DESCRIPTION

Overview: This module prepares a NaiveBayesModel for visualization. Many calculations that are needed by the visualization are done here, before the model is visualized.Detailed Description: This module determines which of the input features of the training data are the best predictors of the output. This is done by performing predictions on the training data and leaving out one input feature each time. Data structures to hold values for the pie charts in NaiveBayesVis are also created here.Data Type Restrictions: noneData Handling: The data structures used to display pie charts in NaiveBayesVis are created by this module. These structures are stored in Naive Bayes Model. The number of pie charts is proportional to the number of discrete values in the inputs of the training data set.Scalability: This module will perform NxM predictions, where N is the number of inputs and M is the number of training examples.

INPUTS

Name	Description	Example
nbModel	Read org.seasr.meandre.support.components.prediction.naivebayes.NaiveBayesModel as input.

OUTPUTS

Name	Description	Example
nbModel	Ouptut org.seasr.meandre.support.components.prediction.naivebayes.NaiveBayesModel after calculation.
error	This port is used to output any unhandled errors encountered during the execution of this component

PROPERTIES

Name	Description	Default value
_debug_level	Controls the verbosity of debug messages printed by the component during execution. Possible values are: off, severe, warning, info, config, fine, finer, finest, all Append ',mirror' to any of the values above to mirror that output to the server logs.	info
_ignore_errors	Set to 'true' to ignore all unhandled exceptions and prevent the flow from being terminated. Setting this property to 'false' will result in the flow being terminated in the event an unhandled exception is thrown during the execution of this component	false
