This operator can conduct the optimization of multiple tensor variables.\n\n    Let\'s define the behavior of this operator. As you can imagine, ADAGRAD requires\n    some parameters:\n\n     - The initial learning-rate \"R\".\n     - The update count \"T\". That is, the number of training iterations conducted.\n     - A L2-norm regularization coefficient \"norm_coefficient\".\n     - A learning-rate decay factor \"decay_factor\".\n     - A small constant \"epsilon\" to avoid dividing-by-zero.\n\n    At each ADAGRAD iteration, the optimized tensors are moved along a direction\n    computed based on their estimated gradient and accumulated squared gradient. Assume\n    that only a single tensor \"X\" is updated by this operator. We need the value of \"X\",\n    its gradient \"G\", and its accumulated squared gradient \"H\". Therefore, variables in\n    this operator\'s input list are sequentially \"R\", \"T\", \"X\", \"G\", and \"H\". Other\n    parameters are given as attributes because they are usually constants. Also, the\n    corresponding output tensors are the new value of \"X\" (called \"X_new\"), and then\n    the new accumulated squared gradient (called \"H_new\"). Those outputs are computed\n    from the given inputs following the pseudo code below.\n\n    Let \"+\", \"-\", \"*\", and \"/\" are all element-wise arithmetic operations with\n    numpy-style broadcasting support. The pseudo code to compute those outputs is:\n\n      // Compute a scalar learning-rate factor. At the first update of X, T is generally\n      // 0 (0-based update index) or 1 (1-based update index).\n      r = R / (1 + T * decay_factor);\n\n      // Add gradient of 0.5 * norm_coefficient * ||X||_2^2, where ||X||_2 is the 2-norm.\n      G_regularized = norm_coefficient * X + G;\n\n      // Compute new accumulated squared gradient.\n      H_new = H + G_regularized * G_regularized;\n\n      // Compute the adaptive part of per-coordinate learning rate. Note that Sqrt(...)\n      // computes element-wise square-root.\n      H_adaptive = Sqrt(H_new) + epsilon\n\n      // Compute the new value of \"X\".\n      X_new = X - r * G_regularized / H_adaptive;\n\n    If one assign this operators to optimize multiple inputs, for example, \"X_1\" and \"X_2\", the same\n    pseudo code may be extended to handle all tensors jointly. More specifically, we can view \"X\" as a\n    concatenation of \"X_1\" and \"X_2\" (of course, their gradient and accumulate gradient should\n    be concatenated too) and then just reuse the entire pseudo code.\n\n    Note that ADAGRAD was first proposed in http://jmlr.org/papers/volume12/duchi11a/duchi11a.pdf.\n    In that reference paper, this operator is a special case of the Figure 1\'s composite mirror\n    descent update.\n"

The \'to\' argument must be one of the data types specified\nin the \'DataType\' enum field in the TensorProto message.\n\nCasting from string tensor in plain (e.g., \"3.14\" and \"1000\") and scientific numeric representations\n(e.g., \"1e-5\" and \"1E8\") to float types is supported. For example, converting string \"100.5\" to an integer may\nresult 100. There are some string literals reserved for special floating-point values;\n\"+INF\" (and \"INF\"), \"-INF\", and \"NaN\" are positive infinity, negative infinity, and not-a-number, respectively.\nAny string which can exactly match \"+INF\" in a case-insensitive way would be mapped to positive infinite. Similarly,\nthis case-insensitive rule is applied to \"INF\" and \"NaN\". When casting from numeric tensors\nto string tensors, plain floating-point representation (such as \"314.15926\") would be used.\nConverting non-numerical-literal string such as \"Hello World!\" is an undefined behavior. Cases\nof converting string representing floating-point arithmetic value, such as \"2.718\", to INT is an undefined behavior.\n\nConversion from a numerical type to any numerical type is always allowed.\nUser must be aware of precision loss and value change caused by range difference between two types.\nFor example, a 64-bit float 3.1415926459 may be round to a 32-bit float 3.141592. Similarly, converting\nan integer 36 to Boolean may produce 1 because we truncate bits which can\'t be stored in the targeted type.\n"

