Abstract

A system and method for preprocessing input data to a support vector machine (SVM). The SVM is a system model having parameters that define the representation of the system being modeled, and operates in two modes: run-time and training. A data preprocessor preprocesses received data in accordance with predetermined preprocessing parameters, and outputs preprocessed data. The data preprocessor includes an input buffer for receiving and storing the input data. The input data may be on different time scales. A time merge device determines a desired time scale and reconciles the input data so that all of the input data are placed on the desired time scale. An output device outputs the reconciled data from the time merge device as preprocessed data. The reconciled data may be input to the SVM in training mode to train the SVM, and/or in run-time mode to generate control parameters and/or predictive output information.

apply a predetermined algorithm to the input data prior to said performing said time merging.

80. The memory medium of claim 79, wherein each piece of data has associated therewith a time value corresponding to the time the input data was generated.

81. The memory medium of claim 79, wherein said program instructions are further executable to:

select said predetermined algorithm from a group of available algorithms.

82. The memory medium of claim 68, wherein said program instructions are further executable to:

apply a predetermined algorithm to the reconciled time merged data prior to outputting said reconciled time merged data.

83. The memory medium of claim 82, wherein said program instructions are further executable to:

select said predetermined algorithm from a group of available algorithms.

84. The memory medium of claim 68, wherein the input data comprise a plurality of variables, each of the variables comprising an input variable with an associated set of data wherein each of said variables comprises an input to said input buffer;

and

wherein each of at least a subset of said variables comprises a corresponding one of the inputs to the support vector machine.

85. The memory medium of claim 84, wherein said program instructions are further executable to:

receive reconciled data associated with a select one of said input variables; and

introduce a predetermined mount of delay to said reconciled data and output a delayed input variable and associated set of delayed reconciled input data.

86. The memory medium of claim 85, wherein said predetermined amount of delay is a function of an external variable, wherein said program instructions are further executable to:

vary said predetermined amount of delay as a function of said external variable.

87. The memory medium of claim 85, wherein said program instructions are further executable to:

learn said predetermined delay as a function of training parameters generated by a system modeled by the support vector machine.

88. The memory medium of claim 68, wherein said program instructions are further executable to present a graphical user interface (GUI), wherein said GUI is operable to receive user input specifying one or more data manipulation and/or reconciliation operations to be performed on said input data.

89. The memory medium of claim 88, wherein said GUI is further operable to display said input data prior to and after performing said manipulation and/or reconciliation operations on said input data.

90. The memory medium of claim 88, wherein said GUI is further operable to receive user input specifying a portion of said input data for said data manipulation and/or reconciliation operations.
