  description: "Spectrograms are a standard way of representing audio information as a series of\nslices of frequency information, one slice for each window of time. By joining\nthese together into a sequence, they form a distinctive fingerprint of the sound\nover time.\n\nThis op expects to receive audio data as an input, stored as floats in the range\n-1 to 1, together with a window width in samples, and a stride specifying how\nfar to move the window between slices. From this it generates a three\ndimensional output. The lowest dimension has an amplitude value for each\nfrequency during that time slice. The next dimension is time, with successive\nfrequency slices. The final dimension is for the channels in the input, so a\nstereo audio input would have two here for example.\n\nThis means the layout when converted and saved as an image is rotated 90 degrees\nclockwise from a typical spectrogram. Time is descending down the Y axis, and\nthe frequency decreases from left to right.\n\nEach value in the result represents the square root of the sum of the real and\nimaginary parts of an FFT on the current window of samples. In this way, the\nlowest dimension represents the power of each frequency in the current window,\nand adjacent windows are concatenated in the next dimension.\n\nTo get a more intuitive and visual look at what this operation does, you can run\ntensorflow/examples/wav_to_spectrogram to read in an audio file and save out the\nresulting spectrogram as a PNG image."

  description: "The `input` tensor has shape `[batch, in_height, in_width, depth]` and the\n`filter` tensor has shape `[filter_height, filter_width, depth]`, i.e., each\ninput channel is processed independently of the others with its own structuring\nfunction. The `output` tensor has shape\n`[batch, out_height, out_width, depth]`. The spatial dimensions of the output\ntensor depend on the `padding` algorithm. We currently only support the default\n\"NHWC\" `data_format`.\n\nIn detail, the grayscale morphological 2-D dilation is the max-sum correlation\n(for consistency with `conv2d`, we use unmirrored filters):\n\n    output[b, y, x, c] =\n       max_{dy, dx} input[b,\n                          strides[1] * y + rates[1] * dy,\n                          strides[2] * x + rates[2] * dx,\n                          c] +\n                    filter[dy, dx, c]\n\nMax-pooling is a special case when the filter has size equal to the pooling\nkernel size and contains all zeros.\n\nNote on duality: The dilation of `input` by the `filter` is equal to the\nnegation of the erosion of `-input` by the reflected `filter`."

  summary: "Performs fractional max pooling on the input."
  description: "Fractional max pooling is slightly different than regular max pooling.  In\nregular max pooling, you downsize an input set by taking the maximum value of\nsmaller N x N subsections of the set (often 2x2), and try to reduce the set by\na factor of N, where N is an integer.  Fractional max pooling, as you might\nexpect from the word \"fractional\", means that the overall reduction ratio N\ndoes not have to be an integer.\n\nThe sizes of the pooling regions are generated randomly but are fairly uniform.\nFor example, let\'s look at the height dimension, and the constraints on the\nlist of rows that will be pool boundaries.\n\nFirst we define the following:\n\n1.  input_row_length : the number of rows from the input set\n2.  output_row_length : which will be smaller than the input\n3.  alpha = input_row_length / output_row_length : our reduction ratio\n4.  K = floor(alpha)\n5.  row_pooling_sequence : this is the result list of pool boundary rows\n\nThen, row_pooling_sequence should satisfy:\n\n1.  a[0] = 0 : the first value of the sequence is 0\n2.  a[end] = input_row_length : the last value of the sequence is the size\n3.  K <= (a[i+1] - a[i]) <= K+1 : all intervals are K or K+1 size\n4.  length(row_pooling_sequence) = output_row_length+1\n\nFor more details on fractional max pooling, see this paper:\n[Benjamin Graham, Fractional Max-Pooling](http://arxiv.org/abs/1412.6071)"

For float\ninput, the values are normalized one image at a time to fit in the range\n`[0, 255]`.  `uint8` values are unchanged.  The op uses two different\nnormalization algorithms:\n\n*  If the input values are all positive, they are rescaled so the largest one\n   is 255.\n\n*  If any input value is negative, the values are shifted so input value 0.0\n   is at 127.  They are then rescaled so that either the smallest value is 0,\n   or the largest one is 255.\n\nThe `tag` argument is a scalar `Tensor` of type `string`.  It is used to\nbuild the `tag` of the summary values:\n\n*  If `max_images` is 1, the summary value tag is \'*tag*/image\'.\n*  If `max_images` is greater than 1, the summary value tags are\n   generated sequentially as \'*tag*/image/0\', \'*tag*/image/1\', etc.\n\nThe `bad_color` argument is the color to use in the generated images for\nnon-finite input values.  It is a `unit8` 1-D tensor of length `channels`.\nEach element must be in the range `[0, 255]` (It represents the value of a\npixel in the output image).  Non-finite values in the input tensor are\nreplaced by this tensor in the output image.  The default value is the color\nred."

