ```
   * pad_shape[i] is sum of pads along axis i
   ```
  
   `auto_pad` is a DEPRECATED attribute. If you are using them currently, the output spatial shape will be following:
   ```
   VALID: output_spatial_shape[i] = ceil((input_spatial_shape[i] - kernel_spatial_shape[i] + 1) / strides_spatial_shape[i])
   SAME_UPPER or SAME_LOWER: output_spatial_shape[i] = ceil(input_spatial_shape[i] / strides_spatial_shape[i])
   ```
   And pad shape will be following if `SAME_UPPER` or `SAME_LOWER`:
   ```
   pad_shape[i] = (output_spatial_shape[i] - 1) * strides_spatial_shape[i] + kernel_spatial_shape[i] - input_spatial_shape[i]
   ```
  
  The output of each pooling window is divided by the number of elements (exclude pad when attribute count_include_pad is zero).
  
  Input and output scales and zero points are used to convert the output to a new quantization range.
  Output = Dequantize(Input) -> AveragePool on fp32 data -> Quantize(output)

### <a name="com.microsoft.QLinearReduceMean"></a><a name="com.microsoft.qlinearreducemean">**com.microsoft.QLinearReduceMean**</a>

  Computes the mean of the low-precision input tensor's element along the provided axes.
  The resulting tensor has the same rank as the input if keepdims equal 1. If keepdims equal 0,
  then the resulting tensor have the reduced dimension pruned. The above behavior is similar to numpy,
  with the exception that numpy default keepdims to False instead of True.
  Input and Output scales and zero points are used to requantize the output in a new range.
  This helps to improve accuracy as after ReduceMean operation the range of the output is expected to decrease.

  QLinearSoftmax computes the normalized exponential values for the given input:
  Softmax(input, axis) = Exp(input) / ReduceSum(Exp(input), axis=axis, keepdims=1)
  The input does not need to explicitly be a 2D vector. The "axis" attribute
  indicates the dimension along which QLinearSoftmax will be performed for onnx v.13+.
  or the dimension coerced to NxD Matrix for onnx v.12-.
  The output tensor has the same shape.

### <a name="com.microsoft.QOrderedAttention"></a><a name="com.microsoft.qorderedattention">**com.microsoft.QOrderedAttention**</a>

  Quantized version of simplified Multi-Head Self Attention(using int8 with specific matrix Layout).
  Multi-Head Self Attention that can be either unidirectional (like GPT-2) or bidirectional (like BERT).
  The mask_index input is optional. Besides raw attention mask with shape (batch_size, past_sequence_length + sequence_length)
  or (batch_size, sequence_length, past_sequence_length + sequence_length) with value 0 for masked and 1 otherwise,
  we also support other two formats: When input has right-side padding, mask_index is one dimension with shape (batch_size),
  where value of each element is the end position, or valid length of actual sequence excluding padding. When input has
  left-side padding, mask_index has shape (2 * batch_size), where the values are the exclusive end positions followed by
  the inclusive start positions. When unidirectional is 1, and each token only attend to previous tokens. For GPT-2, both past
  and present state are optional. Present state could appear in output even when past state is not in input.
  Current version does not support past/present, extra_add and qkv_hidden_sizes.
  TODO: Support them if needed in the future.

  Quantize (Int8) MatMul with order. Implement Y = alpha * A * B + bias + beta * C. Matrix A, B, C, Y are all int8 matrix.
  Two type of order combination supported:
    *) When order_B is ORDER_COL, order_A must be ORDER_ROW.
           bias is vector of {#cols of Y} of float32, C should be batch 1/batch_A. B could be of batch 1 or batch_A.
           Note B is reorder to ORDER_COL, or Transposed. Not Transposed first and then Reordered here.
    *) When order_B is specify ORDER_COL4_4R2_8C or ORDER_COL32_2R_4R4, orderA must be ORDER_COL32.
           MatMul will be implemented using alpha(A * B) + beta * C => Y.
           bias is not supported here. B in fact is transposed first then reordered into ORDER_COL4_4R2_8C or ORDER_COL32_2R_4R4 here.
  order_Y and order_C will be same as order_A.
  Support per column quantized weight, ie, scale_B is 1-D vector of size [#cols of matrix B].

