Lotfi Zadeh's Fuzzy Logic

1219 Words5 Pages

Fuzzy logic (FL) is firstly developed in 1956 by Lotfi Zadeh in the Unites State of America as a mathematical tool for dealing with uncertainty. It offers techniques to deal with imprecision and information granularity (Sivanandam et al. 2007). Fuzzy logic is a system of concepts, principles, and methods for dealing with models of reasoning that are approximate rather than exact (Demmico and Klir 2006). In spatial earth sciences applications, FL has two main advantages: (i) it is straightforward to apply within GIS platform and (ii) it does not require the statistical distribution of the data to be known (Pradhan 2011). Contrary to the crisp set, the boundary of a fuzzy set is not precise. Crisp sets only allow full membership, whereas fuzzy sets allow partial …show more content…

One of the difficult challenges of the application of fuzzy logic in spatial earth science disciplines is how to assign fuzzy membership values of conditioning factors (Bui et al. 2014). In this context, different methods have been applied to address this issue. For examples, techniques such as Cosine Amplitude (Kanungo et al. 2009l; Rather & Andrabi, 2012), frequency

    The knowledge base consists of a collection of fuzzy if-then rules of the following form: $R^{l}$: if $x_1$ is $F_1^{l}$ and $x_2$ is $F_2^{l}$ and $ldots$ and $x_n$ is $F_n^{l}$, then is $G^{l},~l=1,2, cdots ,n$, where $x=[x_1,cdots,x_i]^{T}$ and $y$ are the FLS input and output, respectively. Fuzzy sets $F_i^{l}$ and $G^{l}$, associated with the fuzzy functions $mu_{{F_i}^{l}}(x_i)$ and $mu_{{G}^{l}}(y)$, respectively. $N$ is the rules inference number. \Through singleton function, center average defuzzification and product inference cite{shaocheng2000fuzzy}, the FLS can be expressed as: For any continuous function $f(x)$ defined on a compact set $Omegain R^n$, there exists a fuzzy system $y(x) = heta ^T

    For this case study, I selected these indicators because they met indicator evaluation criteria for UNCCD (15) and the SMART concept – Specific, Measurable, Achievable, Relevant and Time-related. The indicators estimation will depends on the Remote Sensing (RS) data. As explained in (16a), the RS (Landsat) data is suitable for quantification of spatio-temporal desertification or (ESAs) because it allows researcher to go back and examine the change. Here, I should mention that desertification is a slow process which takes years to happen (17a). For the RS data, I will request the Landsat data for Biskra for three years.

Geographic data allows identifiable information to be offered to subscribers with the encouragement of geographical indicators. Display tools offer a realism of visual effects and the most applicable advantages. Photogrammetry and Remote Sensing, spatial statics and Geographic Information Systems (GIS): Systems of these nature offer geographers collaborative and analyzed information far more unique than traditional research techniques (Geographic Information Systems as an Integrating Technology: Context, Concepts, and Definitions,2015).

    Social platforms are the masks of today’s society, therefore, individuals are becoming more complacent to their feelings and relationships they have with others. Having social media at our fingertips via cell phones allows a mask of false happiness. Adolescents use the social platforms like Facebook, Instagram and Twitter to hide what they really feel. In the book, Fahrenheit 451 written by Ray Bradbury gave us insight on a society that shies away from uniqueness and deep thought. Today the American culture is too afraid to step out of their comfort zone and really accept what life has to offer.
