平均因子分解法应用于正定矩阵
平均因子分解法，适用于正定矩阵First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X=U U, where U is the square root matrix of X, and satisfies:
(1) U U = X
(2) U is upper triangular (that is, it has all zeros below the diagonal).
It seems that the assumption of positive definiteness is necessary. Actually, it is "positive definite" which guarantees the existence of such kind of decomposition. -Average factor decomposition method applied to positive definite matrix First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X = UU, where U is the square root matrix of X, and satisfies: (1) UU = X (2) U is upper triangular (that is, it has all zeros below the diagonal).

仿生模式识别 目标跟踪
用仿生模式识别来训练目标，在视频序列中跟踪目标
function [sausage, num] = hypersausage_construct(P)
%按照样本给定的顺序去求解超香肠神经元
[~, W] = size(P);%W是训练样例的个数
sausage = [];
for i = 2:W
temp = power_two(P(:, i - 1), P(:, i));%构建第i-1个神经元 //temp是一个行向量
%temp = power_three(P(:, i - 2), P(:, i-1),P(:,i));
sausage = [sausage temp];
end
sausage = [sausage P(:, end)];
num = (size(sausage, 2) - 1) / (W - 1);
