Fuzzy logic has been used in numerous applications such as facial pattern recognition, air conditioners, washing machines, vacuum cleaners, antiskid braking systems, transmission systems, control of subway systems and unmanned helicopters, knowledge-based systems for multiobjective optimization of power systems, ...

Logic Gates, Boolean Algebra and Truth Tables Boolean Algebra specifies the relationship between Boolean variables which is used to design combinational logic circuits using Logic Gates. The truth table shows a logic circuit's output response to all of the input combinations.

The fuzzy logic checks for the extent of dirt and grease, the amount of soap and water to add, direction of spin, and so on. The machine rebalances washing load to ensure correct spinning. Else, it reduces spinning speed if an imbalance is detected.

Artificial intelligence allows business owners to provide a more personalized experience to their customers. AI can analyse vast data way more efficiently. It can quickly identify patterns in the information- such as past buying history, buying preferences, credit scores and other common threads.

Algorithms are always unambiguous and are used as specifications for performing calculations, data processing, automated reasoning, and other tasks. As an effective method, an algorithm can be expressed within a finite amount of space and time, and in a well-defined formal language for calculating a function.

The main difference between classical set theory and fuzzy set theory is that the latter admits to partial set membership. A classical or crisp set, then, is a fuzzy set that restricts its membership values to {0, 1}, the endpoints of the unit interval.

Inductive Reasoning. During the scientific process, deductive reasoning is used to reach a logical true conclusion. Another type of reasoning, inductive, is also used. ... It is important to learn the meaning of each type of reasoning so that proper logic can be identified.

Logical operators. The logical operators in Python are used to combine the true or false values of variables (or expressions) so you can figure out their resultant truth value. Three logical operators are available in Python: 1. and – returns True only if both operands are true.

Boolean Logic is a form of algebra which is centered around three simple words known as Boolean Operators: “Or,” “And,” and “Not”. At the heart of Boolean Logic is the idea that all values are either true or false.

Description. This function computes fuzzy membership values using a spline-based pi-shaped membership function. You can also compute this membership function using a fismf object. For more information, see fismf Object. This membership function is related to the smf and zmf membership functions.

The Mamdani fuzzy inference system was proposed as the first attempt to control a steam engine and boiler combination by a set of linguistic control rules obtained from experienced human operators. ... Since the plant takes only crisp values as inputs, we have to use a defuzzifier to convert a fuzzy set to a crisp value.

Even if all of the premises are true in a statement, inductive reasoning allows for the conclusion to be false. Here's an example: "Harold is a grandfather. Harold is bald. ... Deductive reasoning allows them to apply the theories to specific situations.

In mathematics, the membership function of a fuzzy set is a generalization of the indicator function for classical sets. In fuzzy logic, it represents the degree of truth as an extension of valuation. ... Membership functions were introduced by Zadeh in the first paper on fuzzy sets (1965).

Several studies conclude that up to 90 percent of the decisions we make are based on emotion. We use logic to justify our actions to ourselves and to others. Take note that emotion will always win over logic and that imagination will always win over reality.

frbs: Fuzzy Rule-Based Systems for Classification and Regression Tasks. An implementation of various learning algorithms based on fuzzy rule-based systems (FRBSs) for dealing with classification and regression tasks. Moreover, it allows to construct an FRBS model defined by human experts.

The goal of the inferential statistics is to draw conclusions from a sample and generalize them to the population. It determines the probability of the characteristics of the sample using probability theory. The most common methodologies used are hypothesis tests, Analysis of variance etc.

The rule base of a fuzzy system is interpreted as a neural network. Fuzzy sets can be regarded as weights whereas the input and output variables and the rules are modeled as neurons. Neurons can be included or deleted in the learning step. Finally, the neurons of the network represent the fuzzy knowledge base.
