PrincipalComponentAnalysis Methods |
The PrincipalComponentAnalysis type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | Adjust(Double, Boolean) | Obsolete.
Adjusts a data matrix, centering and standardizing its values
using the already computed column's means and standard deviations.
|
| Adjust(Double, Boolean) | Obsolete.
Adjusts a data matrix, centering and standardizing its values
using the already computed column's means and standard deviations.
|
 | Compute | Obsolete.
Computes the Principal Component Analysis algorithm.
|
| CreateComponents |
Creates additional information about principal components.
(Inherited from BasePrincipalComponentAnalysis.) |
| 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.) |
 | FromCorrelationMatrix |
Constructs a new Principal Component Analysis from a Correlation matrix.
|
| FromCovarianceMatrix |
Constructs a new Principal Component Analysis from a Covariance matrix.
|
| FromGramMatrix |
Constructs a new Principal Component Analysis from a Kernel (Gram) matrix.
|
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetNumberOfComponents |
Returns the minimal number of principal components
required to represent a given percentile of the data.
(Inherited from BasePrincipalComponentAnalysis.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| Learn |
Learns a model that can map the given inputs to the desired outputs.
|
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Reduce |
Reduces the dimensionality of a given matrix x
to the given number of dimensions.
|
| Revert(Double) | Obsolete.
Reverts a set of projected data into it's original form. Complete reverse
transformation is only possible if all components are present, and, if the
data has been standardized, the original standard deviation and means of
the original matrix are known.
|
| Revert(Double) |
Reverts a set of projected data into it's original form. Complete reverse
transformation is only possible if all components are present, and, if the
data has been standardized, the original standard deviation and means of
the original matrix are known.
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Transform(TInput) |
Applies the transformation to a set of input vectors,
producing an associated set of output vectors.
(Inherited from MultipleTransformBaseTInput, TOutput.) |
| Transform(Double) | Obsolete.
Obsolete.
(Inherited from BasePrincipalComponentAnalysis.) |
| Transform(Double) |
Applies the transformation to an input, producing an associated output.
(Inherited from BasePrincipalComponentAnalysis.) |
| Transform(Double, Double) |
Projects a given matrix into principal component space.
(Overrides MultipleTransformBaseTInput, TOutputTransform(TInput, TOutput).) |
| Transform(Double, Int32) | Obsolete.
Projects a given matrix into principal component space.
(Inherited from BasePrincipalComponentAnalysis.) |
| Transform(Double, Double) |
Applies the transformation to an input, producing an associated output.
(Inherited from BasePrincipalComponentAnalysis.) |
| Transform(Double, Int32) | Obsolete.
Projects a given matrix into principal component space.
(Inherited from BasePrincipalComponentAnalysis.) |
| Transform(Double, Int32) | Obsolete.
Projects a given matrix into principal component space.
(Inherited from BasePrincipalComponentAnalysis.) |
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.