### <a name="com.microsoft.QuantizeLinear"></a><a name="com.microsoft.quantizelinear">**com.microsoft.QuantizeLinear**</a>

  The linear quantization operator. It consumes a full precision data, a scale, a zero point to compute the low precision / quantized tensor.
  The quantization formula is y = saturate ((x / y_scale) + y_zero_point).For saturation, it saturates to [0, 255] if it's uint8, or [-128, 127] if it's int8.
  For (x / y_scale), it's rounding to nearest ties to even. Refer to https://en.wikipedia.org/wiki/Rounding for details.
  Scale and zero point must have same shape. They must be either scalar (per tensor) or 1-D tensor (per 'axis').

### <a name="com.microsoft.ReduceSumInteger"></a><a name="com.microsoft.reducesuminteger">**com.microsoft.ReduceSumInteger**</a>

  Computes the sum of the low-precision input tensor's element along the provided axes.
  The resulting tensor has the same rank as the input if keepdims equal 1. If keepdims equal 0,
  then the resulting tensor have the reduced dimension pruned. The above behavior is similar to numpy,
  with the exception that numpy default keepdims to False instead of True.

### <a name="com.microsoft.Tokenizer"></a><a name="com.microsoft.tokenizer">**com.microsoft.Tokenizer**</a>

  Tokenizer divides each string in X into a vector of strings along the last axis. Allowed input shapes are [C] and [N, C].
    If the maximum number of tokens found per input string is D, the output shape would be [N, C, D] when input shape is [N, C].
    Similarly, if input shape is [C] then the output should be [C, D]. Tokenizer has two different operation modes.
    The first mode is selected when "tokenexp" is not set and "separators" is set. If "tokenexp" is set and "separators" is not set,
    the second mode will be used. The first mode breaks each input string into tokens by matching and removing separators.
    "separators" is a list of strings which are regular expressions. "tokenexp" is a single regular expression.
    Let's assume "separators" is [" "] and consider an example.
    If input is
    ["Hello World", "I love computer science !"] whose shape is [2],
    then the output would be
   [["Hello", "World", padvalue, padvalue, padvalue],
   ["I", "love", "computer", "science", "!"]]
   whose shape is [2, 5] because you can find at most 5 tokens per input string.
   Note that the input at most can have two axes, so 3-D and higher dimension are not supported.
   If "separators" contains a single empty string, the Tokenizer will enter into character tokenezation mode. This means all strings
   will be broken part into individual characters.
   For each input string, the second mode searches matches of "tokenexp" and each match will be a token in Y.
   The matching of "tokenexp" is conducted greedily (i.e., a match should be as long as possible).
   This operator searches for the first match starting from the beginning of the considered string,
   and then launches another search starting from the first remained character after the first matched token.
   If no match found, this operator will remove the first character from the remained string and do another search.
   This procedure will be repeated until reaching the end of the considered string.
    Let's consider another example to illustrate the effect of setting "mark" to true.
    If input is ["Hello", "World"],
    then the corresponding output would be [0x02, "Hello", "World", 0x03].
    This implies that if mark is true, [C]/[N, C] - input's output shape becomes [C, D+2]/[N, C, D+2].
  If tokenizer removes the entire content of [C]-input, it will produce [[]].
  I.e. the output shape should be [C][0] or [N][C][0] if input shape was [N][C].
  If the tokenizer receives empty input of [0] then the output is [0] if empty input
  of [N, 0] then [N, 0].

  Returns the upper or lower triangular part of a 2-D matrix, or batches of 2-D matrices. If the attribute "upper" is set to true,
        the upper triangular matrix is retained. Lower triangular matrix is retained otherwise. Default value for upper is true.
        Trilu takes one input tensor of shape [*, N, M], where * is zero or more batch dimensions. The upper triangular part consists
        of the elements on and above the given diagonal (k). The lower triangular part consists of elements on and below the diagonal.
        All other elements in the matrix are set to zero.

  QEmbedLayerNormalization is the quantized fusion of embedding layer in BERT model, with optional mask processing.
  The embedding layer takes input_ids (word IDs) and segment_ids (sentence IDs) to look up word_embedding, position_embedding,
  and segment_emedding; the embeddings are added then applied layer normalization using gamma and beta tensors. The input_ids
  and segment_ids remain int32. All embeddings, gamma, and beta tensors are converted to int8/uint8. The last input mask is optional.
  If mask is provided, mask index (that is position of first 0 in mask, or number of words will be calculated.