  doc_string: "\nGradient operator computes the partial derivatives of a specific tensor w.r.t.\nsome other tensors. This operator is widely used in gradient-based training\nalgorithms. To illustrate its use, let\'s consider a computation graph,\n\n```\nX -----.\n       |\n       v\nW --> Conv --> H --> Gemm --> Y\n                      ^\n                      |\n                      Z\n```\n\n, where W and Z are trainable tensors. Note that operators\' attributes are\nomitted for the sake of simplicity. Let dY/dW (dY/dZ) be the gradient of\nY with respect to W (Z). The user can compute gradient by inserting Gradient\noperator to form another graph shown below.\n\n```\nW --> Conv --> H --> Gemm --> Y\n|      ^              ^\n|      |              |\n|      X              Z\n|      |              |\n|      |   .----------\'\n|      |   |  (W/Z/X is the 1st/2nd/3rd input of Gradient as shown in\n|      |   |   \"xs\" followed by \"zs\")\n|      v   v\n\'---> Gradient(xs=[\"W\", \"Z\"], zs=[\"X\"], y=\"Y\")\n       |   |\n       |   \'-----------------------------------> dY/dW (1st output of Gradient)\n       |\n       \'---------------------------------------> dY/dZ (2nd output of Gradient)\n```\n\nBy definition, the tensor \"y\" is a function of independent variables in \"xs\"\nand \"zs\". Since we only compute the gradient of \"y\" w.r.t. the differentiable\nvariables in \"xs\", this Gradient only outputs dY/dW and dY/dZ. Note that \"H\"\ncannot appear in \"xs\" and \"zs\". The reason is that \"H\" can be determined by\ntensors \"W\" and \"X\" and therefore \"H\" is not an independent variable.\n\nAll outputs are optional. If needed, for example, user can assign an empty\nstring to the 1st output name of that Gradient to skip the generation of dY/dW.\nNote that the concept of optional outputs can also be found in ONNX\'s RNN, GRU,\nand LSTM.\n\nGradient operator can compute derivative against intermediate tensors. For\nexample, the gradient of Y with respect to H can be done via\n\n```\nW --> Conv --> H --> Gemm --> Y\n       ^       |      ^\n       |       |      |\n       X       |      Z\n       .-------\'      |\n       |   .----------\'\n       |   | (H/Z is the 1st/2nd input of Gradient as shown in \"xs\")\n       v   v\n      Gradient(xs=[\"H\", \"Z\"], y=\"Y\")\n       |   |\n       |   \'-----------------------------------> dY/dH (1st output of Gradient)\n       |\n       \'---------------------------------------> dY/dZ (2nd output of Gradient)\n```\n\nIt is possible to represent high-order differentiation using Gradient operators.\nFor example, given the following linear model:\n\n```\nW --> Gemm --> Y --> Loss --> O\n       ^              ^\n       |              |\n       X              L\n```\n\nTo compute the 2nd order derivative of O with respect to W (denoted by\nd^2O/dW^2), one can do\n\n```\nW --> Gemm --> Y --> Loss --> O\n|      ^              ^\n|      |              |\n|      X .------------L\n|      | |            |\n|      | |            v\n+------+-+> Gradient(xs=[\"X\", \"W\"], zs=[\"L\"], y=\"O\") ---> dO/dX (1st output of Gradient)\n|      | |    |\n|      | |    \'---> dO/dW (2nd output of Gradient)\n|      v v\n\'---> Gradient(xs=[\"X\", \"W\"], zs=[\"L\"], y=\"dO/dW\") ---> d(dO/dW)dX (1st output of\n       |                                                  Gradient)\n       |\n       |\n       \'---> d^2O/dW^2 (2nd output of Gradient)\n```\n\nThe tensors named in attributes \"xs\", \"zs\", and \"y\" define the differentiated\ncomputation graph, and the inputs to Gradient node define the values at\nwhich the gradient is computed. We can feed different tensors to the identified\ngraph. For example, one can compute the gradient of Y with respect to H at\na specific value of H, H_1, by providing that value as an input to the Gradient\nnode.\n\n```\nW --> Conv --> H --> Gemm --> Y\n       ^              ^\n       |              |\n       X              Z\n\n          Z_1 (2nd input of Gradient)\n           |\n           v\nH_1 --> Gradient(xs=[\"H\", \"Z\"], y=\"Y\") ---> dY/dH when H = H_1 and Y = Y_1.\n           |\n           \'------------------------------> dY/dZ (2nd output of Gradient)\n```\n\nWhen the inputs of Gradient are the tensors named in \"xs\" and \"zs\", the\ncomputation can be optimized. More specifically, intermediate variables in\nforward pass can be reused if the gradient is computed via reverse-mode\nauto-differentiation.\n\n"

