Operator Schemas#
This file is automatically generated from the def files via this script. Do not modify directly and instead edit operator definitions.
For an operator input/output’s differentiability, it can be differentiable, non-differentiable, or undefined. If a variable’s differentiability is not specified, that variable has undefined differentiability.

ai.onnx.ml.CategoryMapper#
Converts strings to integers and vice versa.
Two sequences of equal length are used to map between integers and strings,
with strings and integers at the same index detailing the mapping.
Each operator converts either integers to strings or strings to integers, depending
on which default value attribute is provided. Only one default value attribute
should be defined.
If the string default value is set, it will convert integers to strings.
If the int default value is set, it will convert strings to integers.
Version#
This version of the operator has been available since version 1 of the ‘ai.onnx.ml’ operator set.

Type Constraints#
- T1 : tensor(string), tensor(int64)
- The input must be a tensor of strings or integers, either [N,C] or [C].
- T2 : tensor(string), tensor(int64)
- The output is a tensor of strings or integers. Its shape will be the same as the input shape.
ai.onnx.ml.DictVectorizer#
Uses an index mapping to convert a dictionary to an array.
Given a dictionary, each key is looked up in the vocabulary attribute corresponding to
the key type. The index into the vocabulary array at which the key is found is then
used to index the output 1-D tensor ‘Y’ and insert into it the value found in the dictionary ‘X’.
The key type of the input map must correspond to the element type of the defined vocabulary attribute.
Therefore, the output array will be equal in length to the index mapping vector parameter.
All keys in the input dictionary must be present in the index mapping vector.
For each item in the input dictionary, insert its value in the output array.
Any keys not present in the input dictionary, will be zero in the output array.
For example: if the string_vocabulary parameter is set to ["a", "c", "b", "z"],
then an input of {"a": 4, "c": 8} will produce an output of [4, 8, 0, 0].

- The output will be a tensor of the value type of the input map. It's shape will be [1,C], where C is the length of the input dictionary.
ai.onnx.ml.FeatureVectorizer#
Concatenates input tensors into one continuous output.

All inputs must be integers or floats, while the output will be all floating point values.
Version#
This version of the operator has been available since version 1 of the ‘ai.onnx.ml’ operator set.

ai.onnx.ml.Imputer#
Replaces inputs that equal one value with another, leaving all other elements alone.
This operator is typically used to replace missing values in situations where they have a canonical
representation, such as -1, 0, NaN, or some extreme value.
One and only one of imputed_value_floats or imputed_value_int64s should be defined – floats if the input tensor
holds floats, integers if the input tensor holds integers. The imputed values must all fit within the
width of the tensor element type. One and only one of the replaced_value_float or replaced_value_int64 should be defined,
which one depends on whether floats or integers are being processed.
The imputed_value attribute length can be 1 element, or it can have one element per input feature.
In other words, if the input tensor has the shape [*,F], then the length of the attribute array may be 1 or F. If it is 1, then it is broadcast along the last dimension and applied to each feature.
Version#
This version of the operator has been available since version 1 of the ‘ai.onnx.ml’ operator set.
Attributes#
- imputed_value_floats : list of floats
- Value(s) to change to
- imputed_value_int64s : list of ints
- Value(s) to change to.
- replaced_value_float : float (default is 0.0)
- A value that needs replacing.
- replaced_value_int64 : int (default is 0)
- A value that needs replacing.
Inputs#
- X : T

Outputs#
- Y : T

Type Constraints#
- T : tensor(float), tensor(double), tensor(int64), tensor(int32)
- The input type must be a tensor of a numeric type, either [N,C] or [C]. The output type will be of the same tensor type and shape.
ai.onnx.ml.LabelEncoder#
Maps each element in the input tensor to another value.
The mapping is determined by the two parallel attributes, ‘keys_’ and
‘values_’ attribute. The i-th value in the specified ‘keys_’ attribute
would be mapped to the i-th value in the specified ‘values_’ attribute. It
implies that input’s element type and the element type of the specified
‘keys_’ should be identical while the output type is identical to the
specified ‘values_’ attribute. If an input element can not be found in the
specified ‘keys_’ attribute, the ‘default_’ that matches the specified
‘values_’ attribute may be used as its output value.
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.

- T : tensor(float), tensor(double), tensor(int64), tensor(int32)
- The input type must be a tensor of a numeric type.
ai.onnx.ml.ZipMap#
Creates a map from the input and the attributes.
The values are provided by the input tensor, while the keys are specified by the attributes.
Must provide keys in either classlabels_strings or classlabels_int64s (but not both).
The columns of the tensor correspond one-by-one to the keys specified by the attributes. There must be as many columns as keys.
Version#
This version of the operator has been available since version 1 of the ‘ai.onnx.ml’ operator set.
Attributes#
- classlabels_int64s : list of ints
- The keys when using int keys.
One and only one of the 'classlabels_*' attributes must be defined. - classlabels_strings : list of strings
- The keys when using string keys.
One and only one of the 'classlabels_*' attributes must be defined.
Inputs#
- X : tensor(float)
- The input values
Outputs#
- Z : T
- The output map
Type Constraints#
- T : seq(map(string, float)), seq(map(int64, float))
- The output will be a sequence of string or integer maps to float.
