ONNX LabelEncoder operation

"Maps each element in the input tensor to another value.
" " The mapping is determined by the two parallel attributes, 'keys_' and" " 'values_' attribute.

" " Let's consider an example which maps a string tensor to an integer tensor." " Assume and 'keys_strings' is ["Amy", "Sally"], 'values_int64s' is [5, 6]," " and 'default_int64' is '-1'. The input ["Dori", "Amy", "Amy", "Sally"," " "Sally"] would be mapped to [-1, 5, 5, 6, 6].
" " Since this operator is an one-to-one mapping, its input and output shapes" " are the same. Notice that only one of 'keys_'/'values_' can be set.
" " For key look-up, bit-wise comparison is used so even a float NaN can be" " mapped to a value in 'values_' attribute.

`onnx.MaxUnpool` (ONNXMaxUnpoolOp)

ONNX MaxUnpool operation

"MaxUnpool essentially computes the partial inverse of the MaxPool op." " The input information to this op is typically the the output information from a MaxPool op. The first" " input tensor X is the tensor that needs to be unpooled, which is typically the pooled tensor (first output)" " from MaxPool. The second input tensor, I, contains the indices to the (locally maximal) elements corrsponding" " to the elements in the first input tensor X. Input tensor I is typically the second output of the MaxPool op." " The third (optional) input is a tensor that specifies the output size of the unpooling operation." "" "MaxUnpool is intended to do 'partial' inverse of the MaxPool op. 'Partial' because all the non-maximal" " values from the original input to MaxPool are set to zero in the output of the MaxUnpool op. Pooling" " the result of an unpooling operation should give back the original input to the unpooling op." "" "MaxUnpool can produce the same output size for several input sizes, which makes unpooling op ambiguous." " The third input argument, output_size, is meant to disambiguate the op and produce output tensor of" " known/predictable size." "" "In addition to the inputs, MaxUnpool takes three attributes, namely kernel_shape, strides, and pads," " which define the exact unpooling op. The attributes typically have the same values as the corrsponding" " pooling op that the unpooling op is trying to invert."

"The linear per-tensor/layer quantization operator. It consumes a high precision tensor, 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. 'y_zero_point' and 'y' must have same type."

Given an input tensor of" "shape [a_1, a_2, ..., a_n, r] and integer argument k, return two outputs:" " -Value tensor of shape [a_1, a_2, ..., a_{axis-1}, k, a_{axis+1}, ... a_n]" " which contains the values of the top k elements along the specified axis" " -Index tensor of shape [a_1, a_2, ..., a_{axis-1}, k, a_{axis+1}, ... a_n] which" " contains the indices of the top k elements (original indices from the input" " tensor)." "" "If "largest" is 1 (the default value) then the k largest elements are returned." "If "sorted" is 1 (the default value) then the resulting k elements will be sorted." "If "sorted" is 0, order of returned 'Values' and 'Indices' are undefined." "" "Given two equivalent values, this operator uses the indices along the axis as" " a tiebreaker. That is, the element with the lower index will appear first."