The loop operation node\n   supplies the input value of the input variable for the first iteration, and\n   returns the output value of the output variable produced by the final\n   iteration.\n3) Scan_output variables are used to implicitly concatenate values computed across\n   all the iterations. In the above example, the value of user_defined_val computed\n   over all iterations are concatenated and returned as the value of user_defined_vals\n   after the loop.\n4) Values created in the body cannot be accessed in the enclosing scope,\n   except using the mechanism described above.\n\nNote that the semantics of this op support \"diagonal\" or \"wavefront\" execution.\n(See Step 3 here for an example:\nhttps://devblogs.nvidia.com/optimizing-recurrent-neural-networks-cudnn-5/).\nFrontends should emit multi-layer RNNs as a series of While operators (with\ntime being the inner looping dimension), with each successive layer consuming\nthe scan_outputs from the previous layer, possibly going through several\npoint-wise operators (e.g. dropout, residual connections, linear layer).\n\nThe input/output of subgraph (produced by loop node) matching is based on order instead of name. The implementation will figure out the names based on this order.\n"

Set the attribute \"mode\" to\n    \"nesterov\" if Nesterov\'s momentum is desired. Otherwise, set the attribute \"model\" to\n    \"standard\" to use standard momentum. Computation details are described subsequently.\n\n    Let \"+\", \"-\", \"*\", and \"/\" are all element-wise operations with numpy-style broadcasting.\n\n    Pseudo code for SG with standard momentum:\n\n      // Add gradient of 0.5 * norm_coefficient * ||X||^2, where ||X|| is the sum of squared\n      // values of all elements in X.\n      G_regularized = norm_coefficient * X + G\n\n      // In the first training iteration, beta should always be 1.\n      beta_adjusted = T > 0 ? beta : 1\n\n      // Compute the current momentum based on previous momentum and the current gradient.\n      V_new = alpha * V + beta_adjusted * G_regularized\n\n      // Update X.\n      X_new = X - R * V_new\n\n    Pseudo code for SG with Nesterov\'s momentum:\n\n      // Add gradient of 0.5 * norm_coefficient * ||X||^2, where ||X|| is the sum of squared\n      // values of all elements in X.\n      G_regularized = norm_coefficient * X + G;\n\n      // In the first training iteration, beta should always be 1.\n      beta_adjusted = T > 0 ? beta : 1\n\n      // Compute the current momentum based on previous momentum and the current gradient.\n      V_new = alpha * V + beta_adjusted * G_regularized;\n\n      // Compute final update direction and then update X.\n      X_new = X - R * (G_regularized + alpha * V_new)\n\n    If one assign this operators to optimize multiple inputs, for example, \"X_1\" and \"X_2\". The same\n    pseudo code would be extended to handle all tensors jointly. More specifically, we can view \"X\" as a\n    concatenation of \"X_1\" and \"X_2\" (of course, their gradient and accumulate gradient should\n    be concatenated too) and then our pseudo code becomes applicable.\n"

  doc_string: "\nScan can be used to iterate over one or more scan_input tensors,\nconstructing zero or more scan_output tensors. It combines ideas from general recurrences,\nfunctional programming constructs such as scan, fold, map, and zip and is intended to enable\ngeneralizations of RNN-like constructs for sequence-to-sequence processing.\nOther tensors (referred to as state_variables here) can be used to carry a state\nwhen iterating from one element to another (similar to hidden-state in RNNs, also referred\nto as loop-carried dependences in the context of loops).\nMany common usages involve a single scan_input tensor (where functionality\nsimilar to scan, fold and map can be obtained). When more than one scan_input is used,\na behavior similar to zip is obtained.\n\nThe attribute body must be a graph, specifying the computation to be performed in\nevery iteration. It takes as input the current values of the state_variables and\nthe current iterated element of the scan_inputs. It must return the (updated) values\nof the state_variables and zero or more scan_output_element tensors. The values of the\nscan_output_element tensors are concatenated over all the iterations to produce the\nscan_output values of the scan construct (similar to the concatenated intermediate\nhidden-state values of RNN-like constructs). All the output tensors (state_variables as\nwell as scan_output_element tensors) are required to have the same shape in each iteration\nof the loop (a restriction imposed to enable efficient memory allocation).\n\nNote that the iterated element passed to the body subgraph does not have a sequence\naxis. It will have a rank one less than the rank of the corresponding scan_input.