### What Is Fuzzy Inference Systems?

• A.

The process of formulating the mapping from a given input to an output using fuzzy logic

• B.

Changing the output value to match the input value to give it an equal balance

• C.

Having a larger output than the input

• D.

Having a smaller output than the input

A. The process of formulating the mapping from a given input to an output using fuzzy logic
Explanation
Fuzzy Inference Systems refer to the process of formulating the mapping from a given input to an output using fuzzy logic. Fuzzy logic allows for the representation of uncertainty and imprecision in data, enabling the system to handle vague and ambiguous information. By using fuzzy logic, the system can make decisions and provide outputs based on the degrees of membership to different categories or classes, rather than relying on strict binary logic. This approach is particularly useful in situations where there is incomplete or uncertain information, allowing for more flexible and nuanced decision-making.

### What Are The Two Types Of Fuzzy Inference Systems?

• A.

Model-Type and System-Type

• B.

Momfred-Type and Semigi-Type

• C.

Mamdani-Type and Sugeno-Type

• D.

Mihni-Type and Sujgani-Type

C. Mamdani-Type and Sugeno-Type
Explanation
The correct answer is Mamdani-Type and Sugeno-Type. These are the two types of fuzzy inference systems commonly used in fuzzy logic. The Mamdani-Type system uses fuzzy rules and linguistic variables to make decisions, while the Sugeno-Type system uses fuzzy rules and mathematical functions to make decisions. Both types are used in various applications such as control systems and decision-making processes.

### Where Has Fuzzy Inference Systems Been Implemented?

• A.

Wireless services, heat control, and printers.

• B.

Restrict power usage, telephone lines, and sort data.

• C.

• D.

Automatic control, decision analysis, and data classification.

D. Automatic control, decision analysis, and data classification.
Explanation
Fuzzy Inference Systems have been implemented in various applications such as automatic control, decision analysis, and data classification. These systems utilize fuzzy logic to handle uncertainty and imprecise information, allowing for more flexible and nuanced decision-making processes. In the context of automatic control, fuzzy inference systems can be used to regulate and optimize complex systems. In decision analysis, they can assist in making informed choices by considering multiple factors and their degrees of relevance. Additionally, in data classification, fuzzy inference systems can be used to categorize data based on its similarity to different classes.

### What Is Another Name For Fuzzy Inference Systems?

• A.

Fuzzy Expert System

• B.

Fuzzy Modelling

• C.

Fuzzy Logic Controller

• D.

All of the above

D. All of the above
Explanation
All of the given options are alternative names for fuzzy inference systems. A fuzzy inference system is a type of artificial intelligence that uses fuzzy logic to make decisions or draw conclusions based on imprecise or uncertain data. It can be referred to as a fuzzy expert system because it utilizes expert knowledge to make decisions. Fuzzy modelling is another name as it involves creating mathematical models using fuzzy logic. Fuzzy logic controller is another term as it refers to the use of fuzzy logic in controlling systems or processes. Therefore, all of the options are correct alternative names for fuzzy inference systems.

### Mamdani's Fuzzy Inference Method Was Designed To Attempt What?

• A.

Control any two combinations of any two products by synthesizing a set of linguistic control rules obtained from experienced human operations.

• B.

Control a television and remote combination by synthesizing a set of linguistic control rules obtained from experienced human operations.

• C.

Control a steam engine and a boiler combination by synthesizing a set of linguistic control rules obtained from experienced human operations.

• D.

Control an air craft and fuel level combination by synthesizing a set of linguistic control rules obtained from experienced human operations.

C. Control a steam engine and a boiler combination by synthesizing a set of linguistic control rules obtained from experienced human operations.
Explanation
Mamdani's Fuzzy Inference Method was designed to control a steam engine and a boiler combination by synthesizing a set of linguistic control rules obtained from experienced human operations. This method allows for the control of complex systems by using fuzzy logic to model human reasoning and decision-making processes. By incorporating linguistic control rules, the system can make intelligent decisions based on the input variables and the expert knowledge captured in the rules.

### What Is The First Step Of the Fuzzy Logic Toolbox?

• A.

Fuzzification of the input variables

• B.

Defuzzification

• C.

Application of the fuzzy operator (AND or OR) in the antecedent

• D.

Aggregation of the consequents across the rules

A. Fuzzification of the input variables
Explanation
The first step of the Fuzzy Logic Toolbox is the fuzzification of the input variables. Fuzzification involves converting crisp input values into fuzzy sets, which allows for the representation of uncertainty and imprecision in the input data. This step is essential in fuzzy logic as it enables the system to handle and process vague and ambiguous information.

### What Is The Input And Output Of Step 2 - Apply Fuzzy Operator?

• A.

The input is a single truth value, and the output has two or more values.

• B.

The input is a value greater than one, and the output is a value less than the input.

• C.

The input and output have both the same values.

• D.

The input has two or more values, and the output has a single truth value.

D. The input has two or more values, and the output has a single truth value.
Explanation
The correct answer is that the input has two or more values, and the output has a single truth value. This means that the fuzzy operator takes multiple values as input and produces a single truth value as output. This suggests that the fuzzy operator is performing some kind of aggregation or summarization of the input values to generate a single result.

### What Is The Equation For Probabilistic?

• A.

Probor (a,b) = a-b + ab

• B.

Probor (a,b) = ab + ab

• C.

Probor (a,b) = a+b - ab

• D.

Probor (a,b) = a/b x ab

C. Probor (a,b) = a+b - ab
Explanation
The equation for probabilistic is Probor (a,b) = a+b - ab. This equation calculates the probability of both events A and B occurring by adding their individual probabilities (a+b) and subtracting the probability of both events happening together (ab). This equation follows the principles of probability theory and is commonly used in various statistical and probabilistic calculations.

### What Is The Input And Output Of Step 3 - Apply Implication Method?

• A.

Input is a fuzzy set, but the output is a whole value.

• B.

Input is a whole value, but the output can be a fuzzy set.

• C.

Input and output have the same value.

• D.

Input is a smaller value than the output value.

B. Input is a whole value, but the output can be a fuzzy set.
Explanation
Step 3 - Apply Implication Method takes a whole value as input, but the output can be a fuzzy set. This means that the input is a definite value, while the output can have different degrees of membership to different fuzzy sets. The implication method is used to determine the degree to which the input value is associated with each fuzzy set in the system.

### What Is The Purpose Of Aggregation?

• A.

To gather all the different fuzzy set outputs and combine them into a single fuzzy set outputs.

• B.

To gather all the possible inputs and use the average to gain an output.

• C.

To gather all the different fuzzy set outputs and average them out to get a single value.

• D.

To subtract all the output fuzzy set values from the input values.
