3. ABSTRACT

Fostering conceptual and cognitive change.

Creating metaknowledge and exploring hidden
implications of a learner’s understanding.

‘‘So far as the laws of mathematics refer to
reality, they are not certain. And so far as they
are certain, they do not refer to reality.’’

4. INTRODUCTION
 Fuzzy
Cognitive Mapping(FCM) is a tool for
formalizing understandings of conceptual
and casual relationships.
 FCMs
in educational organization.
 FCM
combine the strength of cognitive
maps with fuzzy logic.

5. FUZZY LOGIC

Embeds human knowledge into working algorithms.

highly complex systems whose behaviors are not
well understood.

If-Then rules are the examples of structured
knowledge.

Important tool in generic decision making.

6. FUZZY SETS

Fuzzy Sets can represent the degree to which a
quality is possessed.

Fuzzy Sets (Simple Fuzzy Variables) have values in
the range of [0,1]

7. FUZZY COGNITIVE MAPS
•
Fuzzy logic is a system for representing
uncertainty, or possibility.
EXAMPLES OF FCMS:

8. FUZZY LOGIC SYSTEM

Fuzzification: transforming crisp values into
linguistic terms of fuzzy sets.

Inference mechanism: Interprets the values in the
input vector and, based on user-defined rules,
assigns values to the output vector. Usually based
on if-then rules.

De-Fuzzification: conversion of fuzzy output to
crisp

10. CONCEPT MAPPING

Graphical representations of a specified conceptual
domain.

Include some aspect of subjectivity.

Representation of the perceptions and beliefs of a
decision maker

Represent a form of distributed intelligence.
 structure activity
 save mental work
 avoid error.

14. CLASSIFICATION OF FUZZY INFERENCE
METHODS
Fuzzy cognitive mapping, Sahyadri college of engineering and management.

15. MAMDANI'S METHOD

Step 1: Evaluate the antecedent for each rule.

Step 2: Obtain each rule's conclusion.

Step 3: Aggregate conclusions.

Step 4: Defuzzification.

16. CAUSALITY AND FCMS

The relation between causes and effects

Fuzzy logic allows the representation of fuzzy concepts
and degree of causality.

FCMs are a tool for representing a dynamic process
and modeling the process in real-time.

FCMs is the temporal and causal nature.

17. ADVANTAGES
1.
FCMs capture more information in the
relationships between concepts.
2. FCMs are dynamic.
3. FCMs express hidden relationships.
4. FCMs are combinable.
5. FCMs are tunable.

18. CONCLUSION

Potential usefulness of fuzzy cognitive mapping
in educational organization settings.

Combining the capability of fuzzy logic to represent soft
knowledge domains with dynamic modeling.

Stimulates educational research to recognize the
unique applicability of fuzzy logic to our field.
