# VectorDataDSValidation

## Brief Description

Vector data validation based on the fusion of features using Dempster-Shafer evidence theory framework.

## Long Description

This application validates or unvalidate the studied samples using the Dempster-Shafer theory.

## Parameters

- [param] -in <string> Input vector data to validate. Mandatory: True. Default Value: ""
- [param] -descmod <string> Fuzzy descriptors model (xml file). Mandatory: True. Default Value: ""
- [param] -belsup <string> Dempster Shafer study hypothesis to compute belief. Mandatory: True. Default Value: ""
- [param] -plasup <string> Dempster Shafer study hypothesis to compute plausibility. Mandatory: True. Default Value: ""
- [param] -cri <string> Dempster Shafer criterion (by default (belief+plausibility)/2). Mandatory: False. Default Value: "((Belief + Plausibility)/2.)"
- [param] -thd <float> Criterion threshold (default 0.5). Mandatory: False. Default Value: "0.5"
- [param] -out <string> Output VectorData containing only the validated samples. Mandatory: True. Default Value: ""
