Creates a new Grouping filter with equal group
proportions and default Group indicator column.
|
| Grouping(String) |
Creates a new Grouping filter.

Properties| Name | Description | |
|---|---|---|
 | Active |
Gets or sets whether this filter is active. An inactive
filter will repass the input table as output unchanged.
(Inherited from BaseFilterTOptions, TFilter.) |
| Columns |
Gets the collection of filter options.
(Inherited from BaseFilterTOptions, TFilter.) |
| GroupIndicatorColumnName |
Gets or sets the name of the indicator
column which will be used to distinguish
samples from either group.
|
| GroupIndices |
Gets or sets the group index labels.
|
| ItemInt32 |
Gets options associated with a given variable (data column).
(Inherited from BaseFilterTOptions, TFilter.) |
| ItemString |
Gets options associated with a given variable (data column).
(Inherited from BaseFilterTOptions, TFilter.) |
| Lock |
Gets or sets a value indicating whether the group labels
are locked and should not be randomly re-selected.
|
| NumberOfInputs |
Gets the number of inputs accepted by the model.
(Inherited from BaseFilterTOptions, TFilter.) |
| Proportion |
Gets or sets the two-group proportions.
|
| Token |
Gets or sets a cancellation token that can be used to
stop the learning algorithm while it is running.
(Inherited from BaseFilterTOptions, TFilter.) |
Methods| Name | Description | |
|---|---|---|
| Add |
Add a new column options definition to the collection.
(Inherited from BaseFilterTOptions, TFilter.) |
| Apply(DataTable) |
Applies the Filter to a DataTable.
(Inherited from BaseFilterTOptions, TFilter.) |
| Apply(DataTable, String) |
Applies the Filter to a DataTable.
(Inherited from BaseFilterTOptions, TFilter.) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetEnumerator |
Returns an enumerator that iterates through the collection.
(Inherited from BaseFilterTOptions, TFilter.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| OnAddingOptions |
Called when a new column options definition is being added.
Can be used to validate or modify these options beforehand.
(Inherited from BaseFilterTOptions, TFilter.) |
| ProcessFilter |
Processes the current filter.
(Overrides BaseFilterTOptions, TFilterProcessFilter(DataTable).) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Extension Methods| Name | Description | |
|---|---|---|
 | HasMethod |
Checks whether an object implements a method with the given name.
(Defined by ExtensionMethods.) |
| IsEqual |
Compares two objects for equality, performing an elementwise
comparison if the elements are vectors or matrices.
(Defined by Matrix.) |
| To(Type) | Overloaded.
Converts an object into another type, irrespective of whether
the conversion can be done at compile time or not. This can be
used to convert generic types to numeric types during runtime.
(Defined by ExtensionMethods.) |
| ToT | Overloaded.
Converts an object into another type, irrespective of whether
the conversion can be done at compile time or not. This can be
used to convert generic types to numeric types during runtime.
