Fuzzy Logic Toolbox Graphical User Interface Tools
In this topic, you use the Fuzzy Logic Toolbox graphical user interface (GUI) tools to build a Fuzzy Inference System (FIS) for the tipping example described in The Basic Tipping Problem.
Use the following GUI tools to build, edit, and view fuzzy inference systems:
Fuzzy Inference System (FIS) Editor to handle the high-level issues for the system—How many input and output variables? What are their names?
Fuzzy Logic Toolbox software does not limit the number of inputs. However, the number of inputs may be limited by the available memory of your machine. If the number of inputs is too large, or the number of membership functions is too big, then it may also be difficult to analyze the FIS using the other GUI tools.
Membership Function Editor to define the shapes of all the membership functions associated with each variable
Rule Editor to edit the list of rules that defines the behavior of the system.
Rule Viewer to view the fuzzy inference diagram. Use this viewer as a diagnostic to see, for example, which rules are active, or how individual membership function shapes influence the results
Surface Viewer to view the dependency of one of the outputs on any one or two of the inputs—that is, it generates and plots an output surface map for the system.
These GUIs are dynamically linked, in that changes you make to the FIS using one of them, affect what you see on any of the other open GUIs. For example, if you change the names of the membership functions in the

    Takagi-Sugeno Fuzzy Interference Systems Analysis

    The FIS for males is shown in figure 2 and it is similar to the FIS for females. The subcategories for each attribute as shown in Figure 1, is taken as members for the corresponding fuzzy variable. The detailed depiction of these membership functions are shown in Figure 5. The members of most input variables remain the same for the FIS of both males and females, with the exception of the input variables ICD-O and occupation. There exist two membership structures for the input occupation due to the inclusion of the attribute housewife for females as shown in 5e and 5f.As for the membership function ICD-O for male and female shown in 5a and 5b, the structure differs as the top five malignancies for each gender is different in…

    Fuzzy Logic Ideas: Forest Road Constructions And Natural Environment

    large scale control process and control systems (Sugeno et al.,1993). Fuzzy logic is the most prominent approach for systems involving nonlinearities and lack of analytical models. The main advantage of this approach is that incorporates in advance qualitative information about the system behavior. Fuzzy logic is indispensable for the analysis of systems whose sharp representation with mathematical models is poor (Pappis et al., 2000). In this study fuzzy logic is used to detect the forest roads on the generated DTM of the study area and the input data we have is the elevation of each location. The forest road borders are not sharp and there is an uncertainty that makes difficult to assign crisp values to DTM cells based on their road membership (elevation differences between road and non-road locations are…

    Fuzzy Logic

    Fuzzy logic is a branch of artificial intelligence that deals with reasoning algorithms used to emulate human thinking and decision making in machines. These algorithms are used in applications where process data cannot be represented in binary form. For example, the statements “the air feels cool” and “he is young” are not discrete statements. They do not provide concrete data about the air temperature or the person’s age (i.e., the air is at 65°F or the boy is 12 years old). Fuzzy logic interprets vague statements like these so that they make logical sense. In the case of the cool air, a PLC with fuzzy logic capabilities would interpret both the level of coolness and its relationship to warmth to ascertain that “cool” means somewhere between hot and cold. In straight binary logic, hot would be one discrete value (e.g., logic 1) and cold would be the other (e.g., logic 0), leaving no value to represent a cool temperature (see Figure 17-1).…

    We address the problem of two-dimensional (2-D) shape representation and matching for large image databases. The boundary contour of the object must include the boundary part which is entirely inside the outline of the object. For this experiment we used canny function for boundary extraction. In this work chain code is main feature as shown in fig.1 which is basic element of boundary, from which boundaries main parts such as curves, angles, vertical lines, horizontal lines, cross lines are formed. For spatial relations we divide whole boundary…
