Explanation about TaskCardΒΆ
TaskCard delineates the phases in transforming the source dataset into a model-input, and specifies the metrics for evaluation of model-output.
- Attributes:
loader: specifies the source address and the loading operator that can access that source and transform it into a unitxt multistream.
preprocess_steps: list of unitxt operators to process the data source into a model-input.
task: specifies the fields (of the already (pre)processed instance) making the inputs, the fields making the outputs, and the metrics to be used for evaluating the model output.
templates: format strings to be applied on the input fields (specified by the task) and the output fields. The template also carries the instructions and the list of postprocessing steps, to be applied to the model output.
Explanation about FilterByConditionΒΆ
Filters a stream, yielding only instances in which the values in required fields follow the required condition operator.
Raises an error if a required field name is missing from the input instance.
- Args:
values (Dict[str, Any]): Field names and respective Values that instances must match according the condition, to be included in the output. condition: the name of the desired condition operator between the specified (sub) fieldβs value and the provided constant value. Supported conditions are (βgtβ, βgeβ, βltβ, βleβ, βneβ, βeqβ, βinβ,βnot inβ) error_on_filtered_all (bool, optional): If True, raises an error if all instances are filtered out. Defaults to True.
- Examples:
FilterByCondition(values = {βaβ:4}, condition = βgtβ) will yield only instances where field βaβ contains a value > 4 FilterByCondition(values = {βaβ:4}, condition = βleβ) will yield only instances where βaβ<=4 FilterByCondition(values = {βaβ:[4,8]}, condition = βinβ) will yield only instances where βaβ is 4 or 8 FilterByCondition(values = {βaβ:[4,8]}, condition = βnot inβ) will yield only instances where βaβ different from 4 or 8 FilterByCondition(values = {βa/bβ:[4,8]}, condition = βnot inβ) will yield only instances where βaβ is
a dict in which key βbβ is mapped to a value that is neither 4 nor 8
- FilterByCondition(values = {βa[2]β:4}, condition = βleβ) will yield only instances where βaβ is a list whose 3-rd
element is <= 4
Explanation about ApplyΒΆ
A class used to apply a python function and store the result in a field.
- Args:
function (str): name of function. to_field (str): the field to store the result additional arguments are field names passed to the function
Examples: Store in field βbβ the uppercase string of the value in field βaβ Apply(βaβ, function=str.upper, to_field=βbβ)
Dump the json representation of field βtβ and store back in the same field. Apply(βtβ, function=json.dumps, to_field=βtβ)
Set the time in a field βbβ. Apply(function=time.time, to_field=βbβ)
Explanation about RemoveFieldsΒΆ
Remove specified fields from each instance in a stream.
- Args:
fields (List[str]): The fields to remove from each instance.
Explanation about CopyFieldsΒΆ
Copies values from specified fields to specified fields.
- Args (of parent class):
field_to_field (Union[List[List], Dict[str, str]]): A list of lists, where each sublist contains the source field and the destination field, or a dictionary mapping source fields to destination fields.
- Examples:
An input instance {βaβ: 2, βbβ: 3}, when processed by CopyField(field_to_field={βaβ: βbβ} would yield {βaβ: 2, βbβ: 2}, and when processed by CopyField(field_to_field={βaβ: βcβ} would yield {βaβ: 2, βbβ: 3, βcβ: 2}
with field names containing / , we can also copy inside the field: CopyFields(field_to_field={βa/0β: βaβ}) would process instance {βaβ: [1, 3]} into {βaβ: 1}
Explanation about ListFieldValuesΒΆ
Concatenates values of multiple fields into a list, and assigns it to a new field.
Explanation about RenameFieldsΒΆ
Renames fields.
Move value from one field to another, potentially, if field name contains a /, from one branch into another. Remove the from field, potentially part of it in case of / in from_field.
- Examples:
RenameFields(field_to_field={βbβ: βcβ}) will change inputs [{βaβ: 1, βbβ: 2}, {βaβ: 2, βbβ: 3}] to [{βaβ: 1, βcβ: 2}, {βaβ: 2, βcβ: 3}]
RenameFields(field_to_field={βbβ: βc/dβ}) will change inputs [{βaβ: 1, βbβ: 2}, {βaβ: 2, βbβ: 3}] to [{βaβ: 1, βcβ: {βdβ: 2}}, {βaβ: 2, βcβ: {βdβ: 3}}]
RenameFields(field_to_field={βbβ: βb/dβ}) will change inputs [{βaβ: 1, βbβ: 2}, {βaβ: 2, βbβ: 3}] to [{βaβ: 1, βbβ: {βdβ: 2}}, {βaβ: 2, βbβ: {βdβ: 3}}]
RenameFields(field_to_field={βb/c/eβ: βb/dβ}) will change inputs [{βaβ: 1, βbβ: {βcβ: {βeβ: 2, βfβ: 20}}}] to [{βaβ: 1, βbβ: {βcβ: {βfβ: 20}, βdβ: 2}}]
Explanation about SplitRandomMixΒΆ
Splits a multistream into new streams (splits), whose names, source input stream, and amount of instances, are specified by arg βmixβ.
The keys of arg βmixβ, are the names of the new streams, the values are of the form: βname-of-source-stream[percentage-of-source-stream]β Each input instance, of any input stream, is selected exactly once for inclusion in any of the output streams.
Examples: When processing a multistream made of two streams whose names are βtrainβ and βtestβ, by SplitRandomMix(mix = { βtrainβ: βtrain[99%]β, βvalidationβ: βtrain[1%]β, βtestβ: βtestβ }) the output is a multistream, whose three streams are named βtrainβ, βvalidationβ, and βtestβ. Output stream βtrainβ is made of randomly selected 99% of the instances of input stream βtrainβ, output stream βvalidationβ is made of the remaining 1% instances of input βtrainβ, and output stream βtestβ is made of the whole of input stream βtestβ.
When processing the above input multistream by SplitRandomMix(mix = { βtrainβ: βtrain[50%]+test[0.1]β, βvalidationβ: βtrain[50%]+test[0.2]β, βtestβ: βtest[0.7]β }) the output is a multistream, whose three streams are named βtrainβ, βvalidationβ, and βtestβ. Output stream βtrainβ is made of randomly selected 50% of the instances of input stream βtrainβ + randomly selected 0.1 (i.e., 10%) of the instances of input stream βtestβ. Output stream βvalidationβ is made of the remaining 50% instances of input βtrainβ+ randomly selected 0.2 (i.e., 20%) of the original instances of input βtestβ, that were not selected for output βtrainβ, and output stream βtestβ is made of the remaining instances of input βtestβ.