  description: "This operation computes the inverse of an index permutation. It takes a 1-D\ninteger tensor `x`, which represents the indices of a zero-based array, and\nswaps each value with its index position. In other words, for an output tensor\n`y` and an input tensor `x`, this operation computes the following:\n\n`y[x[i]] = i for i in [0, 1, ..., len(x) - 1]`\n\nThe values must include 0. There can be no duplicate values or negative values.\n\nFor example:\n\n```\n# tensor `x` is [3, 4, 0, 2, 1]\ninvert_permutation(x) ==> [2, 4, 3, 0, 1]\n```"

  summary: "Quantizes then dequantizes a tensor."
  description: "This op simulates the precision loss from the quantized forward pass by:\n1. Quantizing the tensor to fixed point numbers, which should match the target\n   quantization method when it is used in inference.\n2. Dequantizing it back to floating point numbers for the following ops, most\n   likely matmul.\n\nThere are different ways to quantize. This version does not use the full range\nof the output type, choosing to elide the lowest possible value for symmetry\n(e.g., output range is -127 to 127, not -128 to 127 for signed 8 bit\nquantization), so that 0.0 maps to 0.\n\nTo perform this op, we first find the range of values in our tensor. The range\nwe use is always centered on 0, so we find m such that\n\n1. m = max(abs(input_min), abs(input_max)) if range_given is true,\n2. m = max(abs(min_elem(input)), abs(max_elem(input))) otherwise.\n\nOur input tensor range is then [-m, m].\n\nNext, we choose our fixed-point quantization buckets, [min_fixed, max_fixed].\nIf signed_input is true, this is\n\n  [min_fixed, max_fixed ] =\n      [-(1 << (num_bits - 1) - 1), (1 << (num_bits - 1)) - 1].\n\nOtherwise, if signed_input is false, the fixed-point range is\n\n  [min_fixed, max_fixed] = [0, (1 << num_bits) - 1].\n\nFrom this we compute our scaling factor, s:\n\n  s = (max_fixed - min_fixed) / (2 * m).\n\nNow we can quantize and dequantize the elements of our tensor.  An element e\nis transformed into e\':\n\n  e\' = (e * s).round_to_nearest() / s.\n\nNote that we have a different number of buckets in the signed vs. unsigned\ncases.  For example, if num_bits == 8, we get 254 buckets in the signed case\nvs. 255 in the unsigned case.\n\nFor example, suppose num_bits = 8 and m = 1.  Then\n\n  [min_fixed, max_fixed] = [-127, 127], and\n  s = (127 + 127) / 2 = 127.\n\nGiven the vector {-1, -0.5, 0, 0.3}, this is quantized to\n{-127, -63, 0, 38}, and dequantized to {-1, -63.0/127, 0, 38.0/127}."

  description: "actual distribution of the values to maximize the usage of the lower bit depth\nand adjusting the output min and max ranges accordingly.\n\n[input_min, input_max] are scalar floats that specify the range for the float\ninterpretation of the \'input\' data. For example, if input_min is -1.0f and\ninput_max is 1.0f, and we are dealing with quint16 quantized data, then a 0\nvalue in the 16-bit data should be interpreted as -1.0f, and a 65535 means 1.0f.\n\nThis operator tries to squeeze as much precision as possible into an output with\na lower bit depth by calculating the actual min and max values found in the\ndata. For example, maybe that quint16 input has no values lower than 16,384 and\nnone higher than 49,152. That means only half the range is actually needed, all\nthe float interpretations are between -0.5f and 0.5f, so if we want to compress\nthe data into a quint8 output, we can use that range rather than the theoretical\n-1.0f to 1.0f that is suggested by the input min and max.\n\nIn practice, this is most useful for taking output from operations like\nQuantizedMatMul that can produce higher bit-depth outputs than their inputs and\nmay have large potential output ranges, but in practice have a distribution of\ninput values that only uses a small fraction of the possible range. By feeding\nthat output into this operator, we can reduce it from 32 bits down to 8 with\nminimal loss of accuracy."