\n\nThe scan operation returns the final values of the state_variables as well as the\nscan_outputs.\n\nThe optional attribute scan_input_directions specifies the direction (forward or backward)\nfor each scan input. If this attribute is omitted, all sequences are scanned in the forward\ndirection. A bidirectional scan may be performed by specifying the same tensor input twice\nin the scan_inputs, once with a forward direction, and once with a backward direction.\n\nThe scan_output of the operation is produced by concatenating the scan_output_element\nvalues produced by the body in each iteration.  The optional attribute scan_output_directions\nspecifies the direction in which scan_output is constructed (by appending or prepending the\nscan_output_element to scan_output in each iteration) for each scan_output. If this attribute\nis omitted, the scan_output_element is appended to the scan_output in each iteration.\n\nThe optional attribute scan_input_axes specifies the axis to be scanned for each scan_input.\nIf omitted, every scan_input will be scanned in axis 0. For example, if axis 0 is the\nbatch axis and axis 1 is the time axis (to be scanned), specify an axis value of 1.\nNote that scanning a non-zero axis may be less efficient than scanning axis zero.\n\nThe optional attribute scan_output_axes specifies the axis along which the scan_outputs\nare accumulated for each scan_output. For example, if axis 1 is the time axis (to be\nscanned) for both inputs and outputs, specify a scan_input axis and scan_output axis\nvalue of 1.\n\nNote that because of the ONNX restriction that only the last parameter of an operator can\nbe variadic, the initial-states and scan-inputs are listed together as one input parameter.\nSimilarly, the final-states and scan-outputs are listed together as one output parameter.\nThe attribute num_scan_inputs indicates the number M of scan-inputs.\n\nThe behavior of\n\n    Scan <\n        num_scan_inputs = m,\n        body = loop-body,\n        scan_input_axes = [axis_1, ..., axis_m]\n    > (init_1, ..., init_n, scan_1, ..., scan_m)\n\nis equivalent to the following pseudo-code:\n\n    // scan_i.shape[axis_i] denotes the (max) sequence-length of scan_i\n    // scan_i.shape[axis_i] is required to be equal to scan_j.shape[axis_j] for all i,j.\n    sequence_length = scan_1.shape[axis_1];\n\n    // initialize state-variables\n    st_1 = init_1; ... st_n = init_n;\n    // initialize scan-output variables: [] denotes an empty tensor\n    scan_out_1 = []; ...; scan_out_k = [];\n    // identify number of iterations:\n\n    // execute loop\n    for (int t = 0; t < sequence_length; ++t) {\n        // generate the scan-input elements: the notation T<axis=k>[t] indicates the sub-tensor\n        // of rank one less than T obtained by indexing T at position t along axis k.\n        si_1 = scan_1<axis=axis_1>[t];\n        ... ;\n        si_m = scan_m<axis=axis_m>[t];\n        // execute loop-body\n        st_1, ..., st_n, so_1, ..., so_k = loop-body(st_1, ..., st_n, si_1, ..., si_m)\n        // accumulate the scan-output elements\n        scan_out_1 = Concat<axis=0>(scan_out_1, so_1); ... ; scan_out_k = Concat<axis=0>(scan_out_k, so_k);\n    }\n\n    return st_1, ..., st_n, scan_out_1, ..., scan_out_k;\n\n*Sample usage: Encoding RNN using a Scan*\n\nThe following example shows how a simple RNN over an input tensor %X, with weight tensor %Wi,\nrecurrence weight tensor %Ri, bias tensors %Wbi and %Rbi, and initial hidden-state %H_0 can\nbe encoded as a ScanLoop.

  doc_string: "\nScatterND takes three inputs `data` tensor of rank r >= 1, `indices` tensor of rank q >= 1,\nand `updates` tensor of rank q + r - indices.shape[-1] - 1. The output of the operation\nis produced by creating a copy of the input `data`, and then updating its value to values\nspecified by `updates` at specific index positions specified by `indices`. Its output shape\nis the same as the shape of `data`. Note that `indices` should not have duplicate entries.\nThat is, two or more `updates` for the same index-location is not supported.\n\n`indices` is an integer tensor. Let k denote indices.shape[-1], the last dimension in the shape of `indices`.\n `indices` is treated as a (q-1)-dimensional tensor of k-tuples, where each k-tuple is a partial-index into `data`.\nHence, k can be a value at most the rank of `data`. When k equals rank(data), each update entry specifies an\nupdate to a single element of the tensor. When k is less than rank(data) each update entry specifies an\nupdate to a slice of the tensor.