Degree of Membership of a Value in a Fuzzy Set
Fuzzification
Retrieve the matched cases from the case base.Convert the case weight numerical value into the crisp value.This phase generates a fuzzy input set.
Build the Fuzzy Rules (Inference)
Assign zero value to the unused requirements in the retrieved case with respect to given input requirements.Adjust the given input to the value 100 % by reducing the requirement value with equal priority.Generating the fuzzy input requirement value [0,1]
Defuzzification
Fuzzy output set in given as input to this phase. i.e., the best case from retrieved cases.Converting the fuzzy output to the Boolean value for the acceptance of cases.
1. Input: Given the input requirements as {r1, r2,}
2. Retrieve all the matched cases from the case base with respect to the given input.
3. Finding out the value for each matched case with respect to the given input requirements
4. Example: matched Case = {r1, r2, r3…}
5. Assigning zero value to the unnecessary requirement
{r1, r2, 0 ...} (rule1)
6. Identifying the r1, r2 … values in each matched retrieved case
7. Adjust the given input to the value 100 % by reducing the requirement value with equal priority.
8. Adding all case requirement values to generate a case value between 0.0 to 1.0 ranges
9. Member function =
10. Retrieving all the matched case between the given ranges low to high.
Sample Scenario:
Input=…

Haack On Fuzzy Logic Essay
2787 Words  12 PagesHaack On Fuzzy Logic ABSTRACT: Much of the progress in modern logic beyond Aristotle is due to the invention of a precise and powerful formalism, and this is why Haack is reluctant to weaken it. What motivates her to regard deviant and fuzzy logic as extensions rather than rivals of classical logic is its demonstrated capacity for refinement and progress. Thus she sharply distinguishes between a logic dealing with fuzzy concepts (she accepts), and one which is itself fuzzy, i.e., where "true"…

Assessing Present Values: Problem Sets
931 Words  4 PagesAssessing Present Values The concept of the time value of money reflects the way that a set amount of money today will not have the same value in the future. There are a number of tools which may be used to assess the impact on time on the value of money (Wright, 1990). Assessing the impact on time may be undertaken by looking at a cash flow to be received in the future and then discounting it to find the value of the future amount in today's money. This has a great deal of value as it may be used…

Image Fusion Technique Based on PCA and Fuzzy Logic Part 2 Essay
653 Words  3 Pagesbased on fuzzy sets The fuzzy logic approach is widely used in image processing. The fuzzy logic gives decision rules and fusion motivation for image fusion [17]. the two inputs images are converted into membership values based on a set of predefined MFs, where the degree of membership of each input pixel to a fuzzy set is determined. Then, the fusion operators are applied to the fuzzified images. The fusion results are then converted back into pixel values using defuzzification. 1) Fuzzy sets: The…

The Value of a College Degree

Some of these factors include existing social class, field of study, undergraduate vs. advanced degrees, race or gender, selection of institution, and parental resources. The general hypothesis of this study is “Is a College Degree Still the Great Equalizer?” This issue was the source of study by Florencia Torche at New York University. Using different cohort groups and conducting various survey methods, this study was able measure the effects of certain college degrees (i.e…

Value of a Bachelors Degree
1834 Words  8 PagesJune 1, 2013 ENG 1120011S Is a Bachelors Degree Only Worth the Prestige? Having a bachelor degree was a way of showing how successful you have become in your life. The value of these degrees has come into question recently. The value of a bachelor’s degree has dropped significantly over the years. We will look into why the value of the degree has depreciated over the years. For starters, someone with a Bachelors degree could have expected to receive top priority when being considered for a…

Seminar Report on Fuzzy Logic
6250 Words  25 PagesABSTARCT Fuzzy logic has rapidly become one of the most successful of today's technologies for developing sophisticated control systems. The reason for which is very simple. Fuzzy logic addresses such applications perfectly as it resembles human decision making with an ability to generate precise solutions from certain or approximate information. While other approaches require accurate equations to model realworld behaviors, fuzzy design can accommodate the ambiguities of realworld in human language…

Brief Explanation of the Basic Framework of the Principal Componant Analysis and Fuzzy Logic
573 Words  3 PagesPRELIMINARIES This section expands a brief explanation of the basic framework of the principal component analysis and fuzzy logic, along with some of the key basic concepts. A. The principal component analysis (PCA) The Principal component analysis (PCA) is an essential technique in data compression and feature reduction [13] and it is a statistical technique applied to reduce a set of correlated variables to smaller uncorrelated variables to each other. PCA is considered as special transformation…

It is a global community and power and has a huge influence on our world today in many aspects, and has been slowly built up to what it is today through…

Fuzzy Logic Essay
1475 Words  6 PagesFuzzy Logic Fuzzy Logic is a term used to identify a new trend of quantifying partial truths. One disadvantage of most rule sets that they cannot process inconsistent data. Fuzzy logic is a superset of conventional logic that has been extended to handle the concept of partial truth, being values that lie between "completely true" and "completely untrue". Dr. Lotfi Zadeth of UC/Berkley first introduced it in the 1960s as a means of modeling the uncertainty of natural language. All this…
