This kernel is based on a static kernel matrix that is read from a file. Instances must have a single nominal attribute (excluding the class). This attribute must be the first attribute in the file and its values are used to reference rows/columns in the kernel matrix. The second attribute must be the class attribute.
Valid options are:
-D Enables debugging output (if available) to be printed. (default: off)
-no-checks Turns off all checks - use with caution! (default: checks on)
-M <file name> The file name of the file that holds the kernel matrix. (default: kernelMatrix.matrix)

方法详细资料
-
copy
Return a shallow copy of this kernel -
globalInfo
Returns a string describing the kernel- 指定者:
globalInfo
在类中Kernel
- 返回:
- a description suitable for displaying in the explorer/experimenter gui
-
listOptions
Returns an enumeration describing the available options.- 指定者:
listOptions
在接口中OptionHandler
- 覆盖:
listOptions
在类中Kernel
- 返回:
- an enumeration of all the available options.
-
setOptions
Parses a given list of options. Valid options are:-D Enables debugging output (if available) to be printed. (default: off)
-no-checks Turns off all checks - use with caution! (default: checks on)
-M <file name> The file name of the file that holds the kernel matrix. (default: kernelMatrix.matrix)
- 指定者:
setOptions
在接口中OptionHandler
- 覆盖:
setOptions
在类中Kernel
- 参数:
options
- the list of options as an array of strings- 抛出:
Exception
- if an option is not supported
-
getOptions
Gets the current settings of the Kernel.- 指定者:
getOptions
在接口中OptionHandler
- 覆盖:
getOptions
在类中Kernel
- 返回:
- an array of strings suitable for passing to setOptions
-
eval
从类复制的说明:Kernel
Computes the result of the kernel function for two instances. If id1 == -1, eval use inst1 instead of an instance in the dataset. -
getCapabilities
Returns the Capabilities of this kernel.- 指定者:
getCapabilities
在接口中CapabilitiesHandler
- 覆盖:
getCapabilities
在类中Kernel
- 返回:
- the capabilities of this object

-
setKernelMatrixFile
Sets the file holding the kernel matrix- 参数:
value
- the exponent value
-
getKernelMatrixFile
Gets the file containing the kernel matrix.- 返回:
- the exponent value
-
kernelMatrixFileTipText
Returns the tip text for this property- 返回:
- tip text for this property suitable for displaying in the explorer/experimenter gui
-
toString
returns a string representation for the Kernel -
clean
public void clean()Frees the memory used by the kernel. (Useful with kernels which use cache.) This function is called when the training is done. i.e. after that, eval will be called with id1 == -1. -
numEvals
public int numEvals()Returns the number of kernel evaluation performed. -
numCacheHits
public int numCacheHits()Returns the number of dot product cache hits.- 指定者:
numCacheHits
在类中Kernel
- 返回:
- the number of dot product cache hits, or -1 if not supported by this kernel.
-
getRevision
Returns the revision string.- 指定者:
getRevision
在接口中RevisionHandler
- 覆盖:
getRevision
在类中Kernel
- 返回:
- the revision
