Introduction

Welcome readers! We hope you are doing well.

In today’s computing world, data visualisation and data mining are consistent and essential concepts for analysing large and multidimensional data.

If you want to know more about data miningyou can refer to our articles Data MiningTop 10 Common Data Mining Algorithms.

In this article, we will be dealing with Orange.

No, we are talking about the Orange Tool, open-source software for visualising the data.

 

In this article, we will be discussing different aspects of the Orange software, starting from scratch. This blog will help you enhance your understanding of the Orange tool for data mining.

So, without any further ado, let’s start the topic.

About Orange

Orange is an open-source data visualisation, data mining and machine learning software developed by the University of Ljubljana. It is used to develop and test the machine learning models and conduct exploratory data analysis and visualisation.

Usage of Orange

The uses of the Orange are shown below:

a) Interactive Data Visualisation:

Orange can be used as a data visualisation tool that helps us to uncover the hidden patterns of the data. The visualisation widgets of the data include the scatter plot for visualising correlations between pairs of attributes, box plot for displaying basic statistics and histogram or other model-specific visualisation like dendrogramsilhouette plot for analysing the result of clustering and tree visualisations for classification of the trees and forests.

b) Visual Programming

Orange can be used as a data mining tool for beginners and expert data scientists. The speciality of the Orange is that it is very simple and easy to use. No laborious coding is required for analysing the data. Thus, it makes it simpler for the interface used to simplify the complex data analytic pipelines.

Features of Orange

We have learned that Orange is a component-based visual programming software package.  

Let’s now explore some of the basic features of the Orange:

  • Canvas: It is the visual programming interface for Orange.
     
  • Widgets: The widgets are nothing but a GUI(Graphical User Interface) element that displays some information. Orange Widgets are building blocks of data analysis. It offers basic functionality such as reading datashowing data tablescomparing learning algorithms, visualising data elements etc.

    The different Orange widgets are shown below:

    • Data: widgets for Filedata input, filteringimputingattributes selectingsamplingedit domain etc.
       
    • Model: widgets for ConstantkNNSVMTreeRandom ForestLinear RegressionLogistic RegressionCurve FitNeural NetworkStacking etc.
       
    • Transform: widgets for Select ColumnsSelect RowsMerge DataTransposeAggregate ColumnsPreprocess etc.

    • Evaluate: widgets for Confusion MatrixROC AnalysisLift CurveTest LearnersPredictions.
       
    • Visualise: widgets for scatter plotDistributionslinear projection, mosaic display, sieve diagram etc.
       
    • Regression: widgets for Linear Regression LearnerMean LearnerRegression Tree ViewerRegression Tree Learner etc.
       
    • Unsupervised: widgets for Distance File, Save Distance FileMatrix TransformationInteraction GraphAttribute DistanceK-Means Clustering, Distance Map etc.
       
    • Associate: widgets for Association Rules, Item SetsAssociation Rules Filter etc.
       
    • Survival Analysis: widgets for As Survival Data, Cox regression, Cohorts.
       
    • Bioinformatics: widgets for Databases UpdateGenesMarker GenesCluster Analysis etc.

Orange Data Mining

In this section, we will be discussing how to use Orange as a data mining tool. 

The term Data Mining refers to analysing a large amount of information to discern trends and patterns.

The Orange core objects and Python modules incorporate numerous data mining tasks. The operating principle of Orange is to cover techniques and perspectives in data mining and machine learning.

Orange Widgets 

The basics of the Orange Widget have already been defined in the earlier section. Here we will only discuss how it will be used in data mining.

As we saw before, the Orange Widgets are nothing but an element of a GUI(Graphical User Interface) that displays some information. The widgets are regarded as data mining units. They incorporate different types of widgets for performing various tasks.
The widgets communicate with each other by tokens passed from the sender to the receiver through communication channels.

A sample workflow of the Orange widgets is shown below,

Orange Scripting

To access the Orange object, we need to write our components and design our test schemes through the script. Orange uses Python Script as a scripting language with a clear and powerful syntax and many additional libraries.
