1. Overview

Introduction

Bayonet System is a sytem that helps to construct a bayesian network. It can be used with or without prior experience data. It can use the data from the experience tables to construct the CPT. Either the GUI application or the network commands can be used to build a bayesian network.

This document will describe the features of Bayonet System and a tutorial to explain how to use the system to build a bayesian network.

Features

Some of the special features that Bayonet System offers include,

Based on Neural Network

Neural networks are used in the Bayonet System to represent conditional probabilities of many kind of variables including non-linear continuous variables.

Interface

Bayonet System provides GUI and network based interface.

Editor

Bayonet system offers the editor where you can create and modify nodes, links and their properties. It has three windows. The one on right side is a canvas for editing the bayesian network model. You can open multiple projects at a time and select the displayed tabs for setting current project. The left side window is the information panel that helps you modify the properties of the bayesian network objetcs. In this window, you can view the entire system, the projects and their objects. It is the provision for updating node and state properties, connecting to the database, updating CPT and CPA values. Tree and Tree Selector are the other functions available in this window. There is another window at the bottom which displays the macros and messages.

Multi-dimensional States

Bayonet System allows to have muti dimensional states.

Tree Selector

Bayonet System offers a special feature for selecting the best tree. You can select an algorithm and see animation of the trees one by one. You can watch the results and select the best tree given by the algorithm or select the tree you want.

Create Macro

While you are using the GUI you can also view the network based commands used and the resulting messages. You can save the macro which can be modifid further and used seperately.

Import / Export

The bayesian network generated by Bayonet System can be exported in XML file format. The system can also import files in the specified format to build the bayesian network.

Connectivity

The bayesian network generated by Bayonet System can be stored as a Hugin net file.
