3
Introduction
  • Learning
  • Factors Influencing Learning
  • Different Learning Systems
  • Limitations of These Learning Systems
  • One Solution
  • Adaptive Learning Systems

4
What are Adaptive Learning Systems ?
  • Consideration for the concept that
  • Each Individual is Different
  • Each Individual Learns Differently
  • Each Individual has Different Needs
  • Each Individual has Different Preferences
  • Address the fact that Coursework and Training
    should vary accordingly.

5
What are Adaptive Learning Systems ?
  • Adaptive learning systems adapt to the users
    automatically based on this concept to make
    learning more effective, increase user efficiency
    and satisfaction

6
Other Adaptive Learning Systems
  • Real Adaptive Intelligent Learning System (RAILS)
  • Adaptive Learning Intelligent System (ALIS)
  • Virtual Adaptive Learning Architecture (VALA)

7
What is Modality?
  • Definition
  • Types of Modality
  • Examples

8
Factors Influencing Learning
  • Age
  • Gender
  • Time of Day
  • Personal Preferences
  • Content of Learning Material
  • Motivation

9
Goal Of Our Research
  • To Develop a New Automated Adaptive
  • Content Delivery Training System,
  • that adapts and changes the modality of the
    presentation of course content,
  • based on an individual users learning factors

10
Fuzzy Logic Fuzzy Systems
  • A Quick Review
  • - Fuzzy Set Theory
  • - Membership Functions

11
System Operation
  • Operational Stages
  • Collection of Data from User
  • Building User Profile
  • Short Course
  • Evaluation / Assessment
  • Decision for Modality
  • Presentation of Instruction Material
  • Evaluation /Assessment
  • Repeat Steps 2,3,.. Or Quit Program
  • End of Instruction Material

12
Architecture of System
13
Fuzzy Neural Networks (FNN)
  • An Intelligent Hybrid System
  • Fuzzy Logic Neural Networks FNN
  • Why FNN?
  • Handles Uncertainties
  • Automatically Generates the Rule Base

14
Design Structure of the Fuzzy Neural Network
(FNN)
  • Three Main Stages in the operation of the FNN
  • Fuzzification
  • Inferencing Process
  • Defuzzification

15
Stage 1 in the FNN Fuzzification
  • Convert Crisp Input to Fuzzy Input using
    Membership Functions

16
Stage 2 in the FNN Inferencing Process
  • Using the Rule Base, Process the Inputs to Get
    Fuzzy Output

17
Stage 3 in the FNN Defuzzification
  • Convert the Fuzzy Output to Crisp Output

18
Internal Structure of the FNN
19
Implementation Details
  • Networked Laboratory with Nodes running,
  • Red Hat Linux
  • M S Windows XP
  • Software Development using,
  • M S PowerPoint
  • Visual Basic
  • C

20
Conclusions
  • Based on Fuzzy Logic Neural Networks,
  • our Adaptive Learning System,
  • Chooses an Appropriate Modality of Presentation
  • Offers a Choice to the User to Select Modality
  • Presents Instruction Material
  • Assesses User Learning
  • Improves the Learning Pace of User

21
Futurework
  • Integration of Effects of Behavioral
    Cognitive Skills of Users
  • Refinement Optimization of the FNN
  • Integration of Concepts from Kinesthetics
    Virtual Reality
  • Addition of System Scalability Features
