Linguistic modifiers

Figure 8.18 provides examples for linguistic modifiers, such as very, more or less, and middle. The membership function high is normalized to the interval [0,1] and reads as (Figure 8.20)... 

The learning element consists of a Performance Index (PI) table combined with a rule generation and modification algorithm, which creates new rules, or modifies existing ones. The structure of a SOFLC is shown in Figure 10.17. With SOFLC it is usual to express the PI table and rulebase in numerical, rather than linguistic format. So, for... 

Fuzzy modifiers (linguistic hedges) very, quite, extremely,... 

All of these linguistic terms except fuzzy modifiers are represented in each context by appropriate fuzzy sets. Fuzzy predicates are represented by fuzzy sets defined on universal sets of elements to which the predicates apply. Fuzzy truth values and fuzzy probabilities are represented by fuzzy sets defined on the unit interval [0,1]. Fuzzy quantifiers are either absolute or relative they are represented by appropriate fuzzy numbers defined either on the set of natural numbers or on the interval [0,1]. Fuzzy modifiers are operations by which fuzzy sets representing the various other linguistic terms are appropriately modified to capture the meaning of the modified linguistic terms. 

The most essential stage in human brain development occurs during the prenatal period and the first four year of life. Just after birth, the intrinsic nature of the individual, including epigenetic and genetic information, combines with extrinsic environmental factors and act in concert to modify brain domains to cope with cognitive, social, linguistic and other... 

Linguistic Variables Verbal fuzzy expressions are described by fuzzy theory by means of linguistic variables for example, the solubility of a substance in water can be characterized by the fuzzy terms high and low. If the linguistic variables are further to be distinguished, the so-called modifiers are applied.

Linguistic hedges are special linguistic terms by which other linguistic terms are modified. A linguistic hedge or modifier is an operation... 

Since we wanted a more tightly coupled system, and had elected not to modify Infer, we embarked on a re-implementation of DDD within Infer (Fig. 3(b)). There were three major roadblocks in the way of this approach, roughly, semiotic, linguistic, and metalinguistic in character. 

These are linguistic terms that modify other linguistic terms, for example, very, more or less, fairly, extremely. They may be used to modify fuzzy predicates, fuzzy truth-values, and fuzzy probabilities. The fuzzy set that defines the hedge is called a modifier.