\n\n`updates` is treated as a (q-1)-dimensional tensor of replacement-slice-values. Thus, the\nfirst (q-1) dimensions of updates.shape must match the first (q-1) dimensions of indices.shape.\nThe remaining dimensions of `updates` correspond to the dimensions of the\nreplacement-slice-values. Each replacement-slice-value is a (r-k) dimensional tensor,\ncorresponding to the trailing (r-k) dimensions of `data`.  Thus, the shape of `updates`\nmust equal indices.shape[0:q-1] ++ data.shape[k:r-1], where ++ denotes the concatenation\nof shapes.\n\nThe `output` is calculated via the following equation:\n\n    output = np.copy(data)\n    update_indices = indices.shape[:-1]\n    for idx in np.ndindex(update_indices):\n        output[indices[idx]] = updates[idx]\n\nThe order of iteration in the above loop is not specified.\nIn particular, indices should not have duplicate entries: that is, if idx1 != idx2, then indices[idx1] != indices[idx2].\nThis ensures that the output value does not depend on the iteration order.\n\nThis operator is the inverse of GatherND.\n\nExample 1:\n```\n  data    = [1, 2, 3, 4, 5, 6, 7, 8]\n  indices = [[4], [3], [1], [7]]\n  updates = [9, 10, 11, 12]\n  output  = [1, 11, 3, 10, 9, 6, 7, 12]\n```\n\nExample 2:\n```\n  data    = [[[1, 2, 3, 4], [5, 6, 7, 8], [8, 7, 6, 5], [4, 3, 2, 1]],\n             [[1, 2, 3, 4], [5, 6, 7, 8], [8, 7, 6, 5], [4, 3, 2, 1]],\n             [[8, 7, 6, 5], [4, 3, 2, 1], [1, 2, 3, 4], [5, 6, 7, 8]],\n             [[8, 7, 6, 5], [4, 3, 2, 1], [1, 2, 3, 4], [5, 6, 7, 8]]]\n  indices = [[0], [2]]\n  updates = [[[5, 5, 5, 5], [6, 6, 6, 6], [7, 7, 7, 7], [8, 8, 8, 8]],\n             [[1, 1, 1, 1], [2, 2, 2, 2], [3, 3, 3, 3], [4, 4, 4, 4]]]\n  output  = [[[5, 5, 5, 5], [6, 6, 6, 6], [7, 7, 7, 7], [8, 8, 8, 8]],\n             [[1, 2, 3, 4], [5, 6, 7, 8], [8, 7, 6, 5], [4, 3, 2, 1]],\n             [[1, 1, 1, 1], [2, 2, 2, 2], [3, 3, 3, 3], [4, 4, 4, 4]],\n             [[8, 7, 6, 5], [4, 3, 2, 1], [1, 2, 3, 4], [5, 6, 7, 8]]]\n```\n"

  doc_string: "\nThis transform extracts n-grams from the input sequence and save them as a vector. Input can\nbe either a 1-D or 2-D tensor. For 1-D input, output is the n-gram representation of that input.\nFor 2-D input, the output is also a  2-D tensor whose i-th row is the n-gram representation of the i-th input row.\nMore specifically, if input shape is [C], the corresponding output shape would be [max(ngram_indexes) + 1].\nIf input shape is [N, C], this operator produces a [N, max(ngram_indexes) + 1]-tensor.\n\nIn contrast to standard n-gram extraction, here, the indexes of extracting an n-gram from the original\nsequence are not necessarily consecutive numbers. The discontinuity between indexes are controlled by the number of skips.\nIf the number of skips is 2, we should skip two tokens when scanning through the original sequence.\nLet\'s consider an example. Assume that input sequence is [94, 17, 36, 12, 28] and the number of skips is 2.\nThe associated 2-grams are [94, 12] and [17, 28] respectively indexed by [0, 3] and [1, 4].\nIf the number of skips becomes 0, the 2-grams generated are [94, 17], [17, 36], [36, 12], [12, 28]\nindexed by [0, 1], [1, 2], [2, 3], [3, 4], respectively.\n\nThe output vector (denoted by Y) stores the count of each n-gram;\nY[ngram_indexes[i]] indicates the times that the i-th n-gram is found. The attribute ngram_indexes is used to determine the mapping\nbetween index i and the corresponding n-gram\'s output coordinate. If pool_int64s is [94, 17, 17, 36], ngram_indexes is [1, 0],\nngram_counts=[0, 0], then the Y[0] (first element in Y) and Y[1] (second element in Y) are the counts of [17, 36] and [94, 17],\nrespectively. An n-gram which cannot be found in pool_strings/pool_int64s should be ignored and has no effect on the output.\nNote that we may consider all skips up to S when generating the n-grams.\n\nThe examples used above are true if mode is \"TF\". If mode is \"IDF\", all the counts larger than 1 would be truncated to 1 and\nthe i-th element in weights would be used to scale (by multiplication) the count of the i-th n-gram in pool. If mode is \"TFIDF\",\nthis operator first computes the counts of all n-grams and then scale them by the associated values in the weights attribute.\n\nOnly one of pool_strings and pool_int64s can be set. If pool_int64s is set, the input should be an integer tensor.\nIf pool_strings is set, the input must be a string tensor.\n"
