Then the constellation set C = [{[[PHI].sub.b]}.sup.B-1.sub.b=0] is called a framework of the full diversity USTM constellation based on antipodal points on [G.sub.T,M].
The expression (5) defines a function f : {[[phi].sub.1]; [[phi].sub.2], [[phi].sub.3], [[phi].sub.4]} [right arrow] [[PHI].sub.b] that is, four complex numbers are mapped into a unitary matrix similar to (5) which is a point of the USTM constellation, or f : [{[A.sub.k], [[phi].sub.k]}.sup.4.sub.k=1] [right arrow] [[PHI].sub.b], where [[phi].sub.k] [member of] C and [A.sub.k], [[phi].sub.k] [member of] R.
If the complex elements [[phi].sub.k] [member of] C (k = 1,2,3,4) of each unitary matrix (a constellation point) are referred as to the parameter of the model for the underlying system, such as USTM, then the parameters [A.sub.k], [[phi].sub.k] [member of] R can be thought of the hyperparameter of the same system.
In Section 3.2, the searching orthogonal USTM constellation based on the antipodal points was provided.
[4] presented the following Algebraic orthogonal (AO) scheme of USTM:
An AO USTM constellation is denoted as [C.sub.AO] = {[X.sub.k,l] | (k,l) [member of] F x F}.
Creating best graduates, who can think, innovate and invent, is the driving force of USTM.
The information stored in STM includes the new information from USTM, the information processed in STM, or the information recalled from LTM.
Where [A.sub.id] denotes the identity of an agent; Loc represents the position of an agent in the image, that is, the center of a candidate target; Fit symbolizes its fitness, which is defined by the similarity between the candidate target and the object template; and MS = {USTMS, STMS, LTMS} is a set of hominine memory spaces of an agent for information storage, where USTMS, STMS, and LTMS stand for the ultrashort-term memory space, short-term memory space, and long-term memory space, respectively.
UsTMS, STMS, and LTMS represent the three-stage memories, respectively.
The templates stored in STMS include the estimated template transferred from USTMS, the updated templates in STMS, or the templates recalled from LTMS.
First, the estimated template of the current frame is stored into USTMS and checked against the current template in STMS (the first one).
