box–muller transformpseudo‐random number generatorsIn a recent paper, Neave has observed that the agreement between the observed and the expected frequencies is poor in the two tails of a normal distribution when the random normal deviates are generated by a multiplica tive congruential scheme: xr...
Since the normal distribution occurs frequently in economic and financial modeling, one often needs a method to transform low-discrepancy sequences from the uniform distribution to the normal distribution. Two well known methods used with pseudorandom numbers are the Box–Muller and the inverse ...
对于d=2,通过变量代换,利用球极投影变换可以导出Box-Muller公式。 5) box-muller transform Box-Muller变换 6) Box algorithm Box算法 1. TheBox algorithmis an important direct searching method for optimal engineering design, which is applicable toresolve optimization when the object function can t be gi...
However, other transformations are possible, amongst which the transformation by Box and Muller. The danger in using a non-separable transformation is that it might break the low discrepancy structure which makes quasi-Monte Carlo converge faster than regular Monte Carlo. We examine several ...
Box-Muller公式1. Through variable substitution, Box-Muller formula can be derived by means of stereographic projection transformation for d=2. 对于d=2,通过变量代换,利用球极投影变换可以导出Box-Muller公式。2) box-muller transform Box-Muller变换...
There are many methods available to transform computed pseudorandom uniform deviates into normal deviates, for example the “ziggurat method” of Marsaglia and Tsang 2 . One of the most popular methods is that of Box and Müller 3 . Though not optimal in its properties, it is easy to underst...

(See for example http://en.wikipedia.org/wiki/Box%E2%80%93Muller_transform.) If you increase the value of sigma_noise, then you'll get more variance. Also, your code can be vectorized to have a significant speedup. Replace your for loop with: 테마복사 AWGN_noise = sigma_noise...
Cryptographic algorithms implemented in embedded devices must withstand Side Channel Attacks such as the Differential Power Analysis (DPA). A common method of protecting symmetric cryptographic implementations against DPA is to use masking techniques. Ho
Brain activity pattern recognition from EEG or MEG signal analysis is one of the most important method in cognitive neuroscience. The supFunSim library is a new Matlab toolbox which generates accurate EEG forward model and implements a collection of spatial filters for EEG source reconstruction, inc...
