(1994) paired an abstract picture, member of an equivalence class
, with mild electric shock (US) that elicited a galvanic skin response (GSR).
Assuming that the first n facets intersect at a vertex, we can choose a representative [LAMBDA] = ([I.sub.n]|[[LAMBDA].sub.*]) for the D-J equivalence class
of [lambda], where [I.sub.n] is the n x n identity matrix and [[LAMBDA].sub.*] is an n x(m - n) matrix.
If [alpha] = < a, [[mu].sub.[alpha]], [v.sub.[alpha]] > [epsilon] IF[[rho].sub.S](R), then we refer to the equivalence class
of [mathematical expression not reproducible], and we refer to the family of all equivalence classes
of a modulo [mathematical expression not reproducible].
If (u, v) [member of] R, it indicates that the objects u and v belong to the same equivalence class
with the equivalence relation R; they are indiscernible.
In a similar way as before, [[alpha]] [conjunction] will denote the equivalence class
with respect to ~[conjunction] that contains [alpha].
However, the product may contain functionally dependent components that have to be found and removed, which just means finding the simplest representative in the equivalence class
for [alpha] x [beta].
The data, which is replaced by the equivalence class
in the anonymization protection algorithm, is more likely to be found in its own laws, is usually used to reflect the development of the object, and is conducive to data mining for partners.
As an application of the main results, it is shown that if we identify every fuzzy number with the corresponding equivalence class
, there would be more differentiable fuzzy functions than what is found in the literature.
Figure 3b is a partition with four equivalence classes
, and each equivalence class
has four points.
So the next level of privacy has been provided using the method called l-diversity  which contains l well represented distinct values within an equivalence class
. Though privacy is improved in the l diversity method, it suffers from similarity attack and skewness attack.
Specifically, the sample can be two stimuli of the same equivalence class
or two stimuli of distinct classes.
