Kurzbeschreibung

The Algorithms similar to SVD, Eigen decomposition, Gaussian mix version, HMM and so forth. are almost immediately scattered in numerous fields. There is still a necessity to gather all such algorithms for fast reference. additionally there's the necessity to view such algorithms in program viewpoint. This e-book makes an attempt to meet the above requirement. The algorithms are made transparent utilizing MATLAB courses.

Figure 1-13. Fuzzy system 34 Chapter 1 Figure 1-14. Relaionship between crisp value and Fuzzy membership value for the variable X The crisp values ranges from 0 to x2 belong to the set Xsmall. The crisp values ranges from x1 to x3 belong to the set Xmedium. The crisp value ranges from x2 to x4 belongs to the set Xlarge. The crisp value from x1 to x2 of the Xsmall set and Xmedium set with different membership value as mentioned in the Figure 1-14. Corresponding membership value decreases gradually from 1 to 0 in the Xsmall set.

INDEPENDENT COMPONENT ANALYSIS Consider ‘m’ mixed signals y1(t), y2(t)…ym(t) obtained from the linear combination of ‘n’ independent signals x1(t) , x2(t) … xn(t) , where n>=m is given below. 1 ICA for Two Mixed Signals The samples of the signals x1(t) and x2 (t) are represented in the vector form as x1=[x11 x12 x13 …x1n] and x2=[x21 x 22 x23 … x2n] respectively. The signals y1(t)=a11*x1(t)+a12*x2(t) and y2(t)=a21*x1(t)+a22*x2(t) are represented in the vector form as y1=[y11 y12 y13 …y1n] and y2=[y21 y22 y23 … y2n] 53 2.

This is due to the fact that the initial simulated temperature of the annealing process is high. 1. Artificial Intelligence 21 Figure1-7 Illustration of Simulated Annealing 1 As iteration increases the simulated temperature is decreased and the value selected for the variable ‘x is moving towards the global minima point as shown in the figure 1-7. Thus values assigned to the variable ‘x’ for the first few iterations (about 10 iterations in this example) is not really in decreasing order of f(x).