  summary: "Quantize the \'input\' tensor of type float to \'output\' tensor of type \'T\'."
  description: "[min_range, max_range] are scalar floats that specify the range for\nthe \'input\' data. The \'mode\' attribute controls exactly which calculations are\nused to convert the float values to their quantized equivalents.\n\nIn \'MIN_COMBINED\' mode, each value of the tensor will undergo the following:\n\n```\nout[i] = (in[i] - min_range) * range(T) / (max_range - min_range)\nif T == qint8, out[i] -= (range(T) + 1) / 2.0\n```\nhere `range(T) = numeric_limits<T>::max() - numeric_limits<T>::min()`\n\n*MIN_COMBINED Mode Example*\n\nAssume the input is type float and has a possible range of [0.0, 6.0] and the\noutput type is quint8 ([0, 255]). The min_range and max_range values should be\nspecified as 0.0 and 6.0. Quantizing from float to quint8 will multiply each\nvalue of the input by 255/6 and cast to quint8.\n\nIf the output type was qint8 ([-128, 127]), the operation will additionally\nsubtract each value by 128 prior to casting, so that the range of values aligns\nwith the range of qint8.\n\nIf the mode is \'MIN_FIRST\', then this approach is used:\n\n```\nnumber_of_steps = 1 << (# of bits in T)\nrange_adjust = number_of_steps / (number_of_steps - 1)\nrange = (range_max - range_min) * range_adjust\nrange_scale = number_of_steps / range\nquantized = round(input * range_scale) - round(range_min * range_scale) +\n  numeric_limits<T>::min()\nquantized = max(quantized, numeric_limits<T>::min())\nquantized = min(quantized, numeric_limits<T>::max())\n```\n\nThe biggest difference between this and MIN_COMBINED is that the minimum range\nis rounded first, before it\'s subtracted from the rounded value. With\nMIN_COMBINED, a small bias is introduced where repeated iterations of quantizing\nand dequantizing will introduce a larger and larger error.\n\nOne thing to watch out for is that the operator may choose to adjust the\nrequested minimum and maximum values slightly during the quantization process,\nso you should always use the output ports as the range for further calculations.\nFor example, if the requested minimum and maximum values are close to equal,\nthey will be separated by a small epsilon value to prevent ill-formed quantized\nbuffers from being created. Otherwise, you can end up with buffers where all the\nquantized values map to the same float value, which causes problems for\noperations that have to perform further calculations on them."

This operator is the inverse of the @{tf.gather_nd} operator which\nextracts values or slices from a given tensor.\n\n**WARNING**: The order in which updates are applied is nondeterministic, so the\noutput will be nondeterministic if `indices` contains duplicates.\n\n`indices` is an integer tensor containing indices into a new tensor of shape\n`shape`.  The last dimension of `indices` can be at most the rank of `shape`:\n\n    indices.shape[-1] <= shape.rank\n\nThe last dimension of `indices` corresponds to indices into elements\n(if `indices.shape[-1] = shape.rank`) or slices\n(if `indices.shape[-1] < shape.rank`) along dimension `indices.shape[-1]` of\n`shape`.  `updates` is a tensor with shape\n\n    indices.shape[:-1] + shape[indices.shape[-1]:]\n\nThe simplest form of scatter is to insert individual elements in a tensor by\nindex.

