Building Artificial Neural Network Using WEKA

theagroupofbi — Thu, 26 Nov 2009 15:32:13 +0000

The building process of Artificial Neural Networks (ANNs) in WEKA is using Multilayer Perceptron (MLP) function. MLP is a classifier that uses backpropagation to classify instances. The network can be built by hand, created by an algorithm or both. This study exploring one of WEKA features to build an ANN.

Keywords : Artificial Neural Network, WEKA, Multilayer Perceptron.

Entropy

theagroupofbi — Thu, 26 Nov 2009 15:22:07 +0000

Entropy at a given node t:

(NOTE: p( j | t) is the relative frequency of class j at node t).

Measures homogeneity of a node.
Maximum (log n_c) when records are equally distributed among all classes implying least information
Minimum (0.0) when all records belong to one class, implying most information
Entropy based computations are similar to the GINI index computations

Nowadays the business environment in organization is ever changing, and it is becoming more and more complex. Organizations, both private and public, feel increasing pressures that force them to respond quickly to changing conditions and to be innovative in the way they operate. Such activities require organizations to be agile and make frequent and quick strategic. The manager is should use the right decision in the right time so the manager should use the right vendor of its business intelligence applications. This paper will compare some business intelligence application both open source and commercial tools.

Exploring Business Intelligence Tools

theagroupofbi — Thu, 26 Nov 2009 10:08:38 +0000

In this assignment, we try to find interesting development for Business Intelligence tools from intelligententerprise.com.

There are many tools for Business Technologies today. The most interesting are they that using the latest kind of technology. The more modern technology used by the tools, the better use it can be. Not only the business that shapes technology, but the technologies can shapes business, for the need of keeping competitive advantages. One article we got from the website is 4 Technologies That Are Reshaping Business Intelligence, written by Doug Henschen, published in August 2009. The full article can be viewed in http://www.intelligententerprise.com/showArticle.jhtml?articleID=219500509.

Based on the article, the next-generation BI is being formed by predictive analytics, real-time monitoring, in-memory processing, and SaaS.

College Scheduler

Background

When we get into new semester, we will pick new classes and will get new schedule, and sometimes it is confusing to arrange the best schedule for us. We need to do it manually and usually takes a lot of time and not impossible to made mistakes. College scheduler can help you for that.

Description

College scheduler is a intelligent application that can help student to arrange their schedule with their classes. It will generate automatically all possible schedule you can get, and the good news is, you can add your preferences such as preferred time (day or night, what day, what time), preferred lecture, course-mate and lecturer, etc as consideration for arranging your schedule.

Features

This software has special features instead of the standard function of other online academic system-like softwares. The features are:

Can be integrated with regular online academic system such as FRS-Online in ITS or can be another web-based academic information system.
Automatic scheduling to give the student information about set of courses that he can choose.
The student can add his preferences to get the course of the most suitable and comfortable for him.
Expandable features (on desktop version), include download marks of the student.
Report generator to make printable version document. (Only on desktop version)

Benefit

With this software, we can get some benefit:

Omitting conflicted courses.
Reducing workload of college advisor (dosen wali).
Giving the students best suggestion of college schedule set.
Monitoring available class (if integrated with online academic system)
Avoid procrastination that can make late graduation.

Versions

This software is built in several versions, based on the system. College scheduler is available for:

Windows
Linux
mobile phone (java)
web-based

For Windows and Linux

When we install this software, it’s just like another software we installed before in our PC. After installation process finish, we are ready to set up our profile. This kind has more features than any other version because PC has lots of sources like faster processor, bigger memory, abundant storage, wider display and so on.

For Mobile Phone

In this version, size of the software is decreasing into a very tiny size compare to PC’s version but still not losing its main function i.e. scheduling. Users still get some main function such as automatic scheduling based on our preferences and other features. But the capacity to handle a lot of classes is not available.

Web-based

This version doesn’t require us to install. We just visit the website, create an account, fill the profile form, then we can start to use the software. All you need is a computer with internet connection, compatible browser, and list of your available classes. Then you will see how this software can arrange classes for you.

Procedure to use this software is all similar with all versions. First we just need to install the package (if in PC version or Mobile Phone version) or visit the website. Then we have to fill up the profile form. After that, we can start input available class and their schedule (time, day, lecture, classroom number, etc). After all requirements is fulfilled, then we can let the smart system to arrange possibility schedule for that classes. It will give us all possible option class based on our preferences, ex maximum credit, preferred time (day, night), preferred lecture, preferred lecturer, etc. After that, we can let the system run for us.

The practical work objective is to understand OLAP and how we use it on SQL Server 2008. This is done by observing the presentation given by practical work assistants and try to explore OLAP in SQL Server 2008 or formally known as SQL Server Analysis Services (SSAS) in its documentation and also have limited covers on SQL Server Integration Services (SSIS). The result of this practical work is the students know better about the practice of using the software for business intelligence related analysis.