  summary: "Return a strided slice from `input`."
  description: "Note, most python users will want to use the Python `Tensor.__getitem__`\nor `Variable.__getitem__` rather than this op directly.\n\nThe goal of this op is to produce a new tensor with a subset of\nthe elements from the `n` dimensional `input` tensor. The subset is chosen using\na sequence of `m` sparse range specifications encoded into the arguments\nof this function. Note, in some cases\n`m` could be equal to `n`, but this need not be the case. Each\nrange specification entry can be one of the following:\n\n- An ellipsis (...). Ellipses are used to imply zero or more\n  dimensions of full-dimension selection and are produced using\n  `ellipsis_mask`. For example, `foo[...]` is the identity slice.\n\n- A new axis. This is used to insert a new shape=1 dimension and is\n  produced using `new_axis_mask`. For example, `foo[:, ...]` where\n  `foo` is shape `(3, 4)` produces a `(1, 3, 4)` tensor.\n\n\n- A range `begin:end:stride`. This is used to specify how much to choose from\n  a given dimension. `stride` can be any integer but 0.  `begin` is an integer\n  which represents the index of the first value to select while `end` represents\n  the index of the last value to select. The number of values selected in each\n  dimension is `end - begin` if `stride > 0` and `begin - end` if `stride < 0`.\n  `begin` and `end` can be negative where `-1` is the last element, `-2` is\n  the second to last. `begin_mask` controls whether to replace the explicitly\n  given `begin` with an implicit effective value of `0` if `stride > 0` and\n  `-1` if `stride < 0`. `end_mask` is analogous but produces the number\n  required to create the largest open interval. For example, given a shape\n  `(3,)` tensor `foo[:]`, the effective `begin` and `end` are `0` and `3`. Do\n  not assume this is equivalent to `foo[0:-1]` which has an effective `begin`\n  and `end` of `0` and `2`. Another example is `foo[-2::-1]` which reverses the\n  first dimension of a tensor while dropping the last two (in the original\n  order elements). For example `foo = [1,2,3,4]; foo[-2::-1]` is `[4,3]`.\n\n- A single index. This is used to keep only elements that have a given\n  index. For example (`foo[2, :]` on a shape `(5,6)` tensor produces a\n  shape `(6,)` tensor. This is encoded in `begin` and `end` and\n  `shrink_axis_mask`.\n\nEach conceptual range specification is encoded in the op\'s argument. This\nencoding is best understand by considering a non-trivial example. In\nparticular,\n`foo[1, 2:4, None, ..., :-3:-1, :]` will be encoded as\n\n```\nbegin = [1, 2, x, x, 0, x] # x denotes don\'t care (usually 0)\nend = [2, 4, x, x, -3, x]\nstrides = [1, 1, x, x, -1, 1]\nbegin_mask = 1<<4 | 1 << 5 = 48\nend_mask = 1<<5 = 32\nellipsis_mask = 1<<3 = 8\nnew_axis_mask = 1<<2 4\nshrink_axis_mask = 1<<0\n```\n\nIn this case if `foo.shape` is (5, 5, 5, 5, 5, 5) the final shape of\nthe slice becomes (2, 1, 5, 5, 2, 5).\nLet us walk step by step through each argument specification.\n\n1.  The first argument in the example slice is turned into `begin = 1` and\n`end = begin + 1 = 2`. To disambiguate from the original spec `2:4` we\nalso set the appropriate bit in `shrink_axis_mask`.\n\n2. `2:4` is contributes 2, 4, 1 to begin, end, and stride. All masks have\nzero bits contributed.\n\n3. None is a synonym for `tf.newaxis`. This means insert a dimension of size 1\ndimension in the final shape. Dummy values are contributed to begin,\nend and stride, while the new_axis_mask bit is set.\n\n4. `...` grab the full ranges from as many dimensions as needed to\nfully specify a slice for every dimension of the input shape.\n\n5. `:-3:-1` shows the use of negative indices. A negative index `i` associated\nwith a dimension that has shape `s` is converted to a positive index\n`s + i`. So `-1` becomes `s-1` (i.e. the last element). This conversion\nis done internally so begin, end and strides receive x, -3, and -1.\nThe appropriate begin_mask bit is set to indicate the start range is the\nfull range (ignoring the x).\n\n6. `:` indicates that the entire contents of the corresponding dimension\nis selected. This is equivalent to `::` or `0::1`. begin, end, and strides\nreceive 0, 0, and 1, respectively. The appropriate bits in `begin_mask` and\n`end_mask` are also set.\n\n*Requirements*:\n  `0 != strides[i] for i in [0, m)`\n  `ellipsis_mask must be a power of two (only one ellipsis)`"

For example, when\nthe forward TensorArray is dynamically sized, writes to this TensorArray\nmay resize the object.  The gradient TensorArray is statically sized based\non the size of the forward TensorArray when this operation executes.\nFurthermore, the size of the forward TensorArray is frozen by this call.\nAs a result, the flow is used to ensure that the call to generate the gradient\nTensorArray only happens after all writes are executed.\n\nIn the case of dynamically sized TensorArrays, gradient computation should\nonly be performed on read operations that have themselves been chained via\nflow to occur only after all writes have executed. That way the final size\nof the forward TensorArray is known when this operation is called.\n\n**A note about the source attribute:**\n\nTensorArray gradient calls use an accumulator TensorArray object.  If\nmultiple gradients are calculated and run in the same session, the multiple\ngradient nodes may accidentally flow through the same accumulator TensorArray.\nThis double counts and generally breaks the TensorArray gradient flow.\n\nThe solution is to identify which gradient call this particular\nTensorArray gradient is being called in.  This is performed by identifying\na unique string (e.g. \"gradients\", \"gradients_1\", ...) from the input\ngradient Tensor\'s name.  This string is used as a suffix when creating\nthe TensorArray gradient object here (the attribute `source`).\n\nThe attribute `source` is added as a suffix to the forward TensorArray\'s\nname when performing the creation / lookup, so that each separate gradient\ncalculation gets its own TensorArray accumulator."
